Check-standards

Check-standards contain a range of routine and challenging analytes, and are useful when setting up instrumentation or troubleshooting. Markes supplies two types of check-standard, both prepared on conditioned Tenax TA sorbent tubes.
  • Instrumentation check-standards contain benzene, toluene, o-xylene, isobornyl methacrylate (IBMA) and dioctyl phthalate at a nominal concentration of 90 ng/μL for each component. A single check-standard is supplied with all Markes’ systems. Replacement check-standards are available in packs of 10.

  • Material emissions check-standards contain a range of polar and non-polar VOCs ranging in volatility from n-hexane to n-hexadecane at a nominal loading of 100 ng for each component. They enhance validation and quality control for service and manufacturing labs using TD–GC(–MS) to test chemical emissions from products and materials.
