AS-60PlusHJ1261-2022 Benzene series automatic sampler

Fast and stable new generationHJ1261-2022 Benzene series automatic sampler

Purpose:Mainly used inVOCTheSVOCInject various gas samples such as non methane total hydrocarbons, gas bags, syringes, and soda tanks.

Applicable standards:J1261—2022Fixed pollution source exhaust gas Determination of benzene derivatives-Air bag sampling - direct injection - gas chromatography methodTheHJ38-2017Determination of fixed pollution source exhaust gas, total hydrocarbons, methane, and non methane total hydrocarbons-Gas chromatographyHJ 1006-2018 Determination of volatile halogenated hydrocarbons in fixed source exhaust gases Gas bag sampling Gas chromatography methodWait.

Features:

lMFC electronic mass flowmeter: precise control of sample flow rate, ensuring accuracy of standard and sample flow rates.

lFully Inert Pipeline System：No adsorption or residue, ensuring precise linearity and repeatability

lAutomatic standard curve: One click dilution of standard curve, fast and accurate.

lAutomatic sample dilution injection：One click dilution of high concentration samples.

lFully automatic sequential injection：Fast and stable.

lInjection method：standard configuration1mlQuantitative ring（0.5mlThe1mlThe2ml(Optional)

lSecondary sample dilution function: For high concentration samples, multiple gradient dilutions can be performed, and the dilution factor can easily exceed 10000 times. Sample injection number:16、32、48、64bit

lHeating function of transmission line, valve and quantitative ring: ensuring the sample transmission processChineseThere are no cold spots throughout the entire process.

lCeramic sample valve: no adsorption, no residue

lAutomatic sample pipeline cleaning function: After injection is completed, the sample pipeline can be automatically cleaned.

lBackblowing and pre blowing function: Before injection, nitrogen can be used to back blow the injection pipeline and pre rinse the sample pipeline with the sample.

lSample balancing function: Ensure pressure balance between the sample and the ambient atmosphere during the injection process to ensure injection accuracy.
