Khoom Description
pH daim ntawv xeem yog siv los ntsuas cov acidity thiab alkalinity ntawm cov tshuaj. Qhov no yog ib daim ntawv xeem npaj txhij. Thaum siv nws, rhuav tshem ib daim kab xev thiab muab tso rau hauv lub iav saib. Siv ib lub khob iav qhuav kom poob ib qho kev daws teeb meem los kuaj, lossis siv cov roj hmab dropper los nqus nws. Muab cov tshuaj tso rau hauv nruab nrab ntawm daim ntawv xeem, thiab tom qab ntawd sib piv cov xim hloov ntawm daim ntawv xeem nrog cov qauv xim kom paub cov acidity thiab alkalinity ntawm cov tshuaj, uas yog yooj yim heev.
PH Test paper Instruction
:
1. Ntsuam xyuas cov acidity thiab alkalinity ntawm cov tshuaj: rhuav tshem ib daim ntawm pH kuaj daim ntawv, siv ib tug roj hmab-tipped burette kom poob rau hauv cov tshuaj, hloov cov xim rau ib nrab ib tug thib ob thiab sib piv cov xim nrog daim card xim ntawm lub pob. ; los yog noj cov tshuaj me me, ntub cov kua dej ncaj qha nrog cov ntawv xeem, thiab tom qab ntawd sib piv cov xim rau ib nrab thib ob raws li daim npav xim ntawm lub pob.
Kev sib piv nrog daim npav colorimetric; koj tseem tuaj yeem nqa ib daim ntawv xeem me me rau ntawm daim iav saib lossis ib daim iav, siv lub iav huv thiab qhuav qhuav dipped rau hauv cov kua los kuaj poob rau hauv nruab nrab ntawm daim ntawv xeem, soj ntsuam cov xim hloov yog ruaj khov, thiab tom qab ntawd muab piv nrog tus qauv colorimetric card los txiav txim qhov xwm txheej ntawm cov tshuaj.
2. Ntsuas cov kua qaub thiab alkalinity ntawm cov roj: ua ntej moisten daim ntawv xeem nrog dej distilled, lo daim ntawv xeem ntawm ib kawg ntawm lub iav pas nrig, thiab tom qab ntawd xa daim ntawv xeem mus rau lub qhov ncauj ntawm lub thawv uas muaj cov roj mus kuaj. . Saib xyuas cov xim hloov los txiav txim qhov xwm ntawm cov pa.

Cov ntsiab lus ntawm pH Test strips:
Cov kev ceev faj:
1. Daim ntawv kuaj pH tsis tuaj yeem muab tso ncaj qha rau hauv cov tshuaj.
2. pH Daim Ntawv Xeem Strips tsis tuaj yeem ntsuas pH ntawm concentrated sulfuric acid.
3. Daim ntawv xeem yuav tsum tsis txhob kov lub qhov ncauj qhov ncauj, lub qhov ncauj lub raj mis, lub qhov ncauj catheter, thiab lwm yam.
4. Thaum ntsuas pH ntawm cov tshuaj, cov ntawv xeem yuav tsum tsis txhob ntub dej distilled ua ntej, vim qhov no yuav ua rau qhov ntsuas tsis raug. Txoj kev raug yog siv lub iav pas nrig dipped nyob rau hauv qhov kev daws teeb meem los kuaj thiab tso rau hauv nruab nrab ntawm daim ntawv xeem. Tom qab daim ntawv xeem hloov xim, muab piv nrog daim npav xim qauv los txiav txim siab pH ntawm cov tshuaj.
5. Tom qab tshem tawm cov ntawv xeem, lub thawv ntim cov ntawv xeem yuav tsum tau kaw kom nruj kom tsis txhob muaj cov pa phem los ntawm qee qhov chaw kuaj.
6. Nws yuav tsum tau siv nyob rau hauv chav tsev kub, txwv tsis pub cov txiaj ntsig yuav tsis raug.
