Ametryn

Cov txheej txheem no feem ntau yog siv rau cov ntsiab lus tshuaj tua kab, kev tshawb nrhiav qhov seem, kev tswj xyuas cov txheej txheem kom paub tseeb, ntsuas cov cuab yeej tshuaj ntsuam xyuas, thiab kev pom zoo thiab kev ntsuam xyuas cov txheej txheem tshuaj ntsuam xyuas hauv thaj chaw xws li zaub mov kev nyab xeeb, ib puag ncig, thiab kev ua liaj ua teb.

Cov neeg sib tw ntawm cov tshuaj no tus qauv (Atrazine, molecular mis: C9H17N5S, CAS naj npawb: 834-12-8) yog npaj los ntawm customizing tus coj cov tshuaj dawb huv cov khoom thiab ntxiv purifying nws los ntawm extraction, recrystallization, kem chromatography thiab lwm txoj kev raws li nws lub cev thiab tshuaj muaj zog. Tom qab kev soj ntsuam zoo thiab ua ntej, nws ua tau raws li qhov yuav tsum tau ua thiab qhuav thiab ntim.

Qhov tsis paub meej ntawm tus qauv tus nqi ua tiav txiav txim siab txog qhov tsis paub tseeb ntawm cov ntsiab lus ntawm kev txiav txim siab purity tseem ceeb, nrog rau cov dej noo, inorganic impurities, uniformity, stability, thiab lwm yam.

Daim ntawv thov

Raws li JJF1343-2012 "Cov Ntsiab Cai thiab Cov Ntsiab Cai ntawm Cov Cai rau Calibration of Reference Materials", random xaiv cov qauv ntim thiab siv cov roj chromatography (FID detector) los ua qhov kev ntsuas sib xws thiab kev ruaj ntseg ntawm purity. Cov txiaj ntsig kev xeem qhia pom tias muaj kev sib luag zoo thiab ruaj khov.

Qhov tsawg kawg nkaus sampling tus nqi rau cov qauv no yog 2mg. Cov yam ntxwv muaj nuj nqis thiab lawv qhov tsis paub tseeb ntawm cov khoom siv tau tsuas yog siv tau yog tias qhov ntsuas tsawg kawg nkaus tau ua raws. Cov txheej txheem no muaj lub sijhawm siv tau ntawm 5 xyoos txij li hnub ua haujlwm calibration. Lub chaw tshawb fawb thiab kev tsim kho yuav txuas ntxiv saib xyuas kev ruaj ntseg ntawm cov khoom siv no. Yog tias muaj kev hloov pauv ntawm tus nqi kom muaj nuj nqis thaum lub sijhawm siv tau, tus neeg siv yuav raug ceeb toom raws sijhawm.

Pob

Cov txheej txheem no tau ntim rau hauv cov xim av lub qhov ncauj iav fwj, nrog rau txhua lub raj mis tsis pub tsawg dua 100 mg.

Cia

Khaws rau hauv tub yees, tsaus, thiab qhuav.

Kev siv

Ua ntej siv cov qauv, nws yuav tsum sib npaug rau chav tsev kub. Tom qab qhib, lub foob yuav tsum tau rov qab los sai li sai tau thiab khaws cia raws li qhov xwm txheej.

Nco tseg

Cov txheej txheem no belongs rau cov tshuaj lom thiab teeb meem. Thaum siv nws, yuav tsum tau ceev faj kom tsis txhob nqus los yog sib cuag ntawm daim tawv nqaij.
