Restek Corporation has formed an alliance with
some of the premiere independent instrument serv-
ice providers in the United States, with a goal of
bringing you the finest chromatography operating
supplies, equipment service, and applications sup-
port available.
We are pleased to introduce a new program that
pays you for using Restek products, by reducing
your costs for quality instrument service: STAR
Service Rewards. Similar to our popular Restek
Wizard Dollar program, STAR Service Rewards pays
you one STAR Point for every $50 of Restek prod-
ucts you purchase. Redeem STAR Points with partic-
ipating STAR member service providers for selected
service, equipment, and training products. You get
the finest chromatography operating supplies from
Restek and high quality instrument service from
your preferred service provider. STAR Service
Rewards is one more example of why Restek is the
company chromatographers trust for complete
chromatography support.

furans. The column also shows potential as a
replacement for high-cyano confirmation phases
with poor thermal stability and short lifetimes. We
continue to work to optimize a temperature pro-
gram that resolves all of the toxic congeners, with a
goal of eliminating the need for confirmation.
If you are involved in the analysis of dioxins and
furans, and would like additional information about
Rtx®-Dioxin columns, please contact Frank Dorman
