  • How to Convert from Helium to Hydrogen as a Carrier Gas in Gas Chromatography (.pdf)
    This How to Guide will take you though the steps necessary to convert from Helium to Hydrogen as a carrier gas for Gas Chromatography. The use of Hydrogen from an inhouse >generator will lead to considerable benefits in cost, safety and convenience in the laboratory
  • Chromatography Instruments
    of chromatography. Chromatography instruments can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Gas chromatography is a technique used to separate volatile organic compounds. Gas chromatography columns (GC columns) are of two types: packed and capillary
  • Introduction to Gas Chromatography
    Analytical chemists that wish to perform qualitative and quantitative analysis on samples are often faced with situations that require separation of the compound(s) of interest from the bulk sample. While some types of analysis do not require this separation, many do. There are several methods
  • Texas Instruments: Novel Separation Technique for the Analysis of Trace Levels of Atmospheric Contaminants in Inert Semiconductor Process Gases
    Low ppb detection limits for contamination in cylinder gases have been achieved with gas chromatography using a modified gas injection system and megabore capillary columns with a variety of detectors including mass spectrometry, atomic emissions, and discharge ionization. Components of interest
  • Selecting Makeup Gas for GC with FID (.pdf)
    When gas chromatography is employed for the detection of trace compounds, the characteristics of the carrier gas used for the actual separation and the gas used for detection may be significantly different. As an example, the carrier gas flow rate is selected to provide optimum resolution
  • How are CNTs Purified?
    "Purification of CNTs generally refers to the separation of CNTs from other entities, such as carbon nanoparticles, amorphous carbon, residual catalyst, and other unwanted species. The classical chemical techniques for purification (such as filtering, chromatography, and centrifugation) have been
  • MICRO: Extreme Silicon - Sun (March 2000)
    Fourier transform infrared spectroscopy, ion mobility spectrometry, time-of-flight ion mass spectrometry, x-ray photoelectron spectroscopy, and thermal desorption gas chromatography mass spectrometry. However, all these methods have limitations. They either lack the capability to identify specific
  • MICRO: Extreme Silicon - Sun (March 2000)
    gas chromatography mass spectrometry. However, all these methods have limitations. They either lack the capability to identify specific contaminants or are unable to quantify total organics accurately. This article describes a new technique that uses thermal desorption gas chromatography (TD-GC
