Common gas chromatograph instrument maintenance method

Abstract: the common gas chromatograph instrument maintenance methods of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas chromatograph is often used for quantitative analysis of the organic matter, when the instrument is running after a period of time, due to static electricity, instrument internal easy to absorb more dust; PCB and PCB socket except with dust adsorption, also often and some organic vapor adsorption. More flow meter manufacturers choose model price quote you are welcome to inquire, the following is a common gas chromatograph instrument maintenance methods of the article details. Gas chromatograph is often used for quantitative analysis of the organic matter, when the instrument is running after a period of time, due to static electricity, instrument internal easy to absorb more dust; PCB and PCB socket except with dust adsorption, often with some organic vapor adsorption; , because of lower part of the freezing point of the organic matter in the injection port position often find solidification of organic matter, distribution piping in use after a period of time, inner diameter and even blocked by organic matter; In use process, TCD detector are likely to be organic matter pollution; FID detector for a long time used in analysis of organic matter, organic matter in the nozzle or collect pole position deposit or nozzle, collect some carbon deposit often occurred. 1 instrument internal purging, clean ( Henan, hubei, hunan, agilent gas chromatograph/gas chromatography maintenance) Gas chromatograph after downtime, open the side and back panel of the instrument, instrument air or nitrogen purging of instrument internal dust to dust more or it is not easy to purge the place with a soft brush with handle. Purging is completed, the existence of the local water organic pollution of an instrument or organic solvent to scrub, to wipe water soluble organic matter to water, in areas not thoroughly clean can be treated with organic solvent, the water-insoluble or may react with water with organic matter does not react with the organic solvent to clean, such as toluene, acetone, carbon tetrachloride, etc. Note that in the process of wiping instrument can't surface of instrument or other components caused by corrosion or secondary pollution. 2 circuit board maintenance and cleaning, Henan, hubei, hunan, agilent gas chromatograph/gas chromatography maintenance) Gas chromatograph preparation before repair, cut off the instrument power, first with instrument air or nitrogen purging of circuit board and circuit board slot, purging with a soft brush with dust in the circuit boards and slot more carefully clean up the part. Try to wear gloves during operation, to prevent electrostatic or hand perspiration impact part of the circuit board components. Purging work is completed, the usage of circuit board should be carefully observed, whether printed circuit boards or electronic components have obvious corrosion phenomenon. For circuit boards with organic matter of electronic components and printed circuit with dip in with cotton wool take alcohol to wipe, PCB interface and slot part also want to wipe. 3 injection port cleaning ( Henan, hubei, hunan, agilent gas chromatograph/gas chromatography maintenance) In the maintenance, the gas chromatograph sample mouth glass liner, shunt tablet, injection port distribution piping, EPC etc. Parts are cleaning is very necessary. Glass liner and diversion plate cleaning: be careful to take out the glass liner from the instrument, use tweezers or other small tools carefully remove the liner of glass wool and other impurities, move the process not to scratch the surface of the liner. If the condition allows, can be preliminary cleaning glass liner in organic solvent by ultrasonic cleaning, drying after use. Can also clean directly with the organic solvents such as acetone, toluene, after completion of cleaning after drying can be used. Shunt tablet zui for ideal cleaning method is ultrasonic processing in solvent, drying after use. Also can choose a suitable organic solvent to clean: from the injection port shunt tablet, after first use the inert solvent cleaning, such as toluene with methanol alcohol solvent cleaning, drying after use. Bypass of the pipeline cleaning: gas chromatograph in analysis of organic and polymer compounds, many organic compounds with low freezing point, samples from the gasification chamber through the bypass pipeline in the process of organic matter in the shunt line set. Gas chromatograph after long time of use, the inner diameter of the pipe diversion became smaller, and even completely blocked. Distribution piping blocked, instrument, injection port display abnormal pressure peak deformation difference, abnormal results. In the process of maintenance, whether can advance judge distribution piping without blocking phenomenon, all need to bypass pipeline cleaning. Distribution piping cleaning generally choose the organic solvents such as acetone, toluene, distribution piping of jams sometimes used simple cleaning methods are difficult to clean, need to take some other auxiliary mechanical method to complete.
Many of us have heard about mass flow meter and seen some of these units in operation in insertion ultrasonic flow meter, fork density meter manufacturer and v shape coriolis mass flow meter spaces.
