Headspace injection technique is aÂ convenient sample pretreatment processing for gas chromatography. It's adapted for volatile component analysis. The principle is putting theÂ
sample which is under test to aÂ pressure-tight container, andÂ separateÂ the volatile components from sample through heating-up, reaching balance in gas liquid (or gas solidÂ
)Â phase, and then extract the top gas to analyze the volatile components and content in sample.
ItÂ canÂ avoid complicated sample pretreatment processing,Â also can avoid the interference to analysis from organic solvents.Â Reducing the injection inlet pollutant for the gas chramography. ItÂ and can beÂ compatible with all kinds of gas chromatography both here and aboard.
1. Sampling pump cooperate with sampling valve, negative pressure sampling, precision quantitative, high sensibility.
2. Sampling valve and sample transfer line can set temperature, to avoid sample condensation.
3. Anti-blowÂ functionÂ for the samplingÂ pipelineÂ and sampling valve, to avoidÂ cross contamination.
4. Good compatibility, can beÂ compatibleÂ with all kinds of gas chromatography both here and aboard.Â
5. Micro-computer control, easy to operate, with membrane keyboard, has the function of data processing starting synchronously.

The Crane rail is what guides a crane to travel the pre-designated route while transferring pressure energy coming from wheels to the foundation where rail is built. It mainly comes in three types: heavy, light, and specialized.
Maximum load bearing capacity:120t
Light weight and high precision
Smooth rail surface reduces resistance to the moving object.
shaped cross-section helps with great bend strength.
Improved wheel-to-rail contact condition allows for higher load bearing capacity of crane.
Smooth operation reduces the risk of impact.
ApplicationsMachining, wind power, automobile, papermaking, steel, material handling, metallurgical,
and petrochemical industries.
