Peb nkag siab txog qhov tseem ceeb ntawm kev tiv thaiv kev ncaj ncees ntawm koj cov biomolecules thiab reagents nrog txoj cai buffering systems.Peb cov buffers lom neeg muab kev ruaj ntseg thiab pH tswj tsis cuam tshuam nrog cov txheej txheem lom neeg, thiab muab cov ntsev tseem ceeb thiab cov as-ham rau cov hlwb thiab cov ntaub so ntswg.Peb cov txheej txheem buffering siab heev tuaj yeem ua rau koj muaj kev ruaj ntseg zoo tshaj plaws hauv kab lis kev cai ntawm tes, polymerase saw tshuaj tiv thaiv (PCR), tshuaj ntsuam xyuas tshuaj, bioprocessing, purification, thiab daim ntawv thov zaum kawg.Tag nrho peb cov khoom tuaj yeem ntsuas los ntawm kev tshawb fawb thaum ntxov mus rau kev lag luam hauv cov qib tsis sib txawv.Peb muab ntau lub ntim ntim, kev cai sib xyaw, thiab txawm tias ua kua.

Peb kuj muab cov kev xaiv dav dav ntawm cov khoom siv biochemical zoo hauv cov qib ua tau zoo thiab ntau yam tshiab, cov neeg siv khoom zoo rau kev ntim khoom.Ntxiv rau cov khoom lag luam tawm ntawm lub txee, peb muab cov kev cai reagent manufacturing, blending thiab ntim kom tau raws li koj xav tau.

Lub hauv paus ntsiab lus ua haujlwm thiab pH tus nqi ntawm cov tshuaj tsis haum Thaum muaj qee cov kua qaub thiab alkali ntxiv rau qee qhov kev daws, nws muaj cov nyhuv cuam tshuam rau pH hloov ntawm cov tshuaj, uas yog hu ua buffering effect.Qhov kev daws teeb meem zoo li no yog hu ua kev daws teeb meem.Kev sib xyaw ntawm cov kua qaub tsis muaj zog thiab lawv cov ntsev (xws li HAc thiab NaAc), thiab cov kev daws teeb meem sib xyaw ntawm cov hauv paus tsis muaj zog thiab lawv cov ntsev (xws li NH3·H2O thiab NH4Cl) yog cov tshuaj tsis haum.Cov nyhuv buffering ntawm cov tshuaj tsis muaj li ntawm cov tsis muaj zog acid HA thiab nws cov ntsev NaA ntawm cov kua qaub yog vim muaj ib tug txaus tus nqi ntawm alkali A- nyob rau hauv cov tshuaj.Thaum muaj qee qhov muaj zog acid ntxiv rau cov tshuaj no, H ions tau pib noj los ntawm A- ions: yog li pH ntawm cov tshuaj yuav luag tsis hloov;Thaum muaj qee qhov muaj zog hauv paus ntxiv, qhov tsis muaj zog acid HA tam sim no hauv cov tshuaj siv OH-ions cuam tshuam qhov kev hloov pauv ntawm pH.
