We ARE The Particle Testing Authority

Since the Particle Testing Authority started as a division of a leading manufacturer of particle characterization equipment – Micromeritics Instrument Corp. – we have been uniquely positioned to offer our customers expertise that is unrivalled by other contract analytical services laboratories.  Due to our continual engineering, design, development and manufacturing expertise for more than 55 years, we literally know the instrumentation from cradle to grave.

This experience enables us to get the very most out of the instrumentation and determine which test methods and techniques will produce the best results possible.  In addition, our application scientists have >200 years of combined experience in solving real-life process and quality problems with pharmaceutical and biological products.  This means that we have the ideal combination of high-quality instrumentation and application expertise to support your contract testing needs.  Whether you are outsourcing your pharmaceutical testing and analysis for a short-term project, extending your resources, creating a stop gap until you build the capabilities in-house, or experience needs that grow along with your business; the Particle Testing Authority is the ideal partner for you.

Specifically, we offer the following routine services:

  • Particle Size Analysis – Particle size distribution using a variety of techniques including laser light scattering, sedimentation, electrozone sensing, dynamic image analysis, sieves and microscopy
  • Surface Area Analysis by gas adsorption - B.E.T. and Langmuir surface area methods using N2 or Kr as adsorptive gas
  • Pore Volume or Pore Size Distribution - Macropore, Mesopore and Micropore Distributions by Gas Adsorption and Mercury Intrusion/Extrusion techniques
  • Density Measurements - True density determined using a gas pycnometer, bulk density, envelope density, T.A.P. density, and foam density
  • Chemisorption Experiments - Catalyst characterization methods include percent metal dispersion, metal surface area and TPR/TPD/TPO with mass spectrometry, heat of adsorption & desorption
  • Microscopy Services - Wide range of Microscopy techniques including SEM, TEM, PLM, FTIR, and SWLIM for surface roughness.
  • Thermal Analysis – DSC and TGA
  • Vapor Sorption Experiments – dynamic vapor sorption, inverse gas chromatography, and surface energy
  • Other Analyses - Too numerous to list here; see our website for a complete list of the services offered.
