High performance liquid chromatography microbore HPLC

Capillary column This term refers to a chromatographic column of small diameter and is used in both gas and high performance liquid chromatography. In HPLC, the term is usually apphed to columns with internal diameters of between 0.1 and 2 mm. The term microbore column is often used synonymously to describe these columns but is more correctly applied to columns with internal diameters of 1 or 2 mm. 

In conventional high-performance liquid chromatography (HPLC), columns are usually of 10-25 cm length and 2—4 mm i.d. Recently, capillary HPLC columns have become available in the market. The terminology, abbreviations, and definitions have not yet been standardized. In the literature, we can find microbore, micro-LC, semimicro-LC,...
