TP-6100 automatic headspace sampler Introduction
The headspace sampler is an excellent sample pretreatment device for gas chromatographs. For a large number of samples containing low boiling point components, the results cannot be directly injected into the sample, and the sample is placed in the headspace bottle and sealed. The temperature is volatilized and concentrated at the top of the bottle. Through the analysis of the gas phase at the top of the bottle to achieve qualitative and quantitative purposes, this headspace gas chromatography method and technology has become an important and widely used means.
TP-6100 automatic headspace sampler is a new product with unique technology and independent intellectual property rights newly launched by our company on the basis of the original TP-6100A. Compared with domestic similar products, it has more working holes and can achieve balance method and addition. Two modes of operation, the unique design of the product has obtained a utility model patent. Features
1.Highly versatile, the headspace sampler flow path system is novel and unique in design, with balanced injection and pressurized injection. It is very convenient to be used with domestic and imported gas chromatographs. .
2.It adopts single-chip microcomputer control, LCD large-screen display, and human-machine dialogue mode. It is extremely simple and convenient to use and very flexible.
3.Intelligent programming, one-click sampling, injection, analysis, and backflushing.
4.Efficient, fast and safe, the heating block in the sample bottle heating furnace adopts the overall circular opening structure, and the over-temperature and temperature-off protection device is designed. It has high power, fast heating, small gradient and high temperature control precision. Features such as warming up and safety.
5.High analytical efficiency. In order to improve the analysis efficiency, the sample transfer line and the injection valve are independently designed with heating, temperature control and heat preservation to avoid condensation of the sample during transmission.
6.The sample transfer line and the injection valve are equipped with an automatic backflush function to avoid cross contamination of different samples.
7.Can store more than 10 sets of methods for storage and recall during operation
8.Variety of bottle holders, designed for the user to design a sample metal bottle body, providing users with a variety of sample bottle specifications.
9.The TP-6000 headspace sampler is a time-controlled injection, while the TP-6000A headspace sampler is used for quantitative volumetric injection. The tube can be selected as required. Technical Parameters
