Kev degassing hauv online yog qhov tseem ceeb thaum ua HPLC, FPLC, GPC, thiab uHPLC vim degassing yuav tshem tawm cov pa yaj yog li zam tsis txhob tsim npuas… Tsis tshua muaj siab sib xyaw: cov tshuab muaj ntau dua ua npuas tsim. Cov kuab tshuaj siv rau theem txawb tau sib xyaw ua ntej lub twj tso kua mis.

Vim li cas degassing tseem ceeb?

Degassing yog ib kauj ruam tseem ceeb tom qab sib tov (qee zaum degassing kuj yuav tsum tau tom qab casting) txhawm rau tshem tawm cov pores seem hauv cov slurry Cov pores no tuaj yeem qhia tau thaum sib tov lossis tshuaj tiv thaiv., los yog lawv tuaj yeem tsim los ntawm huab cua nkag thaum lub sij hawm casting.

Dab tsi yog siv Degassers hauv kev kub siab ua kua chromatography?

Thaum kev sib xyaw ua ke ntawm daim nyias nyias nyias, lub tshuab nqus tsev, thiab lub sijhawm nyob hauv, lub hauv-kab degasser tshem tawm cov pa roj txaus kom tsis txhob tawm mus kom lub twj tso kua mis LC yuav ua haujlwm. ntseeg tau.

Degassing unit hauv HPLC yog dab tsi?

HPLC Degassing Units

Tshem cov roj yaj hauv cov theem ntawm cov xov tooj ntawm tes yog ib kauj ruam tseem ceeb rau kev ua kom muaj kev ua haujlwm zoo ntawm lub twj tso kua mis check li qub, thiab tiv thaiv kom tsis txhob muaj cov pa tawm hauv lub ntsuas dej ntws. cell. Cov chav degassing muaj txiaj ntsig zoo degassing nyob rau hauv lub ntim qis, compact tsim.

Yuav ua li cas yog txoj kev siv rau cov kuab tshuaj degassing hauv HPLC?

Ob txoj kev siv dav tshaj plaws los degas lub sijhawm txawb yog: Helium purging: helium yog npuas los ntawm cov kuab tshuaj thiab tshem tawm txog li 80% ntawm cov cua yaj. Nqus degassing: cov kuab tshuaj raug rau lub tshuab nqus tsev thiab qhov txo qis tshem tawm ntau tshaj 60% ntawm cov cua yaj.
