As an analytical contract service lab, Particle Technology Labs specializes in particle size and material testing services for clients from many different industries.  Particle Size Distribution testing is just one of the many services offered.

A Particle Size Distribution Analysis (PSD) is a measurement designed to determine and report information about the size and range of a set of particles representative of a material.  Particle size and distribution analysis of a sample can be performed using a variety of techniques, each with advantages and disadvantages, depending on the sample properties and question at hand.

Knowing and controlling the particle size distribution of the primary particles and/or agglomerates present in a material is of utmost importance for:

research

product development

processing

handling

packaging

quality control

The number of standard organizations and regulatory agencies who have current particle size distribution guidance documents and/or specification requirements is a clear indication of the importance of this information.

Particle Size Distribution is usually expressed from the technique by which it is determined. Particle Technology Labs (PTL) uses a variety of different techniques in order to produce the most accurate particle size analysis possible, based on sample characteristics and the analytical question asked.  Many factors influence the choice of technique such as, but not limited to:

detection limits

particle size range

sample presentation

sample concentration

solubility

particle shape

Our many years of experience and vast array of analytical techniques employed allow PTL to consult with the client to determine the best technique for his or her exact needs. This experience also includes proper techniques for sampling as well as sample preparation in order to achieve accurate and precise results.

At PTL, we can also assist with routine particle size distribution testing for release using established methods provided by the client. In these cases, companies find that it is often advantageous to use an independent, regulated laboratory, such as PTL, that provides additional insight, feedback and confirmation not always available with in-house testing.

Particle Size Distribution determination has been used extensively to monitor, control, and investigate material properties in countless industries.
