High-speed GC/MS using narrow-bore columns and ion trap detection

HPLC separations with micro-bore columns using high-temperature water and flame ionization detection.

Previous work demonstrates that a flame ionization detector (FID) may be used as a detector for high-temperature water separation. However, the relatively high flow rate of the eluent required by standard high-performance liquid chromatography columns causes instability of the FID. In this work, micro-bore columns are packed with poly(styrene-divinylbenzene) (PRP-1) or Daiso gel octadecylsilane...

Rapid high performance liquid chromatography method development with high prediction accuracy, using 5cm long narrow bore columns packed with sub-2microm particles and Design Space computer modeling.

Many different strategies of reversed phase high performance liquid chromatographic (RP-HPLC) method development are used today. This paper describes a strategy for the systematic development of ultrahigh-pressure liquid chromatographic (UHPLC or UPLC) methods using 5cmx2.1mm columns packed with sub-2microm particles and computer simulation (DryLab((R)) package). Data for the accuracy of comput...

Application of Narrow-Bore HPLC Columns in Rapid Determination of Sildenafil Citrate in Its Pharmaceutical Dosage Forms

     A special type of silica-based columns has been recently introduced into the market which is called narrow-bore columns. They have lower internal volume than the standard high-performance liquid chromatography (HPLC) columns and thus reduce the solvent consumption by almost 80%.    A simple, accurate and environmentally friendly reversed phase- HPLC (RP-HPLC method) which could be used in ...
