Agilent 7890A GC with G1888 Headspace Sampler Overview
The Agilent 7890A Gas Chromatograph (GC) paired with the G1888 Headspace Autosampler, configured with a single Flame Ionization Detector (FID) and Split/Splitless (SSL) inlet, is a robust and highly reliable solution for the analysis of volatile compounds in complex sample matrices. This system is specifically designed for headspace gas chromatography applications, enabling accurate and reproducible measurement of volatile organic compounds (VOCs) without direct sample injection. The G1888 Headspace Sampler automates vial pressurization, equilibration, and sample transfer, reducing contamination risk while improving repeatability and throughput.
The 7890A GC platform provides stable temperature control, precise Electronic Pneumatic Control (EPC), and consistent chromatographic performance. The integrated FID detector delivers high sensitivity for hydrocarbons, offering a wide dynamic range ideal for trace-level and high-concentration analysis. This configuration is widely used in industries such as pharmaceuticals, environmental testing, food and beverage, and forensic analysis, where reliable headspace sampling is essential for volatile compound detection.
Agilent 7890A GC with G1888 Headspace Sampler is offered fully refurbished and tested, in working condition.
