Chromatography yog ib txoj kev siv los ntawm cov kws tshawb fawb rau kev cais cov organic thiab inorganic tebchaw kom lawv tuaj yeem txheeb xyuas thiab kawm. Chromatography yog siv nyob rau hauv ntau yam sib txawv. Qee tus neeg siv chromatography kom paub seb dab tsi yog nyob rau hauv ib qho khoom los yog kua. Nws kuj yog siv los txiav txim seb yam khoom tsis paub yog dab tsi.
Tsis tas li ntawd, kev siv chromatography yog dab tsi?
Chromatography yog siv nyob rau hauv cov txheej txheem kev lag luam los ntxuav cov tshuaj, kuaj cov kab ntau ntawm cov tshuaj, cais cov chiral compounds thiab cov khoom kuaj rau kev tswj kom zoo. Chromatography yog cov txheej txheem ntawm lub cev los ntawm kev sib xyaw ua ke sib cais lossis txheeb xyuas.
Qhov thib ob, chromatography siv los daws cov teeb meem txhaum cai li cas? Keeb kwm: Chromatography yog ib txoj hauv kev los tshuaj xyuas cov khoom sib tov los ntawm kev sib cais rau hauv cov tshuaj uas lawv tau tsim. Cov kws tshawb fawb forensic muaj peev xwm siv tus cwj mem chromatography rau daws teeb meem txhaum cai los ntawm kev sib piv cov ntaub ntawv los yog stains pom ntawm a kev ua txhaum scene rau tus cim lossis cwj mem uas yog tus neeg raug liam.
Tsis tas li ntawd, vim li cas chromatography tseem ceeb?
Chromatography play ib tseem ceeb lub luag hauj lwm nyob rau hauv ntau yam kev lag luam tshuaj thiab kuj nyob rau hauv cov tshuaj thiab zaub mov kev lag luam. Chromatography yog siv rau kev soj ntsuam zoo thiab checker hauv kev lag luam khoom noj khoom haus, los ntawm kev txheeb xyuas thiab sib cais, txheeb xyuas cov additives, vitamins, preservatives, proteins, thiab amino acids.
Cov txheej txheem ntawm chromatography yog dab tsi?
Chromatography Qhov tseeb yog ib txoj hauv kev ntawm kev sib cais tawm ntawm cov tshuaj sib tov, uas yog nyob rau hauv cov roj los yog kua daim ntawv, los ntawm kev cia lawv nkag mus maj mam dhau los ntawm lwm yam khoom, uas feem ntau yog kua los yog khoom. Raws li lub sij hawm mobile txav, nws cais tawm mus rau hauv nws cov khoom nyob rau theem nyob ruaj khov.

Nyias txheej chromatography txawv ntawm daim ntawv chromatography li cas?
Qhov sib txawv ntawm cov txheej nyias nyias chromatography (TLC) thiab ntawv chromatography (PC) yog tias, thaum lub sij hawm nyob ruaj ruaj hauv PC yog ntawv, cov theem nyob ruaj khov hauv TLC yog txheej nyias ntawm cov khoom siv tsis zoo uas txhawb nqa ntawm lub tiaj tus, tsis muaj zog
Tub ceev xwm siv chromatography li cas?
Hauv forensics, tub ceev xwm siv chromatography los txheeb xyuas thiab tshuaj xyuas cov khoom pom ntawm qhov chaw ua txhaum cai. Txhua qhov sib tov yog tsim los ntawm cov tshuaj molecules ntawm cov tshuaj sib txawv, hauv ntau qhov sib txawv. Chromatography ua haujlwm los ntawm kev sib cais cov tshuaj tawm ntawm qhov sib tov thiab kawm seb cov molecules coj li cas thaum lub sijhawm sib cais
Thaum twg yuav siv chromatography?
Chromatography yog siv nyob rau hauv cov txheej txheem kev lag luam los ntxuav cov tshuaj, kuaj cov kab ntau ntawm cov tshuaj, cais cov chiral compounds thiab kuaj cov khoom rau kev tswj kom zoo. Chromatography yog cov txheej txheem ntawm lub cev los ntawm kev sib xyaw ua ke sib cais lossis tshuaj xyuas
Koj yuav ua li cas cais cov khoom ntawm tus cwj mem siv chromatography?
Txhawm rau ua tus cwj mem chromatography, koj muab ib qho me me ntawm tus cwj mem kom sib cais ntawm ib kawg ntawm ib daim ntawv lim dej. Qhov kawg ntawm daim ntawv strip yog muab tso rau hauv ib qho hnyav. Cov kuab tshuaj txav mus rau ntawm daim ntawv thiab, thaum nws nce mus, nws dissolves cov tshuaj sib tov thiab rub lawv mus rau hauv daim ntawv
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
