Product Detail

Khoom cim npe

B&M NH2 (amino) yog aminopropyl extraction kem nrog silica gel. Nws muaj qhov tsis muaj zog polar nyob ruaj ruaj theem thiab anion exchanger, los ntawm qaug zog anion pauv (aqueous tov) los yog polarity adsorption (non-polar organic tov) kom ncav cuag cov nyhuv, yog li muaj ob lub luag haujlwm. Thaum npaj nrog nonpolar daws, xws li n-hexane, nws tuaj yeem tsim hydrogen bonds nrog molecules nrog -oh, -nh los yog -sh, thiab amino PKa = 9.8; Cov nyhuv ntawm anion tsis muaj zog dua li ntawm SAX, thiab hauv PH < 7.8 aqueous tov, nws yuav siv tau raws li ib tug tsis muaj zog anion pauv tus neeg sawv cev, uas yuav siv tau los tshem tawm cov muaj zog anions xws li sulfonic acid nyob rau hauv cov qauv.

Cov aminopropyl daim ntawv cog lus yog qhov zoo tshaj plaws polar adsorbent nyob rau hauv nonpolar organic tov thiab muaj ib tug tsis muaj zog anion-pauv retention nyob rau hauv aqueous kua.NH2 ua tau zoo nyob rau hauv ntau yam ntawm cov qauv substrates thiab yuav siv tau nyob rau hauv cov zaub mov, ib puag ncig, tshuaj thiab tshuaj.

Daim ntawv thov:
Av; Dej; Cov kua dej hauv lub cev (plasma / zis thiab lwm yam); Khoom noj khoom haus
Tej kev siv:
Cov anions muaj zog, xws li sulfonate, yog
muab rho tawm hauv pH <7.8 aqueous tov
Extraction thiab sib cais ntawm isomers
Phenol, phenolic pigments, natural khoom
Petroleum feem; Qab Zib; Tshuaj thiab lawv
