Sieving would pass the particles through a 20mm aperture and classify them as 20mm. (When measuring their own samples, the user would specify a new material by pressing the Materials button). The example below shows the result of transforming a skewed volume distribution to number. Proceed as described above for adding a user. 2. 8. Introduction 3 2. There are many other methods available to do this. Picture bitmaps, GIFs, JPEGs, metafiles and icons. Display background (exited by key press) a display appears, showing the background signal. These assumptions are incorrect for many materials and for small particles they can give rise to errors approaching 30%, especially when the relative refractive index of the material and medium is close to unity, or when the particles are transparent. The Essentials Manual gives information on the following: Site requirements. For example, suppose that days after a measurement the Refractive Index specified as an optical property is found to be incorrect. This phi notation is based on a power of two series where the class boundaries are labelled by the index. 6. Dispersant degassing Selecting the Enable check box causes a degassing routine to be performed each time the tank is cleaned. Use of volume-based results. A record can be deleted but it can never be altered. Menu commands are always shown in bold text. Specify the SOP file to save the changes to as a new SOP. It is possible to zoom into a graph report. Select the Material tab. 1. WebMastersizer2000. When adding very fine material and relying on the action of the ultrasonics to achieve a good dispersion, add less sample than you would expect. Select OK to add the search criterion to the list box in the previous dialogue. Page 6-14 MAN 0384, 87 Understanding the views Chapter 6 When the particle size approaches the wavelength of light the scattering efficiency becomes a complex function with maxima and minima present. 4. They cannot say that the matchbox is 25mm as this is only one aspect of its size. The optimum measurement time depends on the size of the sample, its particle size distribution and the dispersion unit used. To change between reports simply select another report tab. Note the following points regarding the measured data and the analysis: Analysing the measurement data does not permanently alter the data. This dialogue also allows messages to be displayed for the operator before and/or after a measurement. Result Statistics report This report displays various statistics comparing two or more measurements. Once a file has been selected, a Measurement window will appear. i Note The versions of the following dialogues actually seen may differ slightly, depending on the dispersion unit selected. The system measures how much sample is added by monitoring the obscuration of the beam caused by the sample being added to the dispersant. The Span is the measurement of the width of the distribution. Sample fit report This report shows how well the analysis data was fitted to the measurement data. The measurement is now complete. This user manual is a companion to the Mastersizer 2000 Essentials Manual which gives Health and Safety, maintenance and other vital information which all users must read. A tabbed dialogue appears, each tab corresponding to a SOP Wizard dialogue.

Integrated systems for particle sizing. Changes to the graph and table format will be reflected in any printouts of the selected report. Details on interpreting reports can be found in Chapter 6. If a blue refractive index is not given, the Mastersizer assumes that it has the same value as the red refractive index. Items shown in grey are those which are not currently available. The operator can perform all user maintenance routines in the Essentials Manual except for changing the fuses. The supervisor is responsible for the training of the operators. One or more sample dispersion units The sole purpose of a sample dispersion unit is to prepare the sample then deliver it to the optical bench so that it can be measured. The size classes generated can be edited or saved by selecting the Edit Sizes tab. Mastersizer 2000 Page 2-5, 26 Chapter 2 Overview Saving the results After making a measurement the user can save the result in a measurement file by selecting File-Save or Save as (an SOP can be configured to automatically save the results to a measurement file). Select Water from the Dispersant name box. Select the Enable transformation check box and select the relevant Transform Volume to radio button. Obtain the ideal obscuration by finding the range where the result reproducibility is good and the results are independent of the obscuration chosen. Custom calculation. This assumes that: The particle is much larger than the wavelength of light employed. The first choice to consider when measuring a wet sample is the choice of suspension medium (dispersant). Sieve presents the data from the current measurement record as it would be displayed if a stack of sieves had been used for the measurement. The peak of the frequency curve gives the modal diameter, the most commonly occurring particle diameter. 2. This is particularly important for users who are also transforming the result, where small modes in the volume distribution, caused by errors, are magnified and can become dominant when transformed to a number distribution. Page 3-4 MAN 0384, 31 Identifying the features Chapter 3 Three types of cell are available: A wet cell used on the Hydro 2000G/S/SM/MU, detailed later in this chapter. A table or graph can be dragged and dropped into another application by selecting the item, then dragging while holding the Ctrl key.

Select Dairy cream using Hydro 2000G.SOP (or Dairy cream using Hydro 2000S.SOP if using the Hydro 2000S) from the directory C:\Program files\malvern Instruments\Mastersizer 2000\SOP. Many dialogues also have Advice buttons, giving more general advice. The sample concentration is controlled by monitoring the obscuration of the laser beam caused by the sample. Depending on the SOP design, a dialogue may appear asking the user to document the measurement (add comments and observations). When the SOP is run, it automatically runs through the defined measurement procedure, prompting the operator to perform tasks (such as adding the sample). USER INSTRUCTIONS FOR 10 LITRE PORTABLE DEHUMIDIFIER MODEL NO. These connectors attach the cell to the dispersion unit. i Note Only Administrators group members can add or edit user properties. If a sample is taken from the top of the container, mainly large particles will be measured. In most cases the difference is small but the geometric mean is chosen in these calculations as more appropriate to the logarithmic spacing of the fundamental size classes. There are several ways to select an item from the menu bar: Using the mouse to select an item from the menu bar, click the left mouse button once on the menu. voltage 250V ~ 3. The dialogue is split into two sides. Multiple measurement windows can be displayed at a time. We cannot be held liable. MEDIA KIT| Automatic preparation and dispersion of samples gives true intervention-free operation to free key personnel for other tasks. Typically over 2000 snaps are made for each measurement, with each snap taking 1ms. 3 Mastersizer 2000 www.malvern.co.uk Wet Dispersion Units Many samples are produced as slurries or need to be measured wet in order to achieve good particle dispersion and reproducible results. Page 1-6 MAN 0384, 21 2 Overview Introduction This chapter gives a complete overview of the system. SOP summary To summarise, an SOP measurement generally follows the steps indicated below. Archimedes Archimedes Archimedes Sizing from Buoyant Mass ASD range See all ASD range ASD FieldSpec range ASD FieldSpec range The Gold Standard in Field Spectroradiometers ASD TerraSpec range Options this button gives access to the measurement options. The sample should be correctly mixed before a measurement is taken. Surfactants Adding a surfactant may help in preparation of the sample by removing the surface charge effects on the sample that cause it to float on the surface or clump together. Switch on the dispersion unit(s). Consult the online help for details on how to use result emulation. Add Sample this tab shows how much sample has been added to the tank for measurement. Select one or more records from a measurement file. Any parameter contained in the file can be a search clue. Users who are required to conform to Good Laboratory Practice should keep the results of this test on file. As stated above, the choices for the options of both manual and SOP measurements are basically the same; most information in this section applies equally to manual measurements. Select the Material tab. Select the Measurement tab (shown below). If unsure, analyse the sample and observe the obscuration figure. Now certified and compliant with EN50131, EN50136 Security Grade 4 ATS6, Wireless Keyboard & Optical Mouse. The sample dispersion units are referred to in full ( the Hydro 2000G or the Hydro 2000MU ), or as the dispersion unit. Another use for frequency curves is to compare results from different measurements. Increase the pump/stirrer speed. Remember that the Mastersizer measurement is fundamentally a measurement of the volume distribution - transforming the result into a surface, length or number distribution is a mathematical process that may amplify any error in the original result, especially at the fine end of the size distribution. Select Finished measuring. If this is compared to a measurement with the sample taken from the centre of the container the results will differ noticeably. Rapidly increasing obscuration. This main interface allows the user to define an SOP, run a measurement, display the results and print reports. i Note If a material is created or modified, the computer calculates a new scattering model. Select Measure-Manual. The sample may dissolve; this can usually be seen visually. Dry powders, for example, tend to separate out if stored for some time or vibrated. This manual contains, Visual Tutorial Basic Edition 1 Visual Basic Edition Tutorial www.visuallightingsoftware.com Visual Tutorial Basic Edition 2 Basic Edition Tutorial Introduction In this tutorial, you will use the Visual, PART NO. The detector array takes a snapshot of the scattering pattern. Measuring new samples what to do for a new material.

This allows the measurement to be repeated at a later date. This display disappears when the time-out set in the Time-out box is exceeded. For systems plumbed into the mains supplies a small header tank may overcome this problem. Sample splitters/rifflers are also available for liquid samples. The SOP automatically measures an electrical background, aligns the optical system and measures the optical background. Page 4-22 MAN 0384, 59 Making measurements - a tutorial Chapter 4 Measurement dialogue Use the Measurement dialogue to set the measurement and background times. Safety precautions. If the administrator used the User cannot change password option, this prevents a user from changing their password. Measure Sample this tab displays the scattering information during the actual measurement. Suppose, for simplicity, that a sample consists of only two sizes of particle, 50% by number having a diameter of 1 micron and 50% by number a diameter of 10 microns. For example, if the user has just completed a background measurement (and the Pause between stages check box is enabled), pressing Next takes them to the Add Sample tab. 2. This at a glance inspection of the results is difficult if the result is shown as a cumulative plot. The instrument and the samples to be measured may be hazardous if misused. Measurement options describes the series of dialogues which comprise the SOP Wizard. Installation (in case the system has to be moved after its initial installation by Malvern Instruments personnel). SOPs SOPs are user-defined procedures that are easily programmed into the software to allow the same type of sample to be measured in a consistent way. Serial number of the optical bench and dispersion unit(s). The system automatically detects which dispersion unit and cell are fitted and changes this dialogue to suit. Click Options-Security settings and in the Security Settings dialogue shown below select the Enable security check box and click OK. Mastersizer 2000 Page 10-3, 128 Chapter 10 Security Security is now enabled on the system. If obscuration increases rapidly, particles may be attaching themselves to the cell windows due to surface charges.
