A01 - GC9800 Gas Chromatography
|
Descriptions
GC9800 series gas chromatography is a kind of practical
analytical instrument with high performance
which allows assembly of highly sensitive thermal conductivity detector (TCD)
or highly stable hydrogen
flame ionization detector (FID). According to the user’s needs, different
detectors such as MTCD, ECD, and
so on, can also be installed in this instrument. The design and fabrication
of this instrument are based on the
principle of gas chromatography. It has reasonable structure, high
sensitivity, and it is easy for operation and
maintenance. |
 |
When operating GC9800, a certain kind of carrier gas (H2, N2, or Ar, which
is called mobile phase) is
needed. And the stationary phase is filled in the chromatographic column.
The compositions of analyzed
mixture are separated by multiple distributions between two phases or
because of the difference of bulk
additive absorbability they are separated to different compositions. The
single composition after
chromatographic fractionation enters detector along with the carrier gas one
after another. Then the
corresponding electric signals will appear in the detector and be recorded
with chromatographic data
processor or chromatographic working station. Thus qualitative or
quantitative analysis can be carried to each
composition in mixture.
The instrument can be equipped with different sampling devices and it can be
used to analyze gas, liquid
and solid samples. In addition, GC9800 can make macro-analysis and
micro-analysis for various gases and
organic mixtures whose boiling point is below 350ºC. GC9800 is an
indispensable analytical instrument in
the fields of petroleum, chemical industry, spice, medicine, hygiene,
metallurgy, electric power, gas industry
and many specific domains.
