Technologies Set to Blaze at PITTCON 2005
Florida (February 27, 2005) – Temperature Programmed Liquid Chromatography
(TPLC) specialist, Selerity Technologies Inc unveils a new silica-based
stationary phase that can withstand temperatures up to 200ºC
for the first time on booth #2739 at PITTCON 2005,
Orlando, Florida, February 27 – March 4 . The new Blaze 200 ™ column
opens up a range of new opportunities for the separations scientist
looking to take advantage of better results and peak shapes. This
novel advancement in column technology means that most barriers
preventing the use of extreme temperature in HPLC can now be overcome.
there are a variety of stationary phases such as polymeric and graphitic
carbon materials that can be used at elevated temperatures, most
HPLC chemists prefer the selectivity and higher efficiencies of
silica-based columns. Increasing temperature can drastically limit
the column lifetime when the bonded phase is based on traditional
chemistries. Most silica-based HPLC columns can only be used to
temperatures up to 60°C and a pH range of 3-8. Such columns
have a propensity to degrade as water attacks the underlying support
new Blaze 200 ™ column overcomes these obstacles. It consists of
a new polydentate silica phase that is stable at extreme temperatures,
with added pH stability. The development of a new polycarbosilane
bonding chemistry that is hydrolytically stable against breakdown
in aqueous environments facilitates such analyses. It integrates
multiple point attachments to the silica with a high degree of cross-linking.
This combination creates a highly protective barrier over the silica
backbone, protecting it from hydrolytic attack.
offers traditional C18 selectivity, while providing enhanced temperature
stability for use up to 200°C and pH conditions as high as 12.
Columns based on this chemistry are useful for both isothermal and
programmed separations over wide ranges of temperature.
