1. Gas chromatography-mass spectrometry (GC-MS) gas chromatograph yog tsuas yog siv rau kev tshawb nrhiav cov organic tshuaj, thiab siv rau ib puag ncig geochemistry, organic geochemistry, life science thiab lwm yam kev tshawb fawb, xws li av, huab cua, dej organic pollutants, organochlorine tshuaj tua kab residue tsom xam, organophosphorus tshuaj tua kab residue tsom xam, tshuaj tua kab residue tsom xam, tshuaj ntsuab residue tsom xam, thiab lwm yam. GC muaj qhov zoo ntawm siab rhiab heev, muaj zog selectivity, yooj yim thiab ceev khiav hauj lwm rau kev tshawb nrhiav cov organics uas yooj yim rau gasify thiab tsis yooj yim rau decompose. tom qab gasification. Mass spectrometry (MS) muaj rhiab heev, xaiv thiab kev ntseeg tau. Kev sib xyaw ua ke ntawm MS thiab GC tuaj yeem siv tag nrho lawv cov txiaj ntsig kom ua tiav kev sib cais thiab kev txheeb xyuas sai.
2. Kev ua haujlwm siab ua kua chromatograph tuaj yeem ua rau cov khoom tsis hloov pauv nrog thermal stability tsis zoo uas tsis tuaj yeem txheeb xyuas los ntawm GC-MS. Ntau tshaj 70 feem pua ntawm cov organic tebchaw tuaj yeem txheeb xyuas los ntawm kev ua haujlwm siab ua kua chromatography, tshwj xeeb tshaj yog kev sib cais thiab kev soj ntsuam ntawm cov tebchaw nrog kub kub taw tes, macromolecule, muaj zog polarity thiab tsis zoo thermal stability, qhia qhov zoo.
3. ICP-MS txoj kev yog ceev, raug thiab ruaj khov. Nws yog dav siv nyob rau hauv kev tsom xam ntawm kab kawm, tsis tshua muaj lub ntiaj teb cov ntsiab lus thiab cov hlau hnyav hauv kev tiv thaiv ib puag ncig, geology, metallurgy thiab lwm yam kev lag luam, xws li dej, cua thiab av. Nws yog siv nyob rau hauv geology los txiav txim cov kab thiab ultra-trace hlau ntsiab xws li pob zeb, minerals thiab inclusions, thiab ib co halogen ntsiab thiab non-metallic ntsiab.
4. Inductively coupled plasma-emission spectrometer (ICP-OES) feem ntau yog siv rau kev txiav txim siab ntawm cov ntsiab lus ntawm cov ntsiab lus tseem ceeb thiab qee cov kab hauv ib puag ncig dej, pob zeb, minerals, av, dej sediments, cov khoom siv tshuaj thiab lwm yam qauv.
5. Lub ion chromatograph feem ntau yog siv rau kev soj ntsuam ntawm ib puag ncig cov qauv, nrog rau kev tsom xam ntawm anions thiab cations hauv cov dej saum npoo av, dej haus, dej nag, dej phwj hauv tsev thiab cov dej khib nyiab, kua qaub sediment thiab atmospheric particulates, thiab kab impurities hauv dej thiab reagents. muaj feem xyuam rau kev lag luam microelectronics. Tsis tas li ntawd, nws kuj tau siv dav hauv kev ua zaub mov, kev huv huv, petrochemical, dej thiab geology.
6. Txheeb xyuas cov hlau hnyav hnyav hauv qhov chaw ntawm atomic fluorescence spectrometer, thiab cov khoom xws li AS, Sb, Bi, Hg, Se, Ge hauv dej thiab av.
7. Lub atomic absorption spectrometer muaj feem xyuam rau qhov kev txiav txim ntawm ze li ntawm 70 kab lus thiab yog dav siv nyob rau hauv metallurgy, geology, roj av, tshuaj, kev ua liaj ua teb, chaw kho mob, biochemical thiab ib puag ncig tiv thaiv teb.
