ABB PGC2000 series E2 process gas chromatograph

ABB PGC2000 series E2 process gas chromatograph

Product positioning and development history

Background: ABB launched the world's first online process gas chromatograph in 1957, which was upgraded to PGC2000 series version two (E2) in the early 21st century. As the second generation product of Vista 2000, it set new standards in performance, reliability, and operability.

Model classification: including 9 models such as basic type, process distillation analyzer, PNA analyzer, and program-controlled temperature chromatograph, covering scenarios such as petrochemical and fuel analysis.

Controller: Industrial microprocessor using real-time embedded operating system to ensure real-time data processing and system recovery capability.

Column box and gas path: precise temperature control of air bath analysis column box to improve chromatographic separation efficiency; PFA Teflon ®  Enhance flexibility of pipelines and reduce maintenance; The liquid/gas injection valve is compatible with different samples.

Analysis valve:

791 micro liquid sampling valve: resistant to high pressure (197.28 KPI), high temperature (200 ℃), integrated vaporizer and passivation device.

M2CP sliding plate valve: automatic wear compensation, low maintenance cost, supports packed column/capillary column.

DV-22 diaphragm valve: suitable for fast column cutting technology, capable of withstanding 300 PSI pressure.

Chromatographic column technology

Core components, using high surface area support and high-purity fixative to ensure separation efficiency; Optional packed column, micro packed column, capillary column, suitable for different analysis needs.

Performance and detection capability

control function 

Electronic Pressure Control (EPC): 5 independent control zones, resistant to environmental interference, supporting program voltage transformation.

Digital Temperature Control (DTC): 5 temperature zones, supports program temperature variation, with higher accuracy than analog controllers.

Detector Type

Thermal conductivity detector (TCD): universal type, measuring range covering volume/mole/weight percentage, supporting low ppm measurement.

Flame ionization detector (FID): high sensitivity, suitable for ppm/ppb level hydrocarbons, automatic ignition and shutdown alarm.

Flame photometric detector (FPD): sulfur selective detection, sensitivity increased by 200 times compared to conventional, PMT thermoelectric cooling reduces noise.

New detectors: dielectric barrier discharge ionization detector (DBDD) and photoionization detector (PID), designed for ppb level measurement of high-purity gas impurities, halogenated hydrocarbons, etc.
