Tshuaj lom neeg cov pa dej (COD) Kev Ntsuas Cov Hlab yog cov cuab yeej tseem ceeb rau kev tsom xam lub nroog zoo, kev lag luam dav hauv ib puag ncig. Cov leeg tshwj xeeb yog tsim los kom cov neeg tiv thaiv kom kub thiab muaj mob hnyav thaum lub sij hawm cod ntawm lub plab zom mov. Cia peb ntsaub mus rau hauv cov yam ntxwv tseem ceeb thiab kev coj ua zoo tshaj plaws rau kev siv cov leeg ntsuas codes.

Hauv cov kws tshuaj ntsuam xyuas chaw soj ntsuam, cov kua txiv neej ua haujlwm yog qhov tseem ceeb rau kev ua kom ncaj qha los ntawm kev tshem tawm cov particulates ua ntej tsom xam. Txawm li cas los xij, lim cov kev lim dej-qhov uas teev dhau los ntawm lub lim-tuaj yeem hais haum cov cuab yeej. Nov yog cov tswv yim tseem ceeb los tiv thaiv cov teeb meem no:

1️⃣ polytetrafluoroethylene (ptfe) / / kev ua tau zoo: PTFE Cov Tshuaj Tiv Thaiv Kev Ruaj Ntseg

Tshuaj lom neeg cov pa kev thov (COD) kev xeem yog ib txoj kev tseem ceeb rau kev tshuaj xyuas cov dej zoo, tshwj xeeb hauv kev kho kom zoo thiab saib xyuas ib puag ncig. COD TUAM ROJ YEEB YOOJ YOOJ YIM Cov txheej txheem, tab sis kev siv yog qhov tseem ceeb rau tau txais cov txiaj ntsig raug

GC (roj chromatography) thiab GC-MS (roj d chromatography-huab cua tau siv los cais thiab txheeb xyuas cov chaw sib txuas.

Lub 11 hli Crimp Sab saum toj Autosampler vial 2ml yog lub iav vial zoo, 2 hli Crimp top, ntshiab iav vial. Cov hwj no tau sib haum nrog cov hom carsampers thiab haum rau siv nrog HPLC thiab GC Autosampers.

ToC vials yog pre-huv cov thawv ntim ua los ntawm cov iav zoo borosilicate iav lossis lwm cov khoom siv inert. Lawv tshwj xeeb yog tsim kom muaj kev phom sij me me uas cuam tshuam nrog cov kev pheej hmoo, kom muaj cov organic impurities tsis sket cov organic impurities tsis skeet cov organic impurities tsis sken cov toc nyeem.
