Chromatography yog siv nyob rau hauv cov txheej txheem kev lag luam los ntxuav cov tshuaj, kuaj xyuas cov kab mob ntawm cov khoom, cais cov chiral compounds thiab cov khoom siv 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.
Tsis tas li ntawd, thaum twg tuaj yeem siv daim ntawv chromatography?
Nws yog siv nyob rau hauv sequencing ntawm DNA thiab RNA. Daim ntawv chromatography yog siv raws li cov txheej txheem analytical chemistry zoo rau kev txheeb xyuas thiab sib cais cov xim sib xyaw zoo li pigments. Nws yog siv hauv kev tshawb fawb tshawb fawb los txheeb xyuas cov organic thiab inorganic tebchaw tsis paub los ntawm kev sib xyaw.
Tsis tas li ntawd, dab tsi yog chromatography siv rau hauv kev lag luam? Chromatography yog siv rau kev tswj kom zoo hauv cov khoom noj kev lag luam , los ntawm kev sib cais thiab tshuaj xyuas cov additives, vitamins, preservatives, proteins, thiab amino acids. Nws tseem tuaj yeem cais thiab txheeb xyuas cov kab mob xws li aflatoxin, cov tshuaj ua rau mob qog noj ntshav uas tsim los ntawm cov pwm ntawm cov txiv laum huab xeeb.
Ib tug kuj yuav nug, vim li cas chromatography tseem ceeb?
Chromatography play ib tseem ceeb Lub luag haujlwm hauv ntau lub lag luam kws tshuaj thiab tseem nyob hauv kev lag luam tshuaj thiab zaub mov. 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.
Lub hauv paus ntsiab lus ntawm daim ntawv chromatography yog dab tsi?
Txoj cai ntawm daim ntawv chromatography : Cov txoj cai koom nrog yog muab faib chromatography nyob rau hauv cov tshuaj yog muab faib los yog partitioned ntawm cov kua theem. Ib theem yog cov dej, uas yog tuav nyob rau hauv lub pores ntawm lub lim ntawv siv; thiab lwm yam yog lub sij hawm mobile uas txav mus rau lub ntawv.

Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav ua li cas koj paub thaum twg yuav siv brackets los yog parentheses interval notation?
Nws yog ib hom kev sau ntawv uas sawv cev rau qhov nruab nrab nrog ib khub ntawm tus lej. Cov kab lus thiab cov brackets yog siv los qhia seb puas yog ib qho ntsiab lus tsis suav nrog. Ib qho kev sib dhos yog siv thaum lub ntsiab lus lossis qhov muaj nuj nqis tsis suav nrog hauv lub sijhawm, thiab siv lub bracket thaum tus nqi suav nrog
Thaum twg koj yuav tsum siv cov haujlwm series koj siv nws li cas?
Nws yog siv los txiav txim siab cov khoom ntawm ib qho kev hloov pauv, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv koob. Kev ua yeeb yam ntawm qee cov hlau ntau dua, teev nyob rau hauv qhov kev txiav txim qis ntawm reactivity
Yuav ua li cas tshwm sim rau ib tug ionic siv lead ua thaum lub zog siv?
Txawm hais tias ionic crystals tau tuav ua ke los ntawm electrostatic zog, cov ions tau sib cais thaum cov khoom yaj. Ions muaj zog txaus nyiam rau qhov kawg ntawm cov polar molecules uas muaj nqi rov qab rau cov ions
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
