Overview

It can be widely applied in various analytical fields such as petrochemicals, fine chemicals, pharmaceuticals, environmental monitoring, food hygiene, high-purity gases, electricity, brewing, forensic identification, scientific research, and education.

Product Details

Full Chinese interface, intuitive and simple operation of gas chromatograph. The interface is entirely in Chinese, and the instrument's setting prompts adopt a graphical human-machine dialogue method, allowing for the setting of analysis conditions in a short period of time.

The TVOC analysis specific gas chromatograph is a new type of gas chromatograph with independent intellectual property rights, developed based on years of gas chromatography manufacturing experience and advanced manufacturing technology at home and abroad, combined with domestic application fields and actual user usage.

The TVOC analysis specific gas chromatograph has outstanding characteristics, easy operation, stable and reliable performance, high test data accuracy, strong functionality, and superior cost-effectiveness. It can be widely applied in various analytical fields such as petrochemicals, fine chemicals, pharmaceuticals, environmental monitoring, food hygiene, high-purity gases, electricity, brewing, forensic identification, scientific research, and education.

Full Chinese interface, intuitive and simple operation of gas chromatograph

The interface is entirely in Chinese, and the instrument's setting prompts adopt a graphical human-machine dialogue method, allowing for the setting of analysis conditions in a short period of time.

High precision and wide range column box temperature control

Microcomputer based temperature control, high temperature control accuracy, stable and reliable. Equipped with a six channel fully independent temperature control system, the column box can achieve five stage programmed temperature rise; Equipped with an automatic rear door structure, it can be controlled near room temperature and has a fast temperature rise and fall speed.

Simultaneously save ten sets of analysis parameters

Save ten sets of analysis parameters through file format, which can be saved for a long time in the event of power failure; And it can call, initialize, and save files.

Multiple design options to meet different analysis needs simultaneously

The instrument has dual columns and dual gas paths, and can be equipped with three injectors and two detectors: hydrogen flame and thermal conductivity; Dual hydrogen flame or dual thermal conductivity can also be installed simultaneously. It can easily achieve the conversion between packed column injection, direct injection into large-diameter capillary columns, and split injection into small-diameter capillary columns. According to the analysis needs, optional split/non split injectors, gas injection valves, converters, crackers, headspace injectors, pyrolysis gas intakes, etc. can be selected.

High performance detector

*Flame Ionization Detector (FID) - a standard detector for high-sensitivity analysis of organic compounds.

*Thermal conductivity detector (TCD) - a universal detector for analyzing permanent gases and low-carbon organic compounds.

scalability

Instrument expandable optional detectors: Electronic Capture Detector (ECD), Flame Luminescence Detector (FPD)

The instrument can be expanded with optional electronic mass flow meters (EPC)

Can be modified into various specialized chromatographs according to user requirements
