Gas Chromatograph

Product Description

The S7060 Gas Chromatograph is an analyzer dedicated to the detection of non-methane total hydrocarbons (NMHC) and benzene series. In addition to the standard separation and measurement systems inherent in conventional chromatographs, it is equipped with flexible touch-screen operation software and versatile measurement functions.

Adopting the high-temperature heat tracing dual-column parallel backflush chromatographic separation technology, the instrument can automatically measure and analyze the contents of methane, total hydrocarbons and benzene series. The content of non-methane total hydrocarbons is derived from the difference between the total hydrocarbon content and the methane content, which significantly shortens the analysis cycle.

Typical application fields include coating manufacturing, organic chemical industry, wire and cable manufacturing, tire manufacturing, petroleum cracking, semiconductor integrated manufacturing, garment manufacturing, pharmaceutical production, packaging and printing, etc.

Technical Advantages

The system is available for OEM.
Adopts EPC technology for carrier gas pressure control, featuring precise and stable pressure regulation with an accuracy better than ±0.1kPa.
Employs EFC technology for hydrogen and air flow control, with a flow control accuracy superior to 0.5% F.S.
Equipped with automatic ignition upon flameout; hydrogen supply will be cut off if ignition fails to ensure system safety. It also has over-temperature automatic protection function to prevent device damage.
The column oven temperature control accuracy is better than ±0.1℃.
Uses an ultra-long-life switching valve with stable switching gas flow and low maintenance requirements, ensuring reliable operation for more than 10 years.
Incorporates a miniaturized FID detector with an extremely low detection limit (0.01ppm), which offers ultra-high sensitivity, excellent reproducibility and high analysis efficiency for various organic waste gases such as total hydrocarbons, non-methane total hydrocarbons, ketones, alkenes, alcohols and benzenes.
