Feem ntau, Cov no yog HPLC qib dej (Mili Que), methanol, acetone, benzene, acetonitrile, chloroform thiab Petroleum ether.
Cov kua dej twg siv hauv HPLC?
Sorbent hais tej zaum yuav hydrophobic los yog polar nyob rau hauv cov xwm. Cov theem txawb uas siv tau suav nrog kev sib xyaw ua ke ntawm dej nrog ntau cov kuab tshuaj organic (feem ntau yog acetonitrile thiab methanol). Qee cov txheej txheem HPLC siv cov theem tsis muaj dej tsis muaj dej (saib cov theem chromatography hauv qab no).
HPLC cov kuab tshuaj qib yog dab tsi?
HPLC qib cov kuab tshuaj yog npaj los ntawm cov txheej txheem distillation kom tshem tawm cov impurities tsis haum raws li kev pom kom ua tiav cov kuab tshuaj purity siab… particle mus txog 0.02 micron ib. Cov kuab tshuaj no muaj UV-absorption tsawg thiab tsis tshua muaj siab cuam tshuam.
Kuv yuav xaiv cov kuab tshuaj rau HPLC li cas?
kev txiav txim siab tseem ceeb hauv HPLC cov kuab tshuaj xaiv
- Nyiaj. Tus nqi yog ib qho tseem ceeb rau kev txiav txim siab vim HPLC xav tau cov kuab tshuaj purity qib siab dua thiab nws yog ib qho uas pom ntau lub HPLC lub tshuab ua haujlwm nyob ib ncig ntawm lub moos hauv chav kuaj loj. …
- Solubility. …
- Txhob Cia Siab. …
- Volatility. …
- Viscosity. …
- Kev tsis sib haum. …
- dej.
Vim li cas cov kuab tshuaj sib tov siv hauv HPLC?
Binary hnyav sib tov yog siv los ua cov nqa hauv HPLC kab txhawm rau rho tawm cov tshuaj thiab cov tshuaj ua ntej thaum lub sijhawm tsim khoomKev tswj xyuas qhov tseeb ntawm cov khoom sib xyaw yog qhov tseem ceeb rau kev sib cais kom raug thiab ua tau zoo ntawm qhov xav tau cov tshuaj sib txuas.
