Please note: SGE has made the decision to discontinue the manufacture of the Air Sharp™, effective December 31, 2011. Technical support, and the replacement parts below, will be available until December 31, 2017.
The AirSharp™ is a peak-focussing GC accessory that uses ambient temperature compressed air as a coolant to cool a very small area of the capillary column rather than the standard liquid carbon dioxide (CO2) or liquid nitrogen (N2) that are used in many of the currently available cold traps.
Designed to focus individual high boiling, late eluting peaks just prior to the compounds entering the detector, the AirSharp increases the signal-to-noise ratio and sensitivity of individual peaks thereby lowering detection limits and making low-level analyses easier.
The risk of contamination onto the capillary column resulting from excess large volume injections, is also decreased.
