  • AccuTOF TM GC Product Brochure
    high-sensitivity analysis of ultra-trace components by spectrum measurements. _Identification of unknown components - Accurate mass measurement facilitates identification of unknown components. _High-resolution mass chromatogram - High-resolution mass chromatogram allows for tracecomponent analysis. _GC
  • PAS vs. GC for SF6 Monitoring
    were gathered and tested on both the Photoacoustic Unit and the GC. The test results are shown below:
  • Industrial Hygiene Monitoring with a Portable GC
    is insufficient. Since ppt levels are generally below the detection limit of most GC's, a concentration technique is necessary. Solid sorbents such as tenax or graphitized carbon which can be thermally cycled are more popular for indoor air pollution studies since the entire sample is injected
  • Features and Applications of Newly-Developed GC-TOFMS
    A gas-chromatograph mass spectrometer (GC-MS) is a combined analyzer that has superior ability in analyzing organic compounds qualitatively and quantitatively. The first part, gas chromatograph, separates the compounds included in a sample (mixture), then the second part, mass spectrometer, obtains
  • Recent Improvements in Process GC Instrumentation (.pdf)
    This paper discusses the recent improvements in process GC instrumentation focusing on three areas of monitoring interest: ppb Levels of BTX in beverage grade CO2, Detection of VOCs under Texas Chapter 115 and Sparging/Headspace System for On-line Analysis of Total or Speciated. The process GC now
  • The Effects of Hydrogen Purity on GC Analysis and Column Life
    Hydrogen has been widely adopted as a carrier gas to replace nitrogen and helium in GC applications for a variety of reasons. Superior advantages include faster analysis, lower cost and the reliability of supply that hydrogen (generated on-site) offers. The purity of carrier gas is crucial
  • Comparison of Various Headspace Septa Using GC Analysis
    " bleed product. In the meantime, however,. special methods can be used to drive bleed to more acceptable levels. Headspace analysis is particularly affected by septum bleed. This study evaluates three readily available headspace. septa using GC analysis. Each of the samples are made of silicone
