Cov qib zoo ntawm cov tshuaj reagents yog complex, thiab muaj ntau ntau yam, uas yog tshwj xeeb yog tsis meej pem. Muaj 225 hom kab lus dav dav (ib chav kawm ntawm reagents), uas yog qhov tseem ceeb ntxiv hauv Tuam Tshoj lub nroog Beijing, Tianjin, Shanghai, Xi'an, Chengdu, Guangzhou thiab Shenyang tshuaj reagent puag. Qhov thib ob hom reagent yog siv nyob rau hauv yuav luag tag nrho cov teb, thiab nws kuj yog ib tug tsim nyog ntau yam rau manufacturers, muaj txog 1800 ~ 2000 ntau yam, thiab xws li reagents yog nyob rau hauv siab thov thiab dav siv. Muaj li ntawm 3000 ~ 6000 ntau yam ntawm peb hom reagents, thiab feem ntau ntawm lawv cov kev siv yog muaj feem xyuam rau lub teb chaws kev lag luam thiab tib neeg lub neej, xws li tshuaj lom neeg, metallurgy, hluav taws xob fais fab, khoom noj khoom haus, tshuaj thiab kev noj qab haus huv thiab lwm yam lag luam uas yog siv tshwj xeeb. hauv kev lag luam.
Nyob rau hauv Suav teb, muaj 225 hom tshuaj reagents qhia nyob rau hauv peb qib: zoo heev purity, analytical purity, thiab tshuaj purity, raws li lub teb chaws tus qauv ntawm cov neeg koom pheej ntawm Tuam Tshoj thiab cov qauv muab los ntawm lub qub Ministry of Chemical Industry. Cov 225 hom tshuaj reagents no qhia lub hauv paus ntawm cov ntsiab lus ntawm cov tshuaj reagents nyob rau hauv Tuam Tshoj raws li cov qauv. Cov ntsiab lus ntawm lwm yam tshuaj yog txiav txim los ntawm lub hauv paus no, thiab nws cov ntsiab lus yog txiav txim los ntawm kev ntsuas. Yog li ntawd, qhov zoo ntawm cov tshuaj reagents no tseem ceeb heev. Nyob rau tib lub sijhawm, cov 225 tshuaj reagents tau dhau los ua ntau yam vim lawv siv ntau yam. Cov 225 ntau yam no tau raug cim rau hauv cov tshuaj reagent catalog. Tsis tas li ntawd, muaj cov reagents tshwj xeeb, uas yog tsim nyob rau hauv ntau me me, yuav luag ntawm qhov kev thov, thiab lawv cov ntau yog feem ntau teev los ntawm tus neeg siv.
Cov qib zoo sib xws
Superior Grade Pure (GR, Green Label): Cov ntsiab lus tseem ceeb ntawm cov ntsiab lus siab thiab purity siab, haum rau kev txheeb xyuas thiab kev tshawb fawb ua haujlwm, thiab qee qhov tuaj yeem siv los ua cov khoom siv.
Analytical Purity (AR, Red Label): Cov ntsiab lus tseem ceeb ntawm cov ntsiab lus, siab purity, tsis muaj kev cuam tshuam impurities, haum rau kev lag luam tsom xam thiab kev sim tshuaj. Sib npaug rau ACS chav kawm (American Chemical Society standard)
Chemically ntshiab (CP, xiav daim ntawv lo): cov ntsiab lus siab ntawm cov ntsiab lus tseem ceeb, siab purity, thiab cuam tshuam impurities, haum rau kev sim tshuaj thiab kev npaj hluavtaws.
Experimental Purity (LR, Yellow Label): Cov ntsiab lus siab ntawm cov khoom tseem ceeb, tsis zoo purity, thiab impurity cov ntsiab lus tsis raug xaiv, uas tsuas yog tsim nyog rau kev sim tshuaj lom neeg thiab kev npaj hluavtaws.
Qhov taw qhia thiab stains (ID lossis SR, daim ntawv lo ntshav): Yuav tsum muaj qhov tshwj xeeb rhiab heev.
Qib Qib (ZD): Cov tshuaj reagents customized rau cov neeg siv tshwj xeeb raws li cov kev tswj xyuas zoo uas cov neeg siv xav tau.
Electron Pure (MOS): Tsim nyog rau kev tsim cov khoom siv hluav taws xob uas tsis tshua muaj hluav taws xob tsis huv.
Sib npaug reagents (3N, 4N, 5N): cov ntsiab lus tseem ceeb ntawm cov khoom muaj ntau dua 99.9%, 99.99% thiab 99.999%, feem.
Spectral purity: 99.99% purity ntawm lub ntsiab Cheebtsam
