Dab tsi yog lub luag haujlwm ntawm HeadSpace vial ntawm GCMS tsom xam nyob rau hauv cov khoom xyaw ua hauj lwm?

Lub Kaum Hlis 6, 2019

20ml headspace vialsyog siv feem ntau ntawm GC thiab MS Kev Ntsuam Xyuas.

NDMA thiab NDEA yog qhov yooj yim tshaj plaws dialkylnitrosamines. Cov tebchaw no tau faib ua pawg 2a carcinogen (cov neeg muaj peev xwm) los ntawm lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv.

Tsis ntev los no, qee cov khoom siv tshuaj tau pom tias tau muaj paug nrog NDMA thiab NDEA. Nws ntseeg tau tias lawv tau qhia rau hauv cov khoom tiav thaum lub sijhawm ua tiav.

Nws yog qhov tseem ceeb kom muaj kev nkag siab, muaj tseeb, txhim khu kev qha thiab muaj zog ntsuas cov txheej txheem muaj raws cov txheej txheem uas tsim nyog. Ibheadspace roj chromatographyPawg Spectrometry txoj kev tau tsim los kuaj pom muaj NDMA hauv tshuaj yeeb tshuaj.

Hauv qhov kev sim no, HeadSpace-autosampler hs-20 lub cuab yeej siv yuav raug siv. Kom haum rau cov twj paj nruag headspace no,20mm crossp headspace vialyuav tsum raug xaiv. Nyob rau hauv Aijiren cov khoom lag luam catalog, muaj 6mL, 10ml, 20ml vials, uas nws qhov loj me ntawm 20mm crimp vial.

Kev sib xyaw ntawm NDMA thiab NDEA tau siv los npaj cov tshuaj calibration sib luag los ntawm 2.5-10 di ug \ / l. Raws li reagent ntim, 10ml headspace crimp vial yog lub ce ib.

Aijiren yog ib qho ntawm cov chromatography loj tshaj plaws hauv chromatograble muaj nyob rau sab qab teb ntawm Suav teb. NwsHeadspace Crimp Vialmuaj ntau tus qauv. Tab sis txhua lub headspace crimp vial yog cov nqi lag luam wholesale. Thov nug peb rau cov qauv dawb txog crimp headspace vial.

Hauv koj qhov txuas ntxiv GCMS sim txog cov khoom xyaw ua tshuaj, lub taub hau vial yog lub luag haujlwm tseem ceeb.
