Non-methane hydrocarbon analyzer non-methane hydrocarbon detector model: RP-GS-101FÎ
Principle The content of total hydrocarbons and methane hydrocarbons in the air was determined by a gas chromatograph using a flame ionization detector. The difference between the two is the content of non-methane hydrocarbons. When the total hydrocarbon is determined by using nitrogen as a carrier gas, the peak of the total hydrocarbon includes an oxygen peak, and the oxygen in the gas sample causes positive interference. Under fixed chromatographic conditions, the response of a certain amount of oxygen is fixed, so the blank value can be obtained by purifying the air and subtracted from the total hydrocarbon peak to eliminate oxygen interference. Overview: Non-methane hydrocarbon gas chromatographs are developed in strict accordance with the "national standards for the removal of hydrocarbon purifiers." It features high sensitivity, high accuracy, high resolution, high analysis speed, and simple analysis methods. Therefore, it has been widely used in petroleum, chemical, metallurgy, food, environmental protection, medicine, commodity inspection, national defense, teaching and scientific research departments. Its application is of great significance for improving product quality and production technology. Features: â—† Microcomputer temperature controller, PID adjustment, three-way temperature control, over-temperature protection; â—† FID uses dedicated micro-current amplifier, high sensitivity, long service life;; â—† Any one temperature over-limit will alarm and automatically power off protection. Technical indicators: 1. Boot stability time:
