Accelerated Purge and Trap Technology: A Study On Increased Speed and Improved Chromatography

Julie Kancler

Since the 1970's, Tekmar has introduced many leading products in the trace volatile analysis market. Tekmar-Dohrmann now introduces the Velocity XPT™ Accelerated Purge and Trap System. Velocity XPT offers increased speed, extremely low carryover and significantly improved water control, creating a dramatically more productive instrument that provides superior data quality.

To achieve greater analytical efficiency, several new innovations have been integrated into the Velocity XPT. This paper discusses the Forward Focusing Chamber™ and its ability to tighten sample bands, improving peak shape and response of gaseous compounds, as well as water control improvements using DryFlow™ and electronic flow control. The benefits of significantly improved chromatography combined with dramatic increases in speed, form an exciting new advance in purge and trap instrumentation...
