Jiangsu Province Environmental Monitoring category chromatography gas line installation

Many large-scale purchase of laboratory equipment needed to work high purity gases, gas species commonly used are: high purity nitrogen, high purity helium, high purity argon, high purity hydrogen, compressed air, methane, acetylene, etc. Gas Applications: 1. some gas and drive control for the equipment, pneumatic valve switch control, such as compressed air; 2. some carrier gas for gas analysis, such as chromatography and spectroscopy class equipment, frequently used equipment : gas chromatography (GC), liquid chromatography (HPLC), gas chromatography mass spectrometry (GC-MS), liquid chromatography mass spectrometry (HPLC -MS), inductively coupled plasma emission spectrometer (ICP- AES), inductively coupled plasma mass spectrometry (ICP-MS) and other high-purity nitrogen, high purity argon, high purity helium, high-purity hydrogen, high purity air as the working gas and other equipment for the carrier gas analysis instrument directly affect the stability of the test results and instrument. 3. The medical profession or medical laboratories, to provide patients with the use of oxygen breathing regulator, the use of nitrous oxide anesthesia, using a vacuum to attract waste, etc ... 4. Pharmaceutical laboratory nitrogen or argon purge residual hazardous substances. 5. Analysis of pesticide residues and veterinary concentrated pre-treatment process also requires a large amount of an inert gas, have a greater impact on the Trace Analysis and other analysis will be. If the gas supply does not meet the requirements, often causes abnormal instrument conditions, and even cause damage to the equipment, the medical profession would harm the patient's health. Therefore, the analysis system reliability, stability and accuracy of the instruments themselves and not only closely related, but also depends on external factors gases. Perfect laboratory gas distribution system is also an important indicator of the outstanding laboratory. Of laboratory gas supply is the basis of laboratory equipment to work, but also the security needs daily inspection work.
