The GC112A gas chromatograph is a new design of general gas chromatograph with microcomputer, high performance, low price, high stability, reasonable structure, convenient operation and beautiful appearance. The instrument has a wide range of applications, and is suitable for gas analysis in the fields of petroleum, chemical industry, medicine, environmental protection, etc.
The manual describes the GC112A gas chromatograph, a micro‑computer‑controlled, high‑performance instrument with a temperature range up to 400 °C and five independent temperature zones. It outlines technical specifications, optional accessories, and the principle of operation.
Detailed sections cover the microcomputer temperature controller, detector systems (FID, TCD, ECD), installation of gas lines, capillary‑column analysis, routine maintenance, and the GC112A‑TCD thermal conductivity detector with its constant‑current power supply. This manual is written in Chinese.
| Column oven temperature range | 7 °C – 400 °C |
|---|---|
| Temperature control precision | ±0.1 °C |
| Maximum temperature | 400 °C |
| Power supply voltage | ~220 V ± 22 V, 50 Hz ± 0.5 Hz |
| Maximum power consumption | ≤ 2000 W |
| Number of independent temperature zones | 5 |
| Programmed temperature ramp rate | 0.1 °C – 40 °C/min |
It requires a ~220 V ± 22 V, 50 Hz ± 0.5 Hz power supply and consumes no more than 2000 W.
The instrument provides five independent temperature control zones.
The GC112A can accommodate up to three detectors, such as a hydrogen flame ionization detector (FID), a thermal conductivity detector (TCD), and an electron capture detector (ECD).
The column oven can be set from 7 °C up to 400 °C.
