SELECTRA-SIL® Derivatizing Reagents SELECTRA-SIL® is an extensive line of derivatizing reagents manufactured by UCT at its facility in Bristol, PA. Our reagents are designed to increase molecular weight, lower boiling points, and create a more specific ion for compounds intended for gas chromatography and GC/MS. SELECTRA-SIL® Derivatizing Reagents Benefits: Improved chromatographic resolution - increased volatility - reduced intermolecular hydrogen bonding - separation of structurally similar compounds. Improved mass spectral characteristics - higher mass fragments - greater signal to noise ratio - more unique masses- increased abundance/sensitivity of molecular ions. Improved thermal stability of some compounds - reduced thermal degradation - higher temperature to speed analysi...Read more
