  • Critical Leak Requirements in GC/MS, LC/MS and Analytical Instruments (.pdf)
    Gas Chromatography/Mass Spectrometry (GC/MS) and Liquid Chromatography/Mass Spectrometry (LC/MS) are analytical techniques used for chemical analysis. The properties of a sample are first separated using chromatography and then identified with the mass spectrometer. The equipment used
  • Comprehensive Analysis of Persistent Organic Pollutants in Complex Matrices Using GC with High-Performance TOF-MS
    interferences as well as variation. among technicians. Here we demonstrate a procedure that incorporates. a QuEChERS extraction, cartridge solid-phase extraction. (cSPE) cleanup and gas chromatography-time-of-flight mass spectrometry. (GC-TOFMS), resulting in good recoveries for a wide range
  • Anesthesia Contaminants
    This application note describes the analysis an anesthetic agent by gas chromatography-mass spectroscopy (GC-MS) to quantitatively determine the concentration of a suspected contaminant or impurity.
  • Quantification of Plasticizers in Plastics
    This application note describes a test method developed at CPG for the identification and quantification of plasticizer in PVC by gas chromatography/mass spectrometry (GC/MS). For a sample mass of 5-10g, the uncertainty in determining the percent plasticizer content is typically less than 1%.
  • MICRO: Ultrapure Fluids by Anurag Kumar (Jan 2000)
    and identify them. In this new method, water samples are passed through an adsorbent tube, the water is removed, and the compounds are analyzed by thermal desorption gas chromatography mass spectrometry (TD-GC-MS). Unlike existing techniques, this process does not use any organic solvents for extraction
