Gas chromatograph BK-GC901
The BK-GC901 gas chromatograph features full electronic flow control (EPC) and complete computer-based instrument control; it can also be equipped with a high-precision automatic liquid sampler. It is widely used across various sectors—including the petroleum and chemical industries, environmental protection, food safety, disease control, education, and scientific research—enabling the analysis of macro-, micro-, and trace-level organic and inorganic substances, as well as gases.
