Features:
Headspace Samplers eliminate tedious and error-producing steps required in other GC sample preparation techniques, enabling you to extract more information
from your samples in less time. The intuitive touch screen graphical user interface provides easy control of the sampler. A patent device with dynamic and static
function extended the range of the headspace technology application.
An intuitive, color touch screen user interface provides instant access to system functionality. Set parameters, recall stored methods and start sampling quickly.
The modern screen graphical user interface displays a sampling process. And making user know well it.
- Leak Test：This function will help user to complete the whole carrier gas system test with a vial and get a high reliability.
The Double holes in needle and gas selecting provide dynamic and static headspace methods. Employed the technique prevent from sample decomposition or oxidization. Employing the Purge mode, can sweep the air in vials with carrier gas. The mode is useful in kinetic studies.
- High Sample Throughput ：Volatile compounds in almost any sample matrix can
be analyzed simply and quickly by headspace gas chromatography. Headspace sampling provides a method that extract sample of liquid and solid with a solvent-free and minimizes rework by eliminating many of the tedious and error-producing . The system completely rely on volatilization to separate the compounds from the sample matrix, so sample extraction, clean up and preconcentration are not necessary.
Constant and Purge Mode：Auto HS provides high sample throughput. Equipped with a 40-sample tray and 15 positions in the heating oven allowing unattended overnight operation for many applications. It can load 13 vials to be purged in the Purge Mode. In Constant Mode , automated constant heating time is employed with optimized sample overlapping for maximum sample throughput in the minimum amount of time. It can simultaneously thermostat up to 12 samples, ensuring that the next sample is always ready for analysis upon completion of the previous run. This adds up to a significant time savings since there is no need to wait for the next sample to heat and get best reproducibility. A deactivated sampling path, from switch valve to transfer line, is standard on the AutoHS. The clean gas swept the sample path.
Progressive Mode： In the Progressive Mode, the vials are thermostatted for an increasing time, representing a multiple of the first thermostatting time. It is used in the determination of the necessary equilibration time, where a number of vials containing the same sample are to be thermostated for increasing periods. Automatically optimized samples.
- MHE mode：The technique requires multiple extractions from the sample vial. This is very useful for developing method and running special sample.
- Input/Output Port：Provided ports to connect with any gas chromatograph with a standard interface. They includes: Ready In, Start In, Stop In, Ready Out and Run Out.
