GC112A is a universal gas chromatograph with microcomputerization, high performance, low price, and a new design. It features high stability, reliability, simple and reasonable structure, convenient operation, and an attractive appearance.
This manual describes the GC112A gas chromatograph, a micro‑computer‑controlled, high‑performance instrument for trace analysis. It covers technical specifications, system components, detector options, and safety requirements.
The document is organized into sections on the instrument overview, temperature controller, detector systems, installation and operation, capillary‑column analysis, routine maintenance, and the optional TCD detector with constant‑current power supply. Detailed procedures for column and detector installation, as well as troubleshooting guides, are included. This manual is written in Chinese.
| Column oven temperature range | 7 °C to 400 °C |
|---|---|
| Temperature control precision | ±0.1 °C (measured at 200 °C) |
| Maximum power consumption | ≤ 2000 W |
| Power supply voltage | ~220 V ± 22 V, 50 Hz ± 0.5 Hz |
| Independent temperature zones | 5 |
| Supported detectors (simultaneous) | Up to 3 (FID, TCD, ECD) |
It needs a ~220 V ± 22 V AC supply at 50 Hz ± 0.5 Hz.
The oven provides five independent temperature zones.
The temperature can be controlled to better than ±0.1 °C (measured at 200 °C).
Up to three detectors such as FID, TCD, or ECD can be installed simultaneously.
