1) The GCMS (Gas Chromatograph
Mass Spectrometer) system must have both the gas chromatograph
and the mass spectrometer supplied by the same vendor.
A gas chromatograph
that is capable of calculating the HCDP at any pressure enables a very useful operational diagnostic that can be used to avoid two-phase flow, and therefore incorrect measurement.
Yet so far, the surface compounds identified by the gas chromatograph
are the same as those detected in the upper atmosphere, which had been characterized by an infrared spectrometer on the orbiting Cassini spacecraft.
Breaking a 50-year technology barrier, the GCX is the first field-mountable industrial gas chromatograph
transmitter that offers the features of traditional process gas chromatographs
Of the compounds identified by GC/MS analysis, those available as pure compounds or ready-made standards were run as calibration standards on a capillary column gas chromatograph
with a flame ionization detector (GC/FID).
To manage data, quality control departments in the pharmaceutical industry increasingly need to integrate the data from multiple chromatographs
used in their laboratories.
Siemens Bartlesville facility, employing approximately 160 people, is the global "Center of Competence" for the process gas chromatograph
Contract notice: Delivery and installation of gas chromatographs
The sample fills a fixed volume sample loop that is injected into the chromatograph
Competitive Structure Process Chromatograph
The unit has been adapted to fit inside of a high-temperature chromatograph
in order to determine the absolute masses of samples which are only soluble at elevated temperatures.
To decode the marker, scientists would separate the constituent compounds with a gas chromatograph
and then break each compound apart with a mass spectrometer to reveal the particular combinations of isotopes.
