Detection and analysis of pyridine in air and exhaust gas
Detection and analysis of pyridine in air and exhaust gas Details:

Name: Capillary Column
Fixing fluid: cross-linked polyethylene glycol
Specification: 30 m?0.25 mm, 0.5 ?m film thickness
Model: PEG-20M
Application: "Ambient Air and Waste Gas Determination of Pyridine Gas Chromatography"

With the development of society and the continuous improvement of people's living standards, people have higher and higher requirements for the living and production environment, and their air quality has received more and more attention. As one of the more abundant air and exhaust gases, pyridine is very easy to cause people's physical discomfort and even threaten their health. Therefore, it is very important to do a good job in the detection of pyridine in the air and exhaust gas, and it is also the main method researched by the relevant staff.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. mainly studied the use of 5% ethanol aqueous solution as the main absorption liquid, directly implanted 1uL, and then analyzed by gas chromatograph, and detected and analyzed the air and waste with a hydrogen flame detector. The content of pyridine in. According to experiments, the content of pyridine is 0.01 mg/L, the absorption rate is 98%, the standard deviation rate is 8%, and the relevant standard value for curve sampling is Y=0.9993. According to relevant standards, these values can meet the expected standards and therefore meet the requirements for convenient, accurate and rapid detection of the substance.
