Columns low pressure chromatography

Other chromatographic techniques that have been applied to the tetracyclines, including CTC, involve low pressure column chromatography. Ascione et al. (64) developed a semiautomated system whereby sample solutions are automatically injected onto a column of diatomaceous earth mixed with... [Pg.127]

Liquid chromatography was, is and always will be an essential technique for the purification, separation and isolation of amylodextrins. Liquid chromatography is herein classified into low pressure column chromatography and high pressure liquid chromatography (HPLC). The basic distinction between the two is the size of the column packing with 25 urn as the typical division. [Pg.146]

Low pressure column chromatography is characterized by the use of compressible column packings 025 urn) which require the use of low pumping pressures, e.g. hydrostatic pressure or peristaltic pumps, and extended analysis times in the region of 2-18 hours. Detection is frequently performed using automated assay systems, e.g. an L-cysteine sulphuric acid system, or by manual assay following collection of eluant fractions (1). [Pg.146]
