Cov Txheej Txheem Rau Kev Tshawb Nrhiav Propionic Acid
Propionic Acid Gas Chromatography (GC)
Qhov no yog ib txoj kev siv ntau thiab zoo rau kev nrhiav cov propionic acid. Ua ntej, xyuas kom meej tias cov roj chromatograph tau calibrated kom raug nrog cov parameters raug. Siv ib kem tsim nyog, xws li ib kem capillary, uas muab kev sib cais zoo rau propionic acid. Piv txwv li, piv txwv li kev tshuaj xyuas ntawm propionic acid hauv cov khoom noj, cov qauv khoom noj uas tau kho ua ntej raug txhaj rau hauv qhov nkag ntawm cov roj chromatograph. Cov qauv raug vaporized hauv qhov chaw txhaj tshuaj thiab nqa los ntawm cov roj nqa khoom uas muaj purity siab (feem ntau yog nitrogen) mus rau hauv kem. Cov roj nqa khoom uas muaj purity siab yog qhov tseem ceeb rau kev nrhiav kom raug. Hauv kem, propionic acid raug cais tawm ntawm lwm yam impurities raws li qhov sib txawv ntawm lawv cov coefficients faib ntawm cov theem ruaj khov thiab cov theem txawb. Cov tshuaj sib txawv tawm ntawm kem ntawm lub sijhawm sib txawv thiab mus txog lub tshuab ntes. Ib qho tshuab ntes uas siv ntau yog lub tshuab ntes nplaim taws ionization (FID), uas rhiab heev rau cov organic compounds uas muaj carbon. Thaum propionic acid mus txog lub tshuab ntes, nws tsim cov teeb liab hluav taws xob sib npaug rau nws qhov concentration. Los ntawm kev sib piv cov chromatogram uas tau los nrog qhov ntawm qhov paub tias muaj cov qauv propionic acid uas tau soj ntsuam nyob rau hauv cov xwm txheej zoo sib xws, cov ntsiab lus ntawm propionic acid hauv cov qauv tuaj yeem suav tau raws li thaj chaw ncov lossis qhov siab ncov.

Shandong Pulisi Chemical Co., Ltd. yog ib lub tuam txhab tsim khoom thiab muab cov kua qaub propionic zoo, muab cov qib sib xws rau cov khoom noj, tshuaj, kev lag luam thiab kev ua liaj ua teb. Peb cov kua qaub propionic yog tsim tawm raws li cov qauv tswj hwm zoo, ua kom muaj kev ntshiab siab, kev ua haujlwm ruaj khov thiab kev muab khoom zoo rau cov neeg siv khoom thoob ntiaj teb. Siv dav ua cov tshuaj preservative, pH regulator, thiab cov tshuaj nruab nrab, peb cov kua qaub propionic ua tau raws li cov lus qhia thoob ntiaj teb thiab txhawb nqa ntau yam kev siv los ntawm kev khaws cia zaub mov mus rau kev tsim cov organic. Peb muab cov ntim khoom yooj ywm, tus nqi sib tw, thiab kev txhawb nqa kev txawj ntse los ua kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom.info@pulisichem.cn
