Performance characteristics:

Based on the new generation high-performance and high stability GC-7900 gas chromatograph, it operates reliably and stably.

◆ Wide applicability, can be used for various types of gas analysis.

◆ Adopting a multidimensional chromatography system, it can drive up to 6 injection or cutting valves, and install n packed columns or capillary columns as needed.

Injection method: Valves can be connected in series for injection or injected separately, which can achieve split injection without splitting.

Detector: thermal conductivity detector, hydrogen flame detector, flame photometric detector, and installation of conversion furnace. It can be used in series or separately.

◆ Equipped with 4/8 liter aluminum bottles for multi-component standard mixed gas or single component gas.

◆ Dual channel chromatography workstation, supporting Windows XP operating system, allows for free storage, data processing, and report printing of chromatographic analysis spectra.

◆ It can be equipped with a natural gas analysis chromatography workstation, which can calculate technical parameters such as natural gas calorific value, white number, relative density, compressibility factor, etc.

◆ Can achieve online automatic analysis,By laying pipesroadThe instrument canAutomatically sampling on a periodic basis and monitoring the process sample gas without interruptionAutomatic calibration, no need for manual verification.piperoadIn areas where the probe has not been installed, manual sampling and testing can be used, which is flexible and reliable.
