Abstract

Miniaturization and optimization of the solvent delivery system, mixing device, and detection system for gradient elution at few μl/min is the most important objective of instrumental development in microHPLC using packed capillary columns. Instrumental solutions and evaluation of the performence of a dedicated system for automatic gradient elution with packed capillary columns are reported. Retention time precision shown buy the system results in an RSD of 0.20–0.52% for a PAH model mixture eluted under gradient conditions at few μl/min. Compositional accuracy of gradient profiles is also demonstrated.

When packed capillary columns are coupled to electrospray mass spectrometry, care must be taken to reduce the dead volumes of the detector connections. In this work, the coupling between the column and the detector was made with a 20-m i.d. fused silica capillary which was inserted in the electrospr
