Sep 18, 2025
Taw qhia
Graphite rods ntawm spectral purity thiab siab -purity rotating disk electrodes (RDEs) yog cov ntaub ntawv tseem ceeb nyob rau hauv roj av tsom xam, spectroscopic xeem, thiab electrochemical daim ntaub ntawv. Cov khoom no muab lub hauv paus ruaj khov rau cov chaw soj ntsuam thiab cov kws tshawb fawb uas xav tau cov txiaj ntsig zoo, rov ua dua. Lub purity ntawm graphite ncaj qha cuam tshuam cov cim keeb kwm yav dhau, cuam tshuam theem, thiab cov chaw soj ntsuam kev ntseeg siab muaj nyob rau hauv lawv cov ntaub ntawv.
Thaum txoj kev tshawb pom txawv ntawm -xws liICP{0}}OES (Optical Emission Spectrometry)rauICP-MS (Mass Spectrometry), GD-MS (Glow Discharge Mass Spectrometry),thiabtshauv kuaj- qhov zoo ntawm cov khoom siv graphite tseem yog qhov tseem ceeb. SHJ CARBON tsom rau kev muab cov- impurity qis, batch- traceable graphite rods thiab disks, kom cov neeg siv khoom tuaj yeem xaiv txoj hauv kev sim uas zoo tshaj plaws rau lawv daim ntawv thov.
Kev Tshawb Fawb Kev Siv Feem ntau siv hauv kev lag luam
Laboratories siv ntau txoj hauv kev los ntsuas cov impurities hauv graphite. Txhua tus muaj nws lub luag haujlwm, nyob ntawm qib ntawm precision yuav tsum tau thiab cov khoom siv muaj. SHJ CARBON cov ntaub ntawv yog tsim los kom haum raws li txoj kev no.
1. ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry)
ICP-OES tseem yog ib txoj hauv kev rau ntau lub chaw kuaj mob thoob ntiaj teb. Nws ntsuas atomic emission kab tom qab kev daws teeb meem -raws li kev npaj ua qauv.
- Lub zog:Muaj dav dav, ua tau zoo rau nruab nrab - theem concentrations.
- Kev txwv:Tsawg dua qhov tseeb ntawm ultra- qib taug qab vim qhov txwv tsis pub kuaj pom thiab cov qauv kev zom zaub mov.
- Khoom siv:Txawm tias thaum siv ICP-OES, ultra- qis- cov hmoov tshauv graphite rods pab txo qis kev cuam tshuam hauv paus thiab txhim kho cov teeb liab sib xws.
2. ICP-MS (Inductively Coupled Plasma Mass Spectrometry)
ICP-MS muaj qhov rhiab heev dua piv rau ICP-OES, ua rau nws haum rau kev taug qab thiab ultra- taug qab impurity detection.
- Lub zog:Muaj peev xwm txheeb xyuas cov qib -ppm; dav txais nyob rau hauv semiconductor thiab cov ntaub ntawv industries.
- Kev txwv:Yuav tsum tau digestion, uas qhia txog tej yam kab mob.
- Khoom siv:Peb cov graphite rods thiab RDE disks, muab rau hauv cov ntim huv si, txo cov kab mob sab nraud thaum lub sij hawm zom zaub mov, txhawb ICP kom raug -MS cov txiaj ntsig.
3. GD-MS (Glow Discharge Mass Spectrometry)
GD-MS yog cov txheej txheem tshawb xyuas ncaj qha feem ntau siv rau siab - cov ntaub ntawv purity.
- Lub zog:Tshem tawm qhov xav tau rau kev zom zaub mov; ua tiav ppb-tsis tshua muaj ppm kuaj pom qhov txwv.
- Kev txwv:Yuav tsum muaj cov cuab yeej tshwj xeeb uas tsis muaj nyob hauv txhua qhov chaw sim.
- Khoom siv:Spectral-purity graphite rods thiab disks yog sib xws nrog GD-MS workflows, txo cov kauj ruam npaj thiab xyuas kom meej traceability.
4. Kev kuaj tshauv (Gravimetric Method)
Kev kuaj tshauv yog qhov yooj yim, tus nqi -hloov zoo- kuaj xyuas cov graphite zoo. Siv lub cub tawg, qhov sib npaug, thiab cov crucibles, cov chaw soj ntsuam tuaj yeem ntsuas tag nrho cov hmoov tshauv.
- Lub zog:Cov cuab yeej yooj yim, muab tag nrho impurity benchmark.
- Kev txwv:Tsis qhia tus kheej cov ntsiab lus.
- Khoom siv:Peb cov graphite rods ua kom pom cov hmoov tshauv zoo ib yam thoob plaws cov khoom siv, ua rau lawv muaj kev ntseeg siab rau gravimetric validation.
Vim li cas cov khoom xaiv tseem ceeb hauv kev sim?
Txoj kev kuaj pom tau xaiv los ntawm lub chaw kuaj mob cuam tshuam li cas cov txiaj ntsig tau txhais. Txawm li cas los xij,kev ntseeg tau ntawm cov txiaj ntsig tau pib nrog cov khoom siv graphite nws tus kheej.
Hauv qee cov neeg siv khoom qhia, qhov txawv txav tsis zoo tau raug kaw, xws li poob nthav siab niobium (Nb) concentrations. Cov kev tsis txaus ntseeg no tuaj yeem tshwm sim los ntawm cov qauv kev npaj ua paug, ntsuas -kev cuam tshuam tshwj xeeb, lossis cov qauv tsis sib xws.
Los ntawm kev xaivhuv si, batch-sib xws graphite rods, lub chaw soj nstuam txo qhov kev pheej hmoo ntawm kev nyeem ntawv cuav qhia thaum npaj. Peb cov txheej txheem ntim khoom thiab kev lees paub zoo yog tsim los txhawb cov chaw soj nstuam, tsis hloov lawv txoj hauv kev, muab cov kws tshuaj ntsuam xyuas kev ntseeg siab tias qhov tsis txaus ntseeg cuam tshuam txog cov qauv qauv tiag tiag es tsis yog lwm yam.
