Cov kev xav tau ua ntej ntawm cov qauv ntawm cov sim hluav taws xob rauv kub ashing txoj kev

1. Txawm hais tias tus qauv yuav tsum tau pretreated, yuav ua li cas pretreat nws, thiab yuav ua li cas cov qauv ntawm cov qauv yuav tsum tau coj mus rau hauv tus account yuav tsum tau raws li cov yam ntxwv ntawm cov qauv, qhov yuav tsum tau ntawm kev soj ntsuam, thiab cov kev ua tau zoo ntawm lub analytical instrument siv;

2. Pretreatment yuav tsum tau zam los yog siv tsawg li tsawg tau, thiaj li yuav txo tau cov kauj ruam ntawm kev ua hauj lwm, kom ceev cov kev soj ntsuam, thiab txo cov kev tsis zoo tshwm sim los ntawm cov txheej txheem pretreatment, xws li kev taw qhia ntawm cov pa phem thiab poob ntawm cov khoom rau raug kuaj;

3. Thaum cov qauv ua tiav los ntawm cov txheej txheem decomposition, cov decomposition yuav tsum ua kom tiav yam tsis ua rau poob ntawm cov khoom kuaj sim, thiab tus nqi rov qab ntawm cov khoom kuaj yuav tsum siab txaus;

4. Cov qauv tsis tuaj yeem raug paug, thiab cov khoom yuav tsum tau kuaj thiab cov khoom uas cuam tshuam rau kev txiav txim siab tsis tuaj yeem qhia tau;

5. Kev noj cov tshuaj reagents yuav tsum tsawg li sai tau, cov txheej txheem yog yooj yim thiab yooj yim, ceev, thiab tsis muaj kuab paug rau ib puag ncig thiab cov neeg ua haujlwm.
