一般說明
Ascentis 系列色谱柱是 Supelco 科学家推出的第四代 HPLC 色谱柱技术。Ascentis 系列色谱柱是以高纯硅胶为基质，孔径 100Å，硅胶粒径为 3、5 和 10 微米。该色谱柱用于小分子的应用，柱内径可从微径柱（1.0mm 内径）扩展到制备尺寸（50mm 内径）。该系列包括 C18、C8、苯基、Si 和内嵌极性基团相（反相酰胺）。
Ascentis Si 是具有高载样量和优良峰形的硅胶柱。Ascentis Si 在正相和 HILIC/ANP（水性正相）模式下都可使用。

A new method for the simultaneous determination of ozone and carbonyls in air using a two-bed cartridge system has been developed. Each bed consists of reagent-impregnated silica particles. The first contains trans-1,2-bis-(4-pyridyl) ethylene (BPE) while the second contains 2,4-dinitrophenylhydrazine (DNPH).

Nucleoside triphosphate diphosphohydrolase (NTPDase) is an enzyme belonging to the apyrase family that participates in the hydrolysis of the nucleosides di- and triphosphate to the corresponding nucleoside monophosphate. This enzyme underlies the virulence of parasites such as Leishmania. Recently, an
