Kev Tiv Thaiv Kab Mob thiab Tswj Lub Chaw kuaj cov cuab yeej sau npe 1 Gas Chromatograph: Qualitative and Quantitative Analysis 2 Abbe refractometer: ntsuas qhov refractive index thiab nruab nrab dispersion ntawm pob tshab translucent kua lossis khoom 3 ammonia analyzer: ntsuas cov ntsiab lus ntawm ammonia hauv cov qauv 4 Mercury analyzer: ntsuas mercury cov ntsiab lus hauv cov khoom thiab lub cev ua kua 5

Kev tu thiab kho cov khoom siv tshuaj lom neeg Lub chaw ua haujlwm ntawm cov khoom siv tshuaj lom neeg feem ntau hnyav, tsis muaj qhov kub thiab txias, lub tshuab nqus tsev lossis lub siab tsis tshua muaj siab, uas ua rau corrosion, hlawv thiab tawg. Tus nqi ntawm cov khoom siv tshuaj lom neeg nws tus kheej kuj tseem kim, thiab nws yog lub luag haujlwm nyuaj ntawm kev tsim khoom. Thaum ib qho tsis ua tiav,

Reactor kev khiav hauj lwm cov txheej txheem Ua ntej. Kev tshuaj xyuas thiab kev npaj ua ntej pib ua haujlwm 1. Lub cev ntawm cov tshuaj tiv thaiv lub lauj kaub yog huv si thiab huv si, thiab cov khoom siv tau ua tiav. Cov ntsuas ntsuas, lub tshuab nqus tsev, ntsuas qhov ntsuas kub, kev nyab xeeb li qub, li qub, thiab cov twj tso kua mis ntawm lub lauj kaub yuav tsum tau rhiab thiab raug. thiab muaj cov cim calibration tsis tu ncua.Kev tiv thaiv kev nyab xeeb, qhov cua, tawg-pov thawj thiab lwm yam khoom siv yog

lab iav siv (1) Cov raj siv tau siv ntau: me me ntawm cov tshuaj tiv thaiv cov hlab ntsha; Nws kuj tseem siv tau los ua lub thawv ntim khoom me me; los yog lub tshuab hluav taws xob rau kev txhim kho cov roj me me. (2) Beakers feem ntau yog siv rau: kom yaj cov khoom, cov tshuaj npaj thiab dilution thiab

Atomic fluorescence tov configuration Qhov kev npaj ntawm atomic fluorescence standard tov yog ib tug dilution txheej txheem, thiab cov high-concentration standard tov yuav tsum tau diluted mus rau qhov yuav tsum tau concentration raws li xav tau, thiab ua ib tug concentration sequence, thiab ntsuas atomic fluorescence tus nqi yog linearly. txiav txim siab. Yog li ntawd, kev npaj cov tshuaj yuav cuam tshuam ncaj qha

Cov cwj pwm tsis zoo nyob rau hauv lub lab Cov cwj pwm kev sim zoo tuaj yeem pab tus neeg sim ua kom tiav qhov kev sim ua tiav, thiab tus cwj pwm phem yuav ua rau koj qhov kev sim ua kom puas. Cov cwj pwm tsis zoo thaum lub sij hawm sim 1. Thaum tus qauv raug ntsuas los yog ntsuas, cov ntaub ntawv raug kaw thawj zaug rau ntawm daim ntawv, thiab cov qauv ua tiav thiab tom qab ntawd

10 lub sijhawm siv lub burette 1. Yuav ua li cas yog txoj kev ntawm oiling ib tug acid burette? A: Tshem tawm lub piston, siv daim ntawv huv los yog daim ntaub kom qhuav cov phab ntsa sab hauv ntawm lub piston thiab lub tes tsho. Siv tus ntiv tes txhawm rau me me ntawm Vaseline siv lub voj voog nyias ntawm ob qho kawg

Yuav ua li cas tshem tawm qhov kev ua yuam kev hauv qhov kev sim?Systematic yuam kev yog qhov sib txawv ntawm qhov nruab nrab ntawm cov txiaj ntsig ntawm qhov ntsuas tsis kawg ntawm qhov ntsuas tib yam thiab qhov tseeb tus nqi ntsuas nyob rau hauv cov xwm txheej rov ua dua. Nws feem ntau tshwm sim los ntawm yam tsis muaj kev zam. Ua rau systematic yuam kev Lub systematic yuam kev yog tshwm sim los ntawm

Yuav ua li cas xyuas cov cuab yeej hauv chav kuaj? Nyob rau hauv xyoo tas los no, nrog kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, kev nce qib ntawm kev sim thiab kev sim ua haujlwm, kev yuav khoom thiab kev yuav khoom ntawm cov cuab yeej kuaj thiab cov khoom siv tau hloov pauv ntau, thiab kev lees txais cov cuab yeej thiab cov cuab yeej siv tau dhau los ua txoj haujlwm tseem ceeb. ua tsis tau
