Crownpak cr-i +

WebThe crown ether selectors are immobilized on 5um silica support. Immobilization extends the range of solvents used for mobile phases such as acetonitrile and ethanol, thereby enhancing enantioselective resolution of chiral compounds. Use of the immobilized CROWNPAK CR-I(+) & CR-I(-) selectors also provides longer column life time.

WebDaicel Chiral Technologies BioPharma & Academic Research WebJul 26, 2024 · MS/MS detects the peaks of l-Gln and d-Lys as an identical compound with CROWNPAK CR-I(+) because they have the same MRM transition and similar retention time. To solve this problem, CROWNPAK CR-I(−) is used since the elution order of enantiomers can be reversed, which allows the analysis of l-Gln/ d-Lys and d-Ile/ d-allo-Ile. farm style living room decor https://fantaskis.com
