The 300ml/min high-purity nitrogen generator is professional supporting gas supply equipment specially developed for gas chromatograph (GC) laboratory analysis, and its core performance parameters are fully optimized and matched according to the gas consumption and gas quality requirements of conventional gas chromatographs. The rated stable flow of 300ml/min is the optimal matching flow for most desktop gas chromatographs, which can perfectly meet the carrier gas and auxiliary gas supply demands of chromatographic separation and detection. The equipment realizes constant flow output through a high-precision mass flow controller, with flow control accuracy up to ±0.5%FS, effectively avoiding baseline drift, peak distortion and analysis error of chromatographic detection caused by gas flow instability.

In terms of gas purity, this special nitrogen generator for gas chromatography can stably output high-purity nitrogen with a purity of 99.999%, and strictly control trace impurities that affect chromatographic detection. After multi-stage purification such as molecular sieve adsorption, catalytic deoxygenation and ultra-fine filtration, the residual oxygen content in output nitrogen is less than 1ppm, the dew point is lower than -55℃, and there is no oil, dust and organic impurities. Ultra-low impurity content effectively prevents the oxidation of chromatographic columns and detectors, prolongs the service life of chromatographic equipment, and ensures the accuracy and repeatability of trace component analysis data in sample detection.

The equipment has excellent operational stability and environmental adaptability, adopting intelligent constant pressure and constant flow control technology, with automatic start-stop and pressure maintenance functions. It can start quickly and reach the standard gas state in 20 seconds, realizing long-term stable gas supply for gas chromatograph continuous detection. The equipment is designed with low noise and low power consumption, with operating noise less than 40dB, which is suitable for quiet analytical laboratory environments. In addition, it is equipped with perfect fault self-detection and overpressure protection functions, which can automatically alarm and shut down in case of abnormal pressure and pipeline blockage, ensuring the safe and stable operation of gas chromatograph supporting detection work, and is the standard supporting equipment for conventional gas chromatograph laboratories.
