一般說明

硅藻土[Celite 545 AW]被认为是由于沉降沉积而形成的单细胞藻类/硅藻的骨架残留。DE是一种表面活性剂,其可引起表皮脂质的磨损和吸附。[1]DE是一种化学农药的有效替代品。[2]DE是无定形二氧化硅,将其粉碎并煅烧可形成方石英。[3]
试剂级Celite® 545 AW。经过酸洗和高纯度助熔煅烧的硅藻土,特别适用于色谱和其他实验室应用。

應用

  • 在使用制备色谱进行荞麦酚的纯化过程中,Celite® 545AW可用作固定相。[4]
  • Celite® 545AW可用作分馏过程的包装材料,并且馏分可通过GC-ECD、GC/ECNI-MS[5]、以及IC-MS/MS进行分析。[6]

The molecular structure of fagopyritol A1, a novel galactopyranosyl cyclitol from buckwheat seeds, was determined to be O-alpha-D-galactopyranosyl-(1 --> 3)-D-chiro-inositol by 1H and 13C NMR. Fagopyritol A1 is a positional isomer of fagopyritol B1 (O-alpha-D-galactopyranosyl-(1 --> 2)-D-chiro-inositol), representing a different
