Hauv chromatography , daws teeb meem yog ib qho kev ntsuas ntawm kev sib cais ntawm ob lub ncov ntawm qhov sib txawv tuav lub sij hawm t hauv a chromatogram.

Hais txog qhov no, kev daws teeb meem txhais li cas hauv chromatography?

Kev daws teeb meem . Cov daws teeb meem ntawm ib elution yog ib qho kev ntsuas ntawm qhov zoo npaum li cas ob elution peaks ua tau yuav txawv hauv a chromatographic kev sib cais. Nws yog txhais raws li qhov sib txawv ntawm lub sijhawm khaws cia ntawm ob lub ncov, muab faib los ntawm kev sib xyaw ua ke ntawm cov elution peaks.

Tsis tas li ntawd, lub siab daws teeb meem roj chromatography yog dab tsi? LIQUID CHROMATOGRAPHY – GAS CHROMATOGRAPHY Siab daws teeb meem roj chromatography (HRGC) yog cov txheej txheem tsim nyog tshaj plaws rau kev tshuaj xyuas cov tshuaj tsis haum tshuaj. Kev taw qhia ntawm loj tus nqi ntawm cov kuab tshuaj mus rau hauv a GC kem yuav tsum tau siv cov txheej txheem tshwj xeeb los cais cov kuab tshuaj los ntawm cov qauv xaiv.

Dhau li ntawm no, koj pom qhov kev daws teeb meem ntawm GC li cas?

Kev sib npaug (1) qhia tias lub daws teeb meem yog qhov sib txawv ntawm cov sij hawm khaws cia tau muab faib los ntawm qhov nruab nrab ncov dav. Nyob rau hauv lub ncov nrog Gaussian faib, lub ncov dav yog W = 4 σ (qhov twg σ yog tus qauv sib txawv) thiab lub ncov FWHM yog W0.

Qhov kub li cas cuam tshuam txog kev daws teeb meem hauv cov roj chromatography?

Nce tus cab kuj gas flow rate thiab/los yog kub yuav xa cov vapors mus rau hauv kem sai dua, uas yuav txo lub sij hawm tuav thiab ua phem rau daws teeb meem . Txo cov kub thiab/lossis tus nqi ntws nce lub sij hawm tuav thiab broadens lub peaks.
