Perkin Elmer Clarus SQ 8T Gas Chromatograph/Mass Spectrometer (GC/MS)

This world class GC/MS to allow for ultra-trace detection limits consistently and reliably – time after time.

What does this mean for our customers?

  • High productivity
  • The new hardware, software and libraries will allow for higher end analysis
  • This instrument allows us greater throughput ability as we can now run Phthalates and Brominated Flame retardants simultaneously if needed
  • The new instrument design allows for less down time for maintenance, and the large pump gets us back up and running faster after maintenance

Perkin Elmer QSight Triple Quad Liquid Chromatography Tandem Mass Spectrometer (LC-MS/MS) System

This top-rated LC-MS/MS system incorporates Ultra High-Pressure Liquid Chromatography (UHPLC) with a dual source, triple quadrupole mass spectrometer. The technology allows for precise measurements of very low concentrations of organic species in a wide range of sample types. NSL has established methods deploying this technique to measure parts per trillion (ppt) levels of polyfluoroalkyl substances (PFAS) in manufactured materials. Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA).

Perkin Elmer FT-IR Spectrometer 3

Another recent addition to our polymer testing laboratory is the world-class Perkin Elmer FT-IR Spectrometer 3. This high-tech system allows our team to perform Fourier-transform infrared spectroscopy (FTIR) services for samples ranging from 4,000-450 cm. Sample applications include, but are not limited to:

  • Pharmaceuticals and Nutraceuticals
  • Chemicals and materials
  • Polymers
