Product Overview
High-Purity Nitrogen yog ib qho inert, tsis yog -reactive gas qhov tseem ceeb rau kev lag luam uas txawm tias cov kab tsis huv tuaj yeem cuam tshuam cov khoom ncaj ncees, cov txheej txheem kev ruaj ntseg, lossis kev txheeb xyuas qhov tseeb. Tau txais los ntawm kev sib cais ntawm huab cua thiab kev ua kom huv huv, cov pa roj no yog qhov tsis tshua muaj oxygen, noo noo, hydrocarbons, thiab lwm yam kab mob. Raws li qhov kawg tiv thaiv thiab purging nruab nrab, siab purity nitrogen yog indispensable rau tiv thaiv oxidation, paug, thiab pliaj tshuaj tiv thaiv nyob rau hauv ib puag ncig rhiab heev. Kev ntseeg siab ntawm High-Purity Nitrogen yog lub hauv paus rau kev tsim khoom zoo tshaj plaws hauv cov khoom siv hluav taws xob, tshuaj, thiab cov khoom siv qib siab.

Muab ib puag ncig zoo tsis muaj oxygen thiab noo noo, tseem ceeb heev rau kev tiv thaiv cov ntaub ntawv rhiab ntawm oxidation, hydrolysis, thiab degradation.
Superior Contamination Control
Tsawg heev ntawm cov hydrocarbons thiab cov khoom tiv thaiv kev sib kis ntawm qhov chaw, cov yeeb yaj kiab tsis xws luag, thiab catalyst lom nyob rau hauv high -tech manufacturing.
Cov txheej txheem ua tau zoo
Guaranteed purity ua kom rov ua tau zoo dua hauv cov txheej txheem tseem ceeb xws li semiconductor doping, kho cua sov, thiab ntim tshuaj, txhim kho cov txiaj ntsig thiab zoo.
Ntau yam thiab muaj kev nyab xeeb
Raws li ib qho tsis yog -flammable, non{1}}reactive gas, nws muaj kev nyab xeeb rau ntau yam kev siv, los ntawm pam vov chemicals mus rau purging pipelines thiab reactors.
Cov yam ntxwv ua haujlwm
Lub luag haujlwm tseem ceeb ntawm High-Purity Nitrogen yog los tsim thiab tswj cov huab cua tsis zoo. Nws ua raws li cov pa pam vov kom tshem tawm cov pa oxygen thiab noo noo los ntawm lub taub hau hauv cov tso tsheb hlau luam thiab ntim khoom. Raws li cov pa purging, nws tshem tawm cov huab cua thiab cov kab mob los ntawm cov txheej txheem cov khoom siv thiab cov kav dej ua ntej ua haujlwm lossis nruab nrab ntawm cov khoom hloov pauv. Hauv kev siv tshuaj ntsuam xyuas, nws ua haujlwm raws li cov cab kuj lossis xoom roj. Nws inertness stems los ntawm lub zog triple daim ntawv cog lus ntawm nitrogen atoms, ua rau nws unreactive nyob rau hauv feem ntau tej yam kev mob. Rau cov ntawv thov tseem ceeb, taw tes- ntawm- siv cov purifiers feem ntau ua haujlwm kom ua tiav qib purity kawg uas yuav tsum tau muaj ntawm lub cuab yeej.
Thawj daim ntawv thov teb
Semiconductor & Electronics Manufacturing
Siv nyob rau hauv wafer fabrication rau purging, pam vov, sputtering, thiab raws li ib tug carrier roj. Tseem ceeb rau cov txheej txheem xws li tshuaj vapor deposition (CVD), etching, thiab annealing.
Pharmaceuticals & Biotechnology
Pam pa ntawm oxygen- cov khoom lag luam rhiab heev, purging ntawm reactors thiab filling kab, inerting rau hnyav rov qab, thiab ntim kom ntev txee-lub neej (Modified Atmosphere Ntim - MAP).
Hlau & Kev kho cua sov
Muab cov cua tsis zoo rau kev sib tsoo, sintering, thiab brazing los tiv thaiv kev scaling thiab decarburization ntawm siab - cov nqi hlau.
Analytical & Laboratory
Ua haujlwm raws li cov khoom siv roj hauv Gas Chromatography (GC), ntxuav cov pa hauv Spectroscopy, thiab rau ntsuas ntsuas ntsuas.
Khoom noj & dej haus

Cov neeg siv khoom sib koom tes Case
Ib lub chaw tsim khoom cog lus tsim cov qib siab micro-electromechanical systems (MEMS) sensors rau kev nyab xeeb tsheb tau tawm tsam nrog cov khoom qis qis. Lub hauv paus ua rau tsom xam pom tias cov pa oxygen thiab noo noo nyob rau hauv lawv cov cua sov cua thaum lub sij hawm tseem ceeb annealing kauj ruam tau ua rau oxidation thiab kev ntxhov siab nyob rau hauv lub mos silicon qauv. Peb tau ua raws li cov kev cai siab purity nitrogen mov tov, xa 99.9995% nitrogen nrog lav cov pa oxygen qis dua 1 ppm thiab noo noo qis dua 2 ppm. Peb tsim lub kaw - lub voj xa khoom nrog lub sijhawm tiag tiag - oxygen analyzers ntawm lub qhov cub inlet. Qhov zoo ib yam, ultra{10}}qhuav inert cua los ntawm peb cov purity nitrogen siab tshem tawm qhov teeb meem oxidation. Qhov kev cuam tshuam no tau ua rau 25% nce hauv cov khoom siv ua haujlwm tau txais txiaj ntsig ntawm ib lub wafer thiab txhim kho lub sijhawm ntev - kev ntseeg siab ntawm cov sensors. Qhov kev koom tes no tau ua pov thawj tias peb High{15}}Purity Nitrogen tsis yog tsuas yog siv hluav taws xob xwb tab sis cov txheej txheem tseem ceeb uas ua rau muaj kev tsim khoom siv tom ntej- tiam tom ntej.
