Hauv gas chromatography , tus cab kuj gas yog theem mobile. Tus nqi ntws ntawm cov cab kuj tau ua tib zoo tswj kom muab qhov kev sib cais meej tshaj plaws ntawm cov khoom hauv cov qauv. Raws li tus qauv cais tawm thiab nws cov ntsiab lus cov pa taug kev raws kab ntawm qhov sib txawv speeds, adetector senses thiab kaw lawv.
Hauv qhov no, roj chromatography siv rau dab tsi?
Gas chromatography ( GC ) yog ib hom kev chromatography siv nyob rau hauv analytical chemistry forseparating and analyzing compounds that can be vaporized without decomposition. Hom siv ntawm GC suav nrog kev ntsuam xyuas qhov purity ntawm ib yam khoom, los yog cais cov khoom sib txawv ntawm cov khoom sib tov.
Kuj Paub, roj chromatography siv sijhawm ntev npaum li cas? Raws li txoj cai ntawm tus ntiv tes xoo, qhov ntsuas kub me ntsis siab tshaj qhov nruab nrab ntawm qhov kub ntawm cov qauv ua rau lub sijhawm elution ntawm 2-30 feeb.
chromatography yog dab tsi thiab nws ua haujlwm li cas?
Chromatography yog siv los cais cov khoom sib tov rau hauv lawv cov khoom. Txhua yam ntawm chromatography ua haujlwm ntawm tib txoj cai. Lawv txhua tus muaj cov theem nyob ruaj khov (asolid, lossis cov kua dej txhawb nqa ntawm cov khoom) thiab theem mobile (kua kua lossis roj). Cov khoom sib txawv taug kev ntawm qhov sib txawv.
Gas chromatography cais cov tebchaw li cas?
Rau cais tus tshuaj sib xyaw hauv gas - kua dej chromatography , ib qho kev daws teeb meem uas muaj cov organic tshuaj sib xyaw ntawm kev txaus siab yog txhaj rau hauv qhov chaw nres nkoj uas nws yuav ua vaporized. Hauv GLC, cov kua dej nyob ruaj khov yog adsorbed mus rau ib qho khoom inertpacking los yog immobilized ntawm cov phab ntsa capillary tubing.

Rheostat yog dab tsi thiab nws ua haujlwm li cas?
Lub rheostat yog qhov sib txawv ntawm cov resistor uas yog siv los tswj tam sim no. Lawv muaj peev xwm sib txawv qhov kev tawm tsam hauv ib lub voj voog yam tsis muaj kev cuam tshuam. Rheostats feem ntau yog siv los ua cov cuab yeej tswj fais fab, piv txwv li los tswj lub teeb siv (dimmer), ceev ntawm lub cev muaj zog, lub tshuab cua sov thiab qhov cub
Kev tiv thaiv yog dab tsi thiab nws ua haujlwm li cas?
Kev tsis kam yog qhov cuam tshuam rau qhov ntws ntawm electrons hauv cov khoom. Txawm hais tias muaj peev xwm sib txawv thoob plaws tus neeg xyuas pib txhawb qhov ntws ntawm electrons, tsis kam ua rau nws poob siab. Tus nqi ntawm cov nqi ntws ntawm ob lub davhlau ya nyob twg yog qhov sib xyaw ntawm ob yam no
Cov txheej nyias nyias chromatography yog dab tsi thiab nws ua haujlwm li cas?
Nyias-txheej chromatography (TLC) yog ib qho txheej txheem chromatography siv los cais cov khoom sib xyaw uas tsis yog-volatile. Tom qab cov qauv tau siv rau ntawm lub phaj, cov kuab tshuaj los yog cov kuab tshuaj sib tov (lub npe hu ua lub sijhawm txawb) yog kos rau ntawm lub phaj ntawm capillary nkaus
Dab tsi yog chromatography thiab nws ua haujlwm raws nraim li cas?
Chromatography yog ib txoj hauv kev ntawm kev sib cais ntawm cov tshuaj sib tov, uas yog nyob rau hauv cov roj los yog kua daim ntawv, byletting lawv maj mam dhau los ntawm lwm yam khoom, uas feem ntau yog ib tug kua los yog khoom
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
