  • Independent particle characterization services for dietary supplements

    Concurrent with the U.S. Food and Drug Administration’s final rule establishing regulations to require current good manufacturing practices (cGMPs) for dietary supplements, PTL can offer cGMP services to all supplement manufacturers. PTL has sustained its FDA registration since 1994, which involves rigorous inspections by FDA every 2 years or sooner. According to the final rule, proper controls must be in place for dietary supplements to be produced in a consistent manner for identity, purity, strength, and composition. PTL’s particle characterization tests can be conducted following FDA regulations. Valuable testing such as particle size and shape, image analysis, B.E.T. surface area, pore volume and pore size can be analyzed under cGMP compliance. These analyses can give insight into absorption, strength, and composition of the material being processed.

  • Surface Science

    SIMS - for depth profiling, surface composition measurement, and elemental imaging, Hiden's SIMS Workstation provides a complete analytical facility. RGA - The Hiden quadrupole mass spectrometers provide high sensitivity detection capability for the most demanding XHV/UHV vacuum environments. The pulse ion counting detector enables measurement of both positive and negative ions through 7 continuous decades, the integral accumulation mode being used for the capture of discreet particle events. UHV Temperature Programmed desorption studies (TPD) - Hiden Analytical’s 3F/PIC mass spectrometers with pulse ion counting detection are available configured specifically for UHVTPD providing fast, wide dynamic range detection of multiple species, capturing the entire desorption event. The Hiden IDP ion desorption probe is a quadrupole mass spectrometer configured for analysis of low energy ions in electron and photon stimulated desorption studies.
