This GC is of significance for providing data for calculating physical properties of the sample, such as heating value and relative density, or for monitoring the concentrations of one or more of the components in a mixture.
KN-1945 GC for Analysis of Natural Gas
Introduction:
Components in a representative sample are physically separated by gas chromatography (GC) and compared to calibration data obtained under identical operating conditions from a reference standard mixture of known composition. The numerous heavy-end components of a sample can be grouped into irregular peaks by reversing the direction of the carrier gas through the column at such time as to group the heavy ends either as C5 and heavier, C6 and heavier, or C7 and heavier. The composition of the sample is calculated by comparing either the peak heights, or the peak areas, or both, with the corresponding values obtained with the reference standard.
Introduction:
KN-1945 GC for Analysis of Natural Gas conforms to ASTM D1945 Standard Test Method for Analysis of Natural Gas by Gas Chromatography. It can analyze the chemical composition of natural gases and similar gaseous mixtures.
