Cov kev sim rau cov khoom siv tshuaj
Jan 12, 2026
High-Kev Ua Haujlwm Ua Kua Dej Chromatography (HPLC): HPLC yog ib ceg tseem ceeb ntawm kev tshuaj xyuas chromatographic. Nws siv cov theem ua kua mobile thiab lub siab - lub zog ua kua xa tawm los tso cov kuab tshuaj ib leeg lossis cov kuab tshuaj sib xyaw nrog cov polarities sib txawv rau hauv kab chromatographic uas muaj cov theem nyob ruaj khov. Cov khoom sib cais nyob rau hauv kem thiab tom qab ntawd kuaj pom los ntawm tus ntes. HPLC yog siv dav hauv kev sib cais thiab kev txiav txim siab ntawm cov khoom xyaw nquag hauv cov zaub mov noj qab haus huv, cov khoom noj muaj zog, cov vitamins, thiab cov proteins.
Ultraviolet Absorption Spectrophotometry (UV): UV nrhiav tau tsuas yog siv rau kev txiav txim siab ntawm complex muaj pes tsawg leeg thiab ruaj khov. Nws ua haujlwm los ntawm kev ntsuas qhov nqus ntawm ultraviolet electromagnetic nthwv dej los ntawm qee qhov valence electrons hauv cov molecules, ua rau muaj kev hloov pauv los ntawm qib qis zog mus rau qib siab zog, yog li tsim cov spectrum. UV kuaj pom tau dav siv hauv kev kuaj cov khoom, tshuaj xyuas cov khoom, thiab cov qauv tsim kho hauv kev lag luam tshuaj.
Gas Chromatography (GC): Gas chromatography cais cov qauv mus rau hauv cov tebchaw sib txawv thiab tshuaj xyuas lawv hauv cov roj chromatograph. Nws yog qhov tsim nyog rau kev txheeb xyuas qhov ntau thiab zoo ntawm ntau yam tsis sib xws.
Infrared Spectroscopy (IR): Infrared spectroscopy kuaj cov qauv raws li cov qauv vibrational molecules, muab cov ntaub ntawv hais txog cov muaj pes tsawg leeg thiab cov qauv ntawm cov qauv hauv cov qauv. Nws yog feem ntau siv rau kev tshuaj ntsuam xyuas cov tshuaj zoo.
Mass Spectrometry (MS): Mass spectrometry ionizes cov tebchaw hauv cov qauv thiab kuaj pom lawv nyob rau hauv ib pawg spectrometer, muab cov ntaub ntawv hais txog qhov hnyav molecular thiab cov qauv ntawm cov tebchaw hauv cov qauv.
Cov txheej txheem tshuaj ntsuam xyuas: Raws li cov tshuaj tiv thaiv tshwj xeeb thiab kev sib raug zoo, cov txheej txheem no tuaj yeem txheeb xyuas ntau yam khoom siv tshuaj thiab muab cov ntaub ntawv txhim khu kev qha thiab cov ntaub ntawv rau kev tsim tshuaj.
Elemental Analyzer: Siv lub siab -kub combustion thermal conductivity tsom xam, nws tuaj yeem txiav txim siab cov ntsiab lus ntawm carbon, hydrogen, nitrogen, sulfur, thiab oxygen hauv cov qauv.
Tsis yog-Txoj kev kuaj kev puas tsuaj: Xws li kev kuaj hluav taws xob (RT), kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), thiab ntsuas kev nkag siab (PT), cov txheej txheem no feem ntau yog siv los kuaj xyuas qhov tsis xws hauv cov khoom.
Lub teeb tawg txoj kev: suav nrog lub teeb dawb thiab laser, siv rau kev soj ntsuam morphological thiab kev tsom xam cov khoom siv.
Thermogravimetric tsom xam: siv los kawm cov kev hloov loj ntawm cov ntaub ntawv thaum cua sov, feem ntau siv los soj ntsuam cov thermal stability thiab decomposition yam ntxwv ntawm cov ntaub ntawv.
