Malathion hauv Methanol

Cov txheej txheem no yog npaj kom raug siv txoj kev muaj peev xwm hnyav nrog methanol ua cov kuab tshuaj thiab Malathion cov khoom ntshiab (molecular mis: C10H19O6PS2, CAS rau npe: 121-75-5) raws li tus neeg sib tw raw khoom, nrog rau tus qauv purity tus nqi.

Code.	Khoom npe	Tus nqi tsim nyog (%)	Cov txheeb ze tsis paub tseeb (%), (k=2)
GBW(E) 061402	Standard tshuaj rau malathion tov nyob rau hauv methanol	1.00	4

 

Traceability thiab calibration txoj kev

 

Lub purity ntawm tus neeg sib tw raw cov ntaub ntawv rau tus qauv tshuaj no yog txiav txim siab siv roj chromatography (GC/FID) txoj kev tsom xam. Siv tus nqi npaj raws li tus qauv tus nqi ntawm cov qauv tshuaj, cov txheej txheem npaj cov khoom siv thiab cov qauv kev tswj xyuas zoo raug muab piv thiab suav nrog cov roj chromatography (GC / FID detector) los xyuas cov nqi npaj.

 

Los ntawm kev siv cov txheej txheem kev npaj, kev ntsuas, thiab ntsuas cov cuab yeej uas ua tau raws li qhov yuav tsum tau ua ntawm metrology, xyuas kom meej qhov traceability ntawm qhov muaj nuj nqis ntawm cov khoom txheem.

 

Daim ntawv thov

 

Xa mus rau JJF1343 National Metrology Technical Specification (sib npaug ISO Guide 35), random xaiv cov ntim cov qauv thiab siv roj chromatography (GC/FID detector) los ntsuam xyuas cov uniformity thiab stability ntawm cov tshuaj. Cov txiaj ntsig kev xeem qhia pom tias muaj kev sib luag zoo thiab ruaj khov.

 

Cov txheej txheem no muaj lub sijhawm siv tau ntawm 2 xyoos txij li hnub 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, Cia thiab Sau

 

• Pob

Cov txheej txheem no yog ntim rau hauv iav ampoules, nrog ntim ntawm 2mL ib vial. Ua kom raug tshem tawm raws li xav tau thaum siv.

• Cia

Khaws rau hauv tub yees thiab tsaus ntuj. Ua ntej siv, sib npaug ntawm chav tsev kub (20 ± 3 degree) thiab co sib npaug. Lub raj mis ampoule
Thaum qhib, nws yuav tsum tau siv tam sim ntawd thiab tsis tuaj yeem siv los ua cov ntaub ntawv siv tom qab tau yaj dua.

• 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.
