Product Introduction
Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer. Headspace analysis requires that the compounds of interest have high volatility, while the rest ofthe sample is much less or non-volatile. The technique lends itself nicely as a substitute for labor-intensive extractions when the sample types are solids, viscous liquids, blood, or medications, for example.
Key Features：
Fully automatic system，you just need one click to complete all samples injection analysis.
Stable and reliable servomotors drive and software control systems.
Fault alarm and reminder function, which facilitates handling of problems encountered during analysis.
Advanced touch screen control, rich interface information and easy to operate.
The combination of six-way valve and sample loop minimizes dead volume and ensures injection accuracy.
Based on the heating cycle of sampler and the analysis cycle, intelligently calculate the overlapping heating vial loading time to improve efficiency.
All methods can be editing, storing and calling at any time. Press the run button to automatically complete sample analysis.
Start GC/GCMS synchronously or started by GC/GCMS, that could be improving efficiency and reducing sample waste.
Support for time progressive Mode Valve system and inert pipeline system can be heated at high temperatures, which make no residue.
The connection between the valve and pipeline is located in the heating box, without cold points, which be ensuring the integrity of the sample and excellent peak separation.
Supports multiple injection modes.
Sample loop balance time can be set.
Automatic leak detection and labeling of vial to avoid data distortion.
Automated addition of an internal standard to the focusing trap or to a tube.
Shake mode reduces balance time, improves sensitivity and repeatability.
Electronic Pressure/Flow (EPC/EFC) Control system.
PC end software can control instruments, collect status, save record logs, and track later.
