Hais Meter Acidity Meter thiab cov txheej txheem cia
Thaum ntsib cov xwm txheej uas HT Meter cov meter elidity tau siv rau ib lub sijhawm thiab cov kab nqes txo qis, cov hauv qab no tuaj yeem sim, raws li hauv qab no:
Yog tias cov qauv ntsuas yog cov oily / organic, nws tuaj yeem ntxuav nrog acetone lossis hexanol.
2. Qhib lub electrode membrane.
3. Yog tias cov ntsuas ntsuas thiab acidity anidier ntsuas muaj cov protein nyob rau hauv cov qauv, pob hluav taws xob ua kom huv si / hydrochloric acid ntxuav tov (MOV13440068).
4. Yog tias electrode kua network ntawm acidity Meter yog qias neeg thiab dub, thiol tu daws (ME51340) tuaj yeem siv los ntxuav cov kua network.
Kev cia cov txheej txheem rau cov nkauj anidity electrode:
Thov khaws cov electrode nyob rau hauv ib tug 3mol / l poov tshuaj tshuaj tov (3mkcl) thaum tsis siv; Nws tuaj yeem khaws cia rau hauv pH 7. 00 tsis daws tau rau lub sijhawm luv luv. Ziab lossis so kom cov kua txob acidity elos eloster elidilled hauv dej distilled rau lub sijhawm ntev yuav ua rau lub neej pabcuam ntawm electrode.
Thaum lub composite electrode tsis yog siv, nws tuaj yeem sib xyaw ua ke hauv 3m poov tshuaj tshuaj chloride tov. Tsis txhob xau dej hauv xab npum lossis lwm yam nqus dej uas nqus tau.
Ua ntej siv, tshawb xyuas cov npuas ntawm cov iav pem hauv ntej kawg ntawm lub iav electrode. Nyob rau hauv ib txwm muaj xwm txheej, lub electrode yuav tsum tau pob tshab thiab dawb ntawm cov kab nrib pleb; Cov npuas yuav tsum tau sau nrog kev daws thiab yuav tsum tsis muaj npuas tsis muaj.
Thaum ntsuas cov kev daws teeb meem siab, sim ua kom lub sijhawm ntsuas kom luv npaum li ntau tau, thiab tiv thaiv cov kua ntsuas los ntawm electrode thiab paug nws.
Tom qab tu electrode, tsis txhob siv cov ntawv lim los so cov ntawv zaj duab xis, tab sis tiv thaiv kev ua yeeb yaj kiab iav kom qhuav, thiab cuam tshuam rau kev ntsuas qhov tseeb.
Thaum ntsuas kev ntsuas, ua tib zoo saib xyuas kom tshem tawm cov chaw siv hluav taws xob hauv lub teeb kom tsis txhob muaj qhov tshwm sim hauv cov zaub sib tw hauv cov khoom ntawm lub ntsuas. Thaum siv, ceev faj maj mam maj mam co chav electrode ob peb zaug.
Lub ntsiab lus ntsuas hluav taws xob tsis tuaj yeem siv rau cov kua qaub muaj zog, hauv paus muaj zog, lossis lwm yam kev daws teeb meem. Nws yog nruj me ntsis txwv tsis pub siv nyob rau hauv lub cev qhuav me me xws li anhydrous hexanol, poov tshuaj Dichromate, thiab lwm yam.
