10 The main and relatively constant components of SLP, saikosaponins a, saikosaponins d, rutin and hesperidin were used for quality control by high-performance liquid chromatography.10 Complete Freund's adjuvant: CFA is composed of paraffin oil, mannide monooleate and heat-killed, dried Bacillus ...
Further purification of the active principle is achieved by chromatography, for example in a silica column, Sephadex LH-20 column, or by preparative TLC (thin layer chromatography) or HPLC (high performance liquid chromatography), etc. Each method gave satisfactory results, but HPLC gave the best...
Aniline was the main product under solvent-free condition with a high selectivity above 98% (by gas chromatography, GC). The conversion of nitrobenzene was approximately proportional to reaction time, indicting the reaction might follow zero-order kinetics with respect to nitrobenzene under fixed H2 ...

活性蛋白整体方案 Active Protein Solutions 离子交换色谱的原理介绍和实际操作 离子交换色谱是蛋白纯化技术中常用的一种纯化方法,其原理是指 被分离物质所带的电荷可与离子交换剂所带的相反电荷结合,这种 带电分子与固定相之间的结合作用是可逆的,在改变 pH 或者用逐 渐增加离子强度的缓冲液洗脱时,离子交换剂上结合...
In the present investigation the carbinol extract of Aegle marmelos leaves analysis Gas chromatography- Mass spectrometry that result revealed the different chemical component such as 3-O-methyl-d-glucose, Behenic acid, 2-(4-Isobutylphenyl)propanoic acid, BF5TT and 3-Buten-2-one, 4-(4-hydroxy...
europaeus Analysis of the methanolic extract of the subaerial parts of L. europaeus using high performance liquid chromatography (HPLC) revealed the presence of one major compound with UV max at 290 and 330 nm (Figure 2). Isolation of this major compound by Sephadex® LH 20 column ...
They fabricated carbon resistors on cantilever beams made of chromatography paper. Although they named their device a MEMS sensor, its size (~cm) is quite large compared to the ones made from Si which are micro-scale. An extension of this work was presented by Ren et al. [8]. They ...
Micellar electrokinetic chromatographyOver the last couple of decades, researchers have developed diverse chiral separation methods emerged from a few chiral separation principles. This review article is primarily focused on the application of chiral ligand-exchange (CLE) principle in capillary ...
