Description of the characteristics of the chromatograph-specific headspace sampler

Features of Chromatography-specific Headspace Sampler

The headspace sampler analysis methods are as follows:

First, manual mode (oven or water bath method) Manual Injection

1) The sample reaches thermal equilibrium after heating

2) Take the sample out with a syringe

3) quickly get the gas phase on the injection analysis

Second, the gas tight needle injection method Gas-Tight Syringe Injection

1) The sample reaches thermal equilibrium after heating

2) Extract the sample by a heatable gas tight needle

3) Move to gas phase injection analysis

Balanced-Pressure System

1) The sample reaches thermal equilibrium after heating

2) Using a conduit to pressurize the carrier gas

3) Samples are injected with carrier gas

Fourth, the quantitative ring pressure system Pressure-Loop System

1) The sample reaches thermal equilibrium after heating

2) Pressurize the sample into the loop

3) The valve will drive the sample into the transmission channel to inject

Five, static - dynamic compensation - AutoHS headspace sampler

5.1. The patented technology provides more means for sample extraction.

5.1.2, purge mode

5.1.3, constant mode

5.1.4, multiple headspace modes

5.1.5, temperature progressive mode

The headspace analysis method has five types of injection methods: manual mode, gas tight needle injection method, balanced pressure system, loop pressure system, and static-dynamic compensation.
