General Specifications Model GC1000 Mark II Process Gas Chromatograph 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. n 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. n 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. n 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. n 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. n 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. n 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. n 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.
