Top 11 Questions You Should Ask When Buying a Particle Size Analyzer
1. What is the size range you need to measure? Unfortunately, no one technique can measure all possible particle sizes, so the range needed will narrow the potential systems which can be used.
2. What exactly do you want to measure and why? Particle analyzers use many different techniques to arrive at measurements. In order to figure out what technique will work best for your application, you need to define what you are trying to measure and why.
3. Are you trying to characterize different particle types in a single sample?
4. In what “state” should the measurements be made? In many cases, measurement of the particles in the “native state” may not be possible.
5. Is measuring the count or concentration (two different measurements!) of the particles along with size/shape important? If knowing an absolute particle count, or a particle concentration is important, then some techniques will be eliminated immediately.
6. How easy is it to generate reliable data? Think about your users and ask what, if any, specific expertise is required for system set-up and routine use. Then, ask to make a measurement to assess this during the selection process.
7. Can the instrument comfortably handle all your samples? Check the particle size range and the availability of efficient dispersion units for suspension, emulsion, and dry powder analysis.
8. Are there any features that will boost productivity? Ask about measurement times; check how easy it is to switch between sample types and assess maintenance requirements.
9. How does the safety, health, and environment (SHE) performance of the system compare with others? A good dry dispersion unit will minimize the need for wet measurement, for example, cutting dispersant use. If you need containment, then assess its quality.
10. How easy is it to tailor analysis to your precise needs? Check out the software interface, and the process required to develop methods and present your data how you want it.
11. And finally what type of support is available, now and into the future, if things go wrong, or with a new application? Ask about provisions for online education and training.
