This manual introduces the basic structure and working principle of GC1120 gas chromatograph, as well as how to use GC1120 gas chromatograph for sample analysis.
The GC1120 is a computerized, high-performance, and low-cost gas chromatograph designed for general-purpose use in QA/QC, environmental analysis, clinical applications, and research. It features a microcomputer temperature control system with six separate zones reaching up to 400°C and supports up to three sample injectors. The instrument can accommodate six types of detectors, including Flame Ionization Detectors (FID) and Thermal Conductivity Detectors (TCD), with optional modules for capillary and packed columns.
| Column oven temperature range | 7℃above room temperature ~ 400℃ |
|---|---|
| Temperature control accuracy | better than ±0.1℃ @200 ℃ |
| Temperature programming stages | 7-stage temperature programming |
| Power supply | 220V±22V , 50Hz ±0.5Hz |
| FID Limit of detection | Dt≤8×10-12 g/s |
| TCD Sensitivity | ≥5000mV·ml/mg |
The maximum temperature for the column oven is 400℃.
The instrument can fit up to 6 kinds of detectors, including FID, TCD, ECD, FPD, NPD, and PID.
The ambient temperature should be between +5 ℃ and +35 ℃.
