Cov kev cai tsim nyog rau kev ntsuam xyuas hauv chav kuaj tshuaj chemical reagents yog cov tshuaj purity siab uas ua tau raws li qee qhov kev xav tau zoo thiab yog cov khoom siv rau kev ua haujlwm analytical. Lub purity ntawm cov reagent yog ib qho tseem ceeb heev rau kev ntsuam xyuas analytical. Nws yuav cuam tshuam qhov tseeb ntawm qhov tshwm sim. Yog hais tias lub purity ntawm lub reagent tsis tau raws li

Cov kauj ruam yooj yim hauv kev tshuaj xyuas zaub mov hauv chav kuaj Cov kauj ruam yooj yim ntawm kev tshuaj xyuas zaub mov yog: kev sau cov qauv; kev ua qauv; kev soj ntsuam kuaj thiab kuaj xyuas; tsom xam tau sau thiab ua nyob rau hauv plaub theem. 1 Kev sau cov qauv Kev sau cov qauv, tseem hu ua sampling thiab qauv npaj, yog hais txog kev rho tawm ntawm tus qauv sawv cev rau kev tshuaj xyuas

Cov yam tseem ceeb uas cuam tshuam rau qhov hnyav ntawm cov khoom siv hluav taws xob 1, lub sijhawm khaws cia Cov khoom siv hluav taws xob hluav taws xob yog lawv tus kheej cov cuab yeej hluav taws xob sophisticated. Thaum khaws cia ntev, lawv yuav ua rau muaj kev sib txawv hauv lawv cov tshuab hluav taws xob sab hauv, thiab tom qab ntawd cov txiaj ntsig ntawm symmetry yuav cuam tshuam rau lawv. Yog li ntawd, ua ntej siv hluav taws xob sib npaug rau qhov hnyav, nco ntsoov sib npaug

Kev ua kom huv huv thiab kev sib cais ntau hauv cov chaw soj nstuam Purification hais txog kev ua kom huv ntawm cov khoom sib xyaw kom tshem tawm cov impurities, thiab tau txais cov khoom siv hauv cov khoom sib xyaw, thiab cov purified impurities tsis tas yuav xav txog cov tshuaj muaj pes tsawg leeg thiab lub cev lub cev. Muaj ntau txoj hauv kev los cais cov sib tov, tab sis lawv tuaj yeem muab faib ua ob pawg dav
