Gas Chromatograph Analyzer BK-GC7820 (CAT#: STEM-OEM-0352-ZJF)

This gas chromatography system includes a 5.7-inch LCD display for real-time monitoring of temperature, time, and gas flow. It supports functions such as self-test, power protection, keyboard lock, automatic ignition, and anti-interference measures. It connects to the internet for automatic data transfer and upgrades. Equipped with a flame ionization detector (FID) by default, it also supports TCD, ECD, FPD, and NPD detectors, with simultaneous installation of up to three detectors. It accommodates both packed and capillary columns, offers double-column compensation to minimize noise and drift, and includes a spacious oven and powerful insulation. Comes with chromatography software for data processing.
