Qhov sib txawv tseem ceeb ntawm kev lim dej thiab cov khoom seem yog cov lim dej yog cov kua dej, qhov seem yog cov khoom muaj nyob hauv qhov raug ncua.
Hauv luv luv, cov lim dej yog cov kua uas tuaj yeem dhau los ntawm lub lim. Yog li ntawd, nws yog qhov peb tau txais tom qab lim tawm qhov raug ncua. Residue, ntawm qhov tod tes, yog cov khoom loj uas peb tau txais ntawm cov ntawv lim tom qab lim tawm qhov kev ncua. Peb feem ntau siv cov ntsiab lus no thaum peb tham txog cov txheej txheem analytical, filtration. Filtration yog ib txoj kev sib cais. Nws tuaj yeem ua rau lom neeg, lub cev lossis kev sib cais.
filtrate yog dab tsi?
Cov lim yog cov kua dej uas peb tuaj yeem tau txais tom qab kev pom. Nws yog cov kua dej uas dhau los ntawm cov ntawv lim peb siv rau kev pom. Kev lim dej yog cov txheej txheem tshuaj ntsuam peb tuaj yeem siv los cais cov kua dej los ntawm cov khoom ntawm qhov raug ncua.

Txawm li cas los xij, nyob ntawm qhov loj ntawm qhov pores ntawm daim ntawv lim thiab qhov loj ntawm cov khoom uas muaj nyob rau hauv kev ncua, qee qhov zoo tuaj yeem dhau los ntawm cov ntawv lim; Yog li ntawd, peb tuaj yeem soj ntsuam qee qhov zoo hauv cov filtrate. Hauv cov xwm txheej zoo li no, peb hais tias cov lim dej tsis huv. Ntawm no, kev sib cais tsis tiav. Txawm hais tias cov filtrate feem ntau yog kua, muaj qee lub sijhawm uas cov filtrate tuaj yeem ua tau roj lossis txawm tias cov kua dej supercritical.

Dab tsi yog Residue?
Cov seem yog cov khoom uas peb tuaj yeem tau txais tom qab kev pom zoo. Thaum xub thawj, cov khoom raug tshem tawm hauv cov tshuaj uas peb yuav mus lim. Cov khoom seem raug kaw rau ntawm daim ntawv lim thaum lub sij hawm pom. Tom qab nchuav cov tshuaj tag nrho los ntawm cov ntawv lim, peb tuaj yeem tau txais tag nrho cov khoom seem, uas muaj nyob rau hauv cov tshuaj.
Peb tuaj yeem siv ntau txoj hauv kev los cais cov khoom sib txawv hauv cov khoom sib tov. Piv txwv li, nyob rau hauv txoj kev pom lub cev, cov khoom loj loj tseem nyob ntawm lub lim; Hauv cov txheej txheem kev lim dej lom neeg, peb tuaj yeem tau txais cov khib nyiab xws li metabolites thiab cov cell sib txawv.
Dab tsi yog qhov sib txawv ntawm Cov Lim thiab Cov Khoom Siv?
Lim thiab residue yog cov khoom peb tau txais tom qab txheej txheem pom. Qhov sib txawv tseem ceeb ntawm filtrate thiab residue yog qhov filtrate yog cov kua dej, whereas cov residue yog cov khoom muaj nyob rau hauv ib qho kev ncua. Lim cais ob feem ntawm ib leeg thiab los ntawm kev ua kom huv ntxiv, peb tuaj yeem tau txais cov khoom ntshiab. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm kev lim dej thiab cov khoom seem yog qhov filtrate tuaj yeem yog roj lossis kua, tab sis cov seem yog ib txwm nyob hauv lub xeev khov kho.
Thaum xav txog cov khoom kawg ntawm cov txheej txheem pom, peb tuaj yeem tau txais cov lim dej raws li cov kua dej paug nrog cov khoom zoo, thiab peb tuaj yeem tau txais cov khoom seem raws li cov khoom uas muaj cov kua dej ntxiv rau ntawm qhov chaw. Piv txwv li, cov dej haus tau los ntawm cov dej lim dej, cov ntshav cov ntshav, thiab lwm yam yog qee qhov piv txwv rau cov filtrates, whereas crystals uas tsim thaum lub sij hawm tshuaj tiv thaiv uas tshwm sim los ntawm lub cev filtration, metabolites tau los ntawm biofiltration, thiab lwm yam yog piv txwv rau residue.
Summary – Lim vs Residue
Hauv cov ntsiab lus, cov lim dej thiab cov seem yog cov khoom uas peb tau txais tom qab kev pom. Qhov twg, qhov sib txawv tseem ceeb ntawm filtrate thiab residue yog qhov filtrate yog kua, whereas cov residue yog ib qho khoom muaj nyob rau hauv lub ncua kev kawm ntawv. Ib qho kev ncua muaj ob ntu no ua ke. Kev lim cais ob feem ntawm ib leeg thiab los ntawm kev ua kom huv ntxiv, peb tuaj yeem tau txais cov tshuaj ntshiab.
