Top 11 Questions You Should Ask When Buying a Particle Size Analyzer

 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.

Product of Interest


The T:Genius is an integrated system for DNA and protein analysis, featuring an integrated tablet PC running the highly acclaimed GeneSys automated control system for image capture and editing.

A new generation CCD camera enables you to select an image output of 12.9m pixels. T:Genius uses an f1.0 motor driven zoom lens to enable perfect imaging of any gel or blot. The maximum viewing area is 24 x 20cm which is very large for such a small foot print unit.

Help your Colleagues

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Beckman Coulter PA 800 plus
For the last three years we have been working with a Beckman Coulter PA 800 plus capillary electrophoresis equipment. A month ago we detected an electric issue that we have not been able to solve yet... Advise this member.

DMSO calibration curve is pointing the other way round
This question is regarding Biacore 3000. I have a major problem with the DMSO calibration curve. The curve is pointing the other way round if compared to the standard curve. I am currently using NTA chip to capture-couple the ligand (protein of 30kDa). I am not sure the cause to this problem.

GelDoc-It TS Imager
Need a replacement touch screen for this unit. UVP will not help with a replacement. Anyone ever replace the touch screen on this system? Advise this member.

Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

Bettersize Instruments Ltd. 2000
When I use the particle size analyzer, and when try to understand how the (particle sizevsdiff%) (the red curve) I found that the limit of (diff%) is from (0-5) while there are diff% over 5 which cannot be fitted on the curve, how is this curve work please?  Advise this member.

The accuracy of the pore size determination
Can 2050 accurately determine pore size of 3-10 A? What is it's limit? Advise this member.

Zeta Potential measurements off
We've been testing the BI-ZR3 reference material to make sure we're doing the sample preparation and everything right. We're getting the right conductance (~320uS), the particle size (~300nm) approximate count rate (540 kcps). But our zeta potential has been higher than what it should be (-37mV instead of -52mV). The frequency is also lower (223 Hz) than what the manual says it should be (250Hz). What could we be doing wrong to get the higher zeta potential readings and lower frequencies? Advise this member.
