AutoTP-93Fully automatic blowing and capturing deviceIt is a 93 bit device with an electronic cold trap40mlVOASample bottleFully automatic blowing and capturing device. Using a high sugar injection pump for sampling, helium/nitrogen gas is used as the purge gas, and the purge tube is introduced into the sample solution for bubbling; Under continuous airflow blowing, volatile components in the sample escape with the blowing gas and are concentrated by a capture device equipped with an adsorbent; After a certain blowing time, turn off the blowing gas, switch the six way valve to connect the capture tube to the carrier gas path of the GC, and quickly heat the capture tube to decompose and absorb the captured sample group before entering the GC for analysis with the carrier gas. By combining with GC or GC/MS, it can be widely applied in environmental analysis, such as the analysis of organic pollutants in drinking water or wastewater, as well as the analysis of volatile compounds (such as odor components) in food.
