Analytical Testing

Gas Chromatography Mass Spectrometry (GC/MS)

Argen has developed advanced GC/MS techniques that are unmatched in the rubber/polymer and oil & gas industries.  We have Ph.D. analytical chemists with decades of experience in rubber compounding and polymer analysis.  This powerful combination allows us to get our customers answers to a multitude of questions.

  • What is this unknown or foreign material?
  • What is being extracted or leached from of a material?
  • What is being outgassed in a material?
  • Are antioxidants present in a material?
  • What has been absorbed in a material?
  • What are the impurities in a material?

Pyrolysis GC/MS

  • Sample Requirements:  < 1 milligram of solid or liquid
  • Programmable Temperature Range: ambient to 1,200°C
  • Heating Rate: 0.01°C/ms to 20.0°C/ms

Thermal Desorption GC/MS

  • Sample Requirements:  2-30 milligram of solid or liquid
  • Programmable Temperature Range: ambient to 395°C
  • Liquid Nitrogen Cryo-Trap
  • Adsorbent Cartridge Capability

Headspace GC/MS

  • Sample Requirements:  variable size, solid or liquid
  • Injection: gas-tight syringe
  • Mass Spectral Deconvolution of Volatiles

GC/MS of Liquids

  • Sample Requirements:  typically 1 microliter sample
  • Mass Spectral Deconvolution and Identification of Components
