Gas Chromatograph

Order Id: CH-GC6891N
Categories: Chromatography  Gas Chromatography 

Instrument Introduction

A brand new generation of high-end laboratory gas chromatograph --GC 6891N, the integration of the Nanjing Branch McNair innovative technology, based on the most advanced technology platform and decades of international industry technology experience, functionality, reliability and flexible application of and other aspects are the leading position in the industry.

GC 6891N has a reliable international procurement of components specially designed hardware integration and stable software. High-quality hardware, intelligent operation and data processing software can meet their repeatability and convenience in long-term measurement. Both in manufacturing precision and in technical performance aspects, there is subversive breakthrough.

Application: forensic analysis and detection of oil exploration and refining, petrochemicals, fine chemicals, food safety, environmental protection, electronic high-purity gas industry, legal medical experts of public security and national security and other areas.
