GC chromatography system BK-GC7820N

for gas analysisfor researchFID

Overview
The BK-GC7820N gas chromatograph by BIOBASE uses mechanical-valve gas routing and a high-precision pressure sensor to display gas path pressure and carrier flow in real time. Its three-chamber, large-column oven design increases expandability and supports multiple detector configurations (up to three simultaneously). Integrated chromatography processing software enables batch processing, customizable report templates and export to Excel, Word and PDF.
