Microbore columns in liquid chromatography
Microbore columns were investigated for their application to High Performance Liquid Chromatography. Microbore columns consist of stainless steel tubing, 1/16¹¹ OD x 1mm ID, packed with silica gel or other suitable material. These columns were evaluated in terms of extra-column variance effects, …

Microbore HPLC methodology and temperature programmed microbore HPLC
Small diameter LC columns provide rapid thermal equilibration and are ideal candidates for temperature programmed LC. Special instrumentation requirements are presented and details of column assembly are given to permit the preparation of highly efficient, stable microbore columns. Three LC …

Infrared spectrometry as a high performance liquid chromatographic detector with application to solvent refined coal products
… transparent solvent is demonstrated. Work with microbore (1 mm i.d.) columns coupled with on-line flow cell detection is presented. Modification of the flow cell design for microbore compatability is shown as well as the benefits of microbore columns for fiow cell FTIR. Detection limits as …

A study of column switching liquid chromatography in drug analysis.
… volumes used and the varied longevity of the columns. The advantages and disadvantages of microbore columns and their use in column switching systems are discussed. A systematic study was carried out with 4.6, 2 and 1 mm analytical columns and varied precolumn dimensions. The mass sensitivity …

Feasibility of analysis of polar compounds by high performance liquid chromatography with Fourier transform infrared spectroscopic detection
… aid in identification. Both analytical size and microbore normal phase columns were employed. Such experimental considerations as column overload, injected minimum detectable quantities, the use of analytical vs. microbore columns and flow cell pathlength were examined. The developed HPLC-FTIR …
