WebThe similarities between CHIRALPAK IA and IB and the other columns lie in the chiral selector. Both columns are based on the same chiral selectors as CHIRALPAK AD-H and CHIRALCEL OD-H®: the 3,5-dimethylphenylcarbamate derivative of amylose and cellulose, respectively. CHIRALPAK IC, on the other hand, has a totally new chiral selector WebUSP L40対応. CHIRALCEL Ⓡ OD-3/OD-H/ODは、セルロース誘導体(Cellulose tris(3,5-dimethylphenylcarbamate))をシリカゲル担体にコーティングした固定相を使用してい …
