Development of a fritless packed column for capillary electrochromatography–mass spectrometry

Enantiomer separation by capillary electrochromatography using fritless packed columns.

This review summarizes recent developments in the field of enantiomer separation by capillary electrochromatography using fritless packed columns. Various enantiomers have been separated by employing fritless packed columns prepared in a fused silica capillary either by the immobilization of chiral packing materials by sintering or sol-gel technology or by in situ polymerization of a mixture co...

Fritless packed columns with great potential for use in capillary Electrochromatography

T he past several years have seen a significant resurgence of interest in cap i l l a ry electro ch ro m at ography(CEC), a hybrid technique that combines the high efficiency owing to the flow characteristics related to electroosmosis with the selectivity of high performance liquid chromatography(HPLC). In CEC, separations are generally carried out using fused silica capillaries packed with HPL...

Characteristics of TGPGC on short micro packed capillary column.

Column switching analysis with packed-capillary columns in gas chromatography.

By introducing sequentially connected two packed-capillary columns, a wide range of volatile compounds were successfully separated in gas chromatography. The hyphenation of two packed-capillary columns of 1.0 mm i.d. was accomplished using a conventional 6-port valve, where the temperature of each column was individually controlled in the respective column ovens. These columns were prepared w...

Integration of monolithic frit into the particulate capillary (IMFPC) column in shotgun proteome analysis.

Capillary column plays an important role in nano-flow liquid chromatography coupled with tandem mass spectrometry for dealing with the high dynamic range and complexity of protein samples in shotgun proteome analysis. In this study, the integrated monolithic frit into the particulate capillary (IMFPC) column was prepared. By comparing the prepared IMFPC column with conventionally fritless capil...
