PrintThe instrument provides a particle size distribution without the physical separation required by sieves. Particle size distributions are characterized by percentages of a sample in up to 140 channels covering a total range of 0.12 to 1500 micrometers diameter. This range enables the analysis of smaller particles than can be sized with sieve analysis. An added advantage is that emulsions, suspensions, and pastes can also be tested, as long as a compatible carrier fluid is available. Care must be exercised with non-spherical particles, as the size will be expressed as an equivalent spherical diameter.
Particles are typically dispersed in a compatible liquid carrier fluid (a liquid that does not dissolve or agglomerate particles). Atypical samples may require special handling or technique.

Composition of the sample. Samples need to be either diluted with the continuous phase liquid for emulsions or powders must be dispersed into a solvent that does not dissolve or react with the sample.
Microtrac instrument measures particle size by Laser Diffraction. The test is designed for spherical shaped particles.
While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
