Model GC1000 Mark II
Process Gas Chromatograph

GS 11B03A03-01E

ntGENERAL

A Gas Chromatograph analyzes a gas or volatile
liquid sample by separating components for detection.
The discrete separation and positive identification of
components and measurement of the composition
with no interference is a positive advantage of the gas
chromatograph. Making good use of this advantage,
the process gas chromatograph is widely used in
many industries.
YOKOGAWA manufactures two models of GC1000
Process Gas Chromatographs: the GC1000E/C/
S (isothermal oven type) and the GC1000T/W/D
(programmed temperature type). The GC1000E/
C/S can analyze gas and liquid samples from
room temperature up to elevated temperatures
corresponding to their boiling points. The GC1000T/
W/D is capable of performing high resolution analysis
by using capillary columns similar to laboratory gas
chromatograph.

ntFEATURES

GC1000 MarkII

nt Capabilities of analyzing PIONA and the
Distillation points
Techniques for laboratory analyses can also be utilized
in the GC1000 series by configuring and installation of
high resolution capillary columns. This allows for the
analysis of properties such as PIONA and Distillation
points.
nt Capability of analyzing high boiling point liquid
samples
The liquid sampling valve with vaporizer having a
tight seal provides highly accurate liquid sampling.
The liquid sample is vaporized by an internal heater
and introduced to the columns. This allows for highly
consistent sample volume and excellent reproducibility.
nt Capability of analyzing samples in a very wide
range of boiling points
In the thermostatic oven, temperature is accurately
controlled within +/- 0.03°C by an air-bath and
circulation fan. For wide boiling point range samples,
the programmed temperature oven enables the
GC1000 to analyze these samples with high resolution.
nt Easy operation via User Friendly Displays
User friendly keyboard and display allows easy
operation and display of analysis data. Many functions
can easily be accessed to the user including auto gate
tracking, column end-of-life warning and auto gain
setting.
nt Enhanced maintenance using PC operation
With our maintenance terminal software (GCMT/
ASMT), the GC1000 can be operated from remote
location like the control room or office. In addition, the
analyzer bus allows for total maintenance management
system to include other field analyzers and data
acquisition capabilities.

nt Achievement of High Sensitivity TCD
Most analysis which normally requires FID detector
can now be done using the new high sensitivity TCD
detector.
This eliminates the requirement of fuel gas and
presence of flame as in the FID.
nt Expectation of the effective result by EPC
EPC (Electronic Pressure Control) controls the utility
gas pressure by electronics and software, providing the
same efficiency as programmed temperature analysis.

Examples of Applications in Industries
