Vim li cas kuv thiaj li yuav tsum ntsuas lub ntsuas hluav taws xob digital refractometer
Ua ntej ntsuas, ntsuas yuav tsum tau calibrated. Calibration tuaj yeem ua tau los ntawm kev siv dej distilled lossis cov iav txheem txheem (cov qauv iav yog cim nrog qhov ntsuas qhov ntsuas)
1. Calibrate nrog dej distilled
(1) Looen lub xauv xauv ntawm lub prism thiab so kom huv si (ceeb toom: siv cov dej phwj tuaj lossis lwm cov kuab tshuaj tsis haum, thiab so kom qhuav nrog daim ntawv lo ntsiab muag)
(2) Siv lub raj xa dej kom poob 2-3 tee dej distilled rau hauv nruab nrab ntawm ob lub prisms, kaw thiab kaw kom nruj
(3) Kho lub prism kom tig lub log kom lub refractive index nyeem raws nraim cov ntaub ntawv xav tau
(4) Tshawb xyuas seb cov kab sib faib dub thiab dawb ntawm lub raj hauv lub raj ntsuas lub lens puas sib haum nrog qhov kev sib tshuam ntawm lub diav rawg hlau. Yog tias nws tsis coincide, kho qhov ntsuas qhov ntsuas kom paub meej tias qhov kev sib tshuam ntawm lub diav rawg hlau yog sib npaug nrog cov kab sib faib; Yog hais tias qhov chaw saib yog me me hma liab dispersion, kho lub Amici prism handwheel kom txog thaum lub dispersion ploj.
2. Calibration nrog standard iav blocks
(1) Loosen lub prism locking ciaj ntswj thiab rub lub prism tuaj sib nrug
(2) Tso naphthalene bromide (siab refractive index kua) mus rau hauv qab polished nto ntawm iav thaiv thiab lo rau saum npoo ntawm shading prism. Lub polished ntsuas nto ntawm lub iav thaiv yuav tsum tig mus rau sab saud kom tau txais lub teeb thiab ua rau thaj chaw pom ntawm qhov ntsuas lub lens raj ci.
(3) Kho lub handwheel kom lub refractive index nyeem raws nraim qhov paub refractive index tus nqi ntawm tus qauv iav thaiv
(4) Yog tias txoj kab sib faib tsis sib haum nrog qhov kev sib tshuam ntawm rab rawg hlau thaum pom los ntawm kev ntsuas lub lens raj, kho cov ntsia hlau kom lawv sib npaug. Yog hais tias muaj dispersion, kho lub handwheel kom tshem tawm dispersion.
Kev tu thiab tu ntawm refractometer
Ua ntej thiab tom qab siv, thiab thaum hloov cov qauv, qhov chaw ua hauj lwm ntawm lub refractive prism system yuav tsum tau ntxuav ua ntej.
2. Cov cuab yeej yuav tsum tau muab tso rau hauv tsev nyob rau hauv qhov chaw qhuav thiab qhov cua zoo kom tsis txhob muaj pwm los ntawm kev tsim cov khoom siv kho qhov muag vim tias ya raws.
3. Thaum kuaj cov kua corrosive, kev ua haujlwm tu raws sijhawm (xws li cov khoom siv kho qhov muag, cov khoom hlau, thiab lawv qhov chaw) yuav tsum tau ua kom tsis txhob muaj kev puas tsuaj. Kev ntxuav tu yuav tsum tau ua tom qab siv lub cuab yeej
4. Cov qauv kuaj yuav tsum tsis txhob muaj cov impurities nyuaj. Thaum kuaj cov qauv khoom, qhov saum npoo ntawm lub refractive prism yuav tsum tau roughened los yog indented
5. Nco ntsoov khaws lub twj tso kua mis kom huv si, thiab nruj me ntsis kov cov khoom siv kho qhov muag nrog koj sab tes xis lossis hws. Yog tias muaj plua plav rau saum npoo ntawm qhov chaw kho qhov muag, koj tuaj yeem siv cov khoom siv qib high-qib deerskin lossis ntev fiber ntau paj rwb ntaub los maj mam so nws thiab qhuav nrog lub tshuab ziab plaub hau. Yog tias cov roj stains tshwm rau ntawm qhov chaw ntawm cov khoom siv kho qhov muag, lawv yuav tsum tau muab ntxuav tam sim nrog kev sib xyaw ntawm cawv thiab ether.
6. Cov cuab yeej yuav tsum zam kom tsis txhob muaj kev vibrations lossis cuam tshuam los tiv thaiv kev puas tsuaj rau cov khoom siv kho qhov muag thiab ntsuas qhov tseeb
7. Yog hais tias lub teeb nyob rau hauv lub tsom teeb pom kev zoo yog puas, lub tsom teeb yuav raug tshem tawm raws li axis, hloov nrog ib tug tshiab qhov muag teev, thiab sab laug thiab txoj cai txoj hauj lwm ntawm lub teeb yuav raug kho (looen cov nyob ib sab set screws) ua rau lub Lub teeb tsom rau ntawm qhov qis qis ntawm qhov refracting prism yam tsis ua rau muaj qhov sib txawv loj
8. Thaum lub condenser txawv, qhov ntsuas yuav tsum tau npog nrog lub hau yas los yog muab tso rau hauv lub thawv
9. Cov neeg siv tsis raug tso cai rau disassemble thiab sib sau ua ke Abbe refractometer condenser ntawm lub siab nyiam. Yog hais tias lub condenser malfunctions los yog ua tsis tau raws li qhov yuav tsum tau, nws yuav tsum tau tam sim ntawd xa mus kho.
