Introduction: VOC monitoring in the atmospheric environment and indoor air is an important part of my country’s ecological environment protection. At present, the country has formulated a series of VOC testing standards, such as environmental standards HJ734-2014, HJ644-2013, HJ583-2010; indoor air standards GB/T18883- 2002, GB50325-2010 and the standard HJ/400-2007 for volatile organic compounds in cars. To do a good job of VOC detection, from sample collection to experimental data analysis, every link is very important. In these links, the step of preparing the standard sample tube is particularly critical. TSP-600 adsorption tube standard equipment, it is a high-tech product specially developed for preparing standard sample tubes. It has independent intellectual property rights. It can prepare 6 standard sample tubes at the same time. The patented quartz vaporization chamber design makes the standard liquid Fully vaporized, higher adsorption efficiency, good linearity and reproducibility, the preparation time of 6 standard sample tubes is less than 10 minutes, which improves the efficiency of preparation of standard sample tubes for laboratory operators. Application areas: environmental monitoring, occupational health, quality inspection institutes, immigration, architectural sciences, metrology institutes, universities and scientific research institutions, third-party inspections and automobile inspection industries, etc. Technical features: 1. 6 standard sample adsorption tubes can be prepared at the same time; 2. The patented quartz vaporization chamber ensures that the standard liquid sample is fully vaporized, and the adsorption efficiency is higher; 3. Each sample tube position is equipped with an independent quartz vaporization chamber; 4. The temperature of the quartz vaporization chamber can be adjusted, and the temperature range is from room temperature to 400°C; 5. Using needle valve flow control technology, the carrier gas flow of each sample tube position can be adjusted; 6. The operation is simple, just inject the standard solution into the corresponding inlet to complete the preparation of the adsorption tube standard sample; 7. The inlet adopts high temperature resistant non-adhesive imported septum; 8. The linearity of benzene is better than 0.999, and the reproducibility RSD is less than 3%; 9. Time to prepare 6 standard sample tubes <10min; 10. The volume is small and exquisite, it can be placed on a laboratory bench or a fume hood.
