Shanghai headspace sampler manufacturer

Shanghai headspace samplerThe principle:

A headspace gas chromatograph is an instrument that combines a chromatograph with a headspace sampler, by adding a headspace injection device in front of the gas chromatograph injection port. It uses the heated equilibrium of the tested sample (gas-liquid and gas-solid), and takes the volatile gas portion to enter the gas chromatograph for analysis. It is used for analyzing volatile trace components, such as detecting many volatile organic solvent samples such as methanol and ethanol.

Quantitative accuracy, high sensitivity. The sampling pump is matched with the injection valve for negative pressure sampling, with precise quantification and high sensitivity.

The temperature of the injection valve and sample transfer pipeline can be set to avoid sample condensation

Sampling pipeline and injection valve quantitative tube with blowback function to prevent cross contamination

Good compatibility and can connect to various models of gas chromatographs both domestically and internationally.

Microcomputer control, easy to operate, membrane keyboard for inputting parameter values, and with the function of synchronously starting data processing software

Automatic leak detection ensures that each injection bottle is leak free before analysis, without loss of precision or sensitivity

The alternative carrier gas option uses hydrogen as the carrier gas to ensure safe work and reduce laboratory costs

Priority sample positions can add important samples that arrive late in the sequence without the need to stop and restart

Pressure compensation always provides higher precision regardless of changes in laboratory pressure; Maintain the consistency of results between daytime and different laboratories

Application areas of headspace sampler:

Forensic Science: Testing for volatile toxins such as alcohols, aldehydes, and ketones in blood and urine.

Traffic safety: Testing the blood alcohol content of vehicle drivers when drinking or driving under the influence of alcohol.

Brewing industry: determination of low boiling point aroma components in beer.

Food industry: detection of solvent residues in extracted oil.

Environmental protection: determination of volatile halogenated hydrocarbons in surface water and tap water such as rivers, lakes, etc.

Pharmaceutical industry: detection of residual solvents in drugs.

Material control: detection of residual acetaldehyde in beverage bottles.
