location: >Particles> Expert system for sizing equipment Particle Size Analysis Equipment Selection and Elimination Procedure Define the particles 1. Do you believe the median average size to be: greater than 1 mm greater than 0.5 mm 0.5 mm to 30 microns 30 to 1 micron less than 1 micron       2. What is the bottom size of interest of the distribution: 100 microns 30 microns 1 micron 0.1 micron 0.01 micron       3. Do you want to count the particles, or just the size distribution: count size distribution both       4. Is your sample in water, solvent or dry: water dry solvent       5. What do you expect the size distribution to be: narrow - single mode wide - single mode multiple modes no idea Define the process 1. What type of measurement is required:   laboratory bench on-line in-situ bench and on-line separate particles for chemical/other analysis       2. Do you want a picture of the particles:   Yes No       3. How long should the analysis take:   Less than 5 minutes less than 15 minutes less than 60 minutes other (longer is OK)       4. What about the suspension concentration? Is it:   high (no dilution possible) high but dilution possible low       5. Do you need two techniques in one device:   Yes No       6. Do you have a mixture of solids:   yes, sized above 20 microns yes, sized below 20 microns no       7. What about the instrument cost? Should it be:   Less than $20000 Less than $40000 Less than $60000 Not important SELECT       OR YOU CAN       THE ABOVE VALUES
