General description
Rejuv-8™ is a commercially available resilylating mixture of N,O-bis(trimethylsilyl)acetamide, hexamethyldisilazane and 1-(trimethylsilyl)imidazole.
Application
Rejuv-8™ was used as resilylating reagent during:
- postcoating treatment performed for the GC column in fast separation of organophosphonate and organosulfur compounds.
- pre-reduction and cryotrapping for speciation analysis of pentavalent arsenicals by thioglycolic acid using selective hydride generation-cryotrapping-atomic absorption spectrometry.
- studying GC models for separation optimization in pressure-tunable tandem capillary columns using new capillary column interface.

This article demonstrates how to prepare microfabricated columns (microcolumns) for organophosphonate and organosulfur compound separation that rival the performance of commercial capillary columns. Approximately 16,500 theoretical plates were generated with a 3 m long OV-5-coated microcolumn with a 0.25 microm
