Tsis siv neeg potentiometric titrator yog qhov ntsuas zoo tshaj plaws muaj peev xwm ntsuas tshuaj rau lub chaw soj nstuam tshuaj. Nws yog qhov tsim nyog rau kev tshuaj ntsuam ntawm cov khoom siv hauv ntau yam kev lag luam xws li kev tiv thaiv ib puag ncig tsev kawm ntawv tshuaj lom neeg, kev siv tshuaj thiab cov chaw muag tshuaj, rau cov kua qaub-puag lub cev, redox titration, thiab tsis-aqueous titration. Qhov ntsuas kuj yog 0.01-qib high-precision PH ntsuas, uas tuaj yeem siv tau ua ntsuas precision PH ntsuas hauv chav kuaj. Qhov ntsuas no muaj cov haujlwm xws li kev ua haujlwm tsis siv neeg, thiab lub ntim titration tus nqi muaj LED ncaj qha cov zaub tso tawm. Nws yog qhov yooj yim heev thiab intuitive txawm hais tias nws yog nqis tes los yog preset kawg point automatic titration.
Npaj ua ntej siv lub automatic potentiometric titrator:
1. Ua ntej pib pib, xyuas qhov ntsuas ua ntej. Tshawb xyuas seb qhov siv cov khoom siv li qub raug ntsuas tag nrho, seb puas muaj cov khoom siv yooj yim tau nruab rau hauv qhov chaw, thiab seb cov khoom sib txuas ntawm cov kav xa dej puas ntseeg tau. Kuaj seb qhov sib txuas sib txuas ntawm lub teeb hluav taws xob sib txig sib luag thiab raug.
Thaum siv cov nplaim hluav taws xob txuas rau kev kuaj, qhov hluav taws xob txuas ntawm cov nplaim hluav taws xob yuav tsum tau muab tso rau hauv cov electrode qhov (1); thaum siv cov ntsuas hluav taws xob ntsuas thiab qhov siv hluav taws xob siv hluav taws xob, lub Q9 luv luv txuas lub ntsaws yuav tsum tau muab tso rau hauv lub qhov (1), thiab lwm qhov ob electrodes yuav tsum txuas nrog ntsuas ntsuas qhov ntsuas electrode. (2) Lub Chaw Nres Tsheb (1) tau txuas nrog. (Nco tseg: rau ib qho kev xeem twg, lub tshuab hluav taws xob (1) yuav tsum tsis txhob nyob ib leeg).
2. Yog tias kev them nyiaj ib feem kaum (xws li nyiaj nitrate AgNO3) uas tuaj yeem tsim cov nag lossis dej cawv tau siv rau hauv kev ntsuas dhau los, lub burette yuav tsum ua tib zoo ntxuav kom tsis txhob muaj crystallization thiab kev puas tsuaj rau lub valve.
3. Tsis txhob hloov lub burette ua ntej pib. (Lub burette hauv kev siv ntawm lub ntsuas yuav tsum ua kom tiav qhov kev nqis rov qab, thiab lub piston tuaj yeem hloov tau tsuas yog thaum lub piston nyob ntawm qhov chaw tuag hauv qab txoj haujlwm).
4. Txheeb xyuas qhov ntim ntawm titrant, uas yuav tsum tsis pub tsawg tshaj 5ml. Yog tias" oxidation-txo titration" hom yog xaiv, qhov kev daws teeb meem rau hauv lub khob tov yuav tsum tsis pub tsawg tshaj 100ml.
5. Lub sijhawm sib nrug ntawm lub khau kawg thiab lub khau raj tam sim no yuav tsum tsis pub tsawg dua 1 feeb.
Ceev faj ua ntej siv lub tshuab raj potentiometric tsis siv neeg:
1. Lub davhlau ya nyob twg (qhov hluav taws xob qhov hluav taws xob) ntawm lub ntsuas yuav tsum ua kom qhuav thiab huv. Thaum qhov ntsuas tsis nyob hauv kev siv, ntxig Q9 ntu luv txuas lub ntsaws rau hauv lub qhov (socket) kom tiv thaiv kev nkag mus ntawm hmoov av thiab ya raws.
2. Thaum ntsuas ntsuas lub ntsuas nrog qhov tsis daws teeb meem, kom ntseeg tau tias qhov kev daws teeb meem tsis raug, thiab tsis txhob sib tov cov teeb meem tsis haum, txwv tsis pub ntsuas qhov ntsuas yuav tsis raug.
3. Thaum ntsuas, ntsuas cov hlau lead ntawm cov electrode yuav tsum khaws cia tseem tshuav, txwv tsis pub nws yuav ua rau ntsuas ntsuas tsis ruaj khov.
4. Kev siv sab nraud ntawm cov khoom siv hluav taws xob (lossis calomel electrode) yuav tsum mloog zoo rau cov tshuaj tua kab mob potassium chloride thiab cov khoom ntxiv tau ntxiv los ntawm lub qhov me me nyob rau sab saum toj ntawm cov electrode.
5. Tom qab tshem cov electrode npog, tsis txhob tiv tauj ntawm cov iav rhiab ntawm cov electrode nrog cov khoom tawv, vim tias ib qho kev puas tsuaj los yog khawb yuav ua rau cov electrode tsis tuaj.
6. Tsis txhob siv lub sijhawm ntev ntawm qhov electrode hauv cov dej distilled, protein tov thiab kua qaub fluoride tov.
7. Lub tshuab hluav taws xob yuav tsum tsis txhob tiv tauj nrog cov roj silicone.
8. Ua ntej ua ntej titration, yaug solenoid valve roj hmab raj dej ntau zaus nrog tee.
9. Tom qab mus txog qhov kawg, koj tsis tuaj yeem nias" Kev Tso Cai Pib" khawm, txwv tsis pub ntsuas yuav pib ua haujlwm titration dua.
10. Tsis txhob siv cov tshuaj potassium permanganate thiab lwm cov kev daws teeb meem uas ua haujlwm nrog rubber hoses.
