Dual liquid chromatography Dual liquid chromatography is a multichannel HPLC method using two separate flow paths in a single system to run two analyses simultaneously. These HPLC systems have two pumps with two independent solvent paths, two dosing units inside the autosampler, and...

HPLC has evolved since the first introduction of instruments, columns, and development of methods and applications. This evolution has culminated in ultra-high performance liquid chromatography (UHPLC) nowadays. However, one may question whether the current separation performance of UHPLC columns has re...
虽然CRD无法治愈,但患者可以使用维持性药物(例如β-2肾上腺素受体激动剂(BA))来帮助缓解症状3。 BA可以进一步分为三类:短效B2激动剂(SABA)、长效B2激动剂(LABA)和超长效B2激动剂(ULABA)。鉴于CRD的患病率较高,舒喘宁等BA类药物多年来一直位居处方药排行榜前10位也就不足为奇了4。
The basics of HPLC is explained using simple words. 1. History of Chromatography The history of chromatography dates back to the beginning of the 20th century. In 1903, a Russian scientist M. Tswett used a glass tube filled with chalk powder (calcium carbonate) and placed a pigment (...
Selection of solvents for use as a mobile phase in HPLC analysis is a key component of method development. It is not possible to hava a universal solvent which will meet all applications and more than often a combination of solvents is decided based on the analysis requirements. Selection of ...
