main features
1、 Stable and reliable column box system
1. The first-order program temperature can be manually controlled to meet different analysis needs.
2. Overheating protection function: When the temperature of the column box exceeds 420 ℃, the power will be automatically cut off
2、 Flexible sampler system
1. Fill column sampler, install packed column to meet daily chromatographic analysis work
2. Large caliber capillary column sampler for complex sample analysis
3. Gas injection valve: specifically designed for the analysis of gas samples
4. The glass column system is particularly suitable for pesticide analysis
5. Sample injector overheat protection: automatically cuts off power supply if temperature is abnormal
3、 Simultaneously install FID and TCD detectors
4、 File storage function
1. Users can save/read commonly used settings such as aging, secure shutdown, and similar analysis as needed
2. Storage of 6 analysis condition parameters
