Product Description

GC-7890-DL Gas Chromatography Insulating Oil DGA Dissolved Gas Content Analyzer


 

About the analysis of dissolved gases in transformer oil: hydrogen (H2), oxygen (O2), nitrogen (N2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ethylene (C2H4), ethane (C2H6), acetylene (C2H2).

 

Introduction

 

1) GC-7890-DL Gas Chromatography Insulating Oil DGA Dissolved Gas Content Analyzer is an effective means to achieve gas chromatography. Gas chromatography with a high-performance high selectivity, high sensitivity, rapid analysis, small sample volume, wide range of applications and so on. Chromatography can be widely used systems and scientific research institutes and universities in areas such as health and epidemic prevention, environmental monitoring, quality supervision, petrochemical, pharmaceutical, commodity inspection, public security, food, electricity, liquor, mines and so on.
 

2) GC-7890-DL Gas Chromatography Insulating Oil DGA Dissolved Gas Content Analyzer is controlled by a microcomputer, a higher cost performance of the gas chromatograph, can be equipped with a thermal conductivity detector (TCD), flame ionization detector (FID). Can be installed packed column and capillary column oven can be heated and temperature-programmed operations.
