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.
Benefits of Derivatization:
- 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 analysis.
- Increased instrument and lab productivity – fewer reinjections or repeats due to peak tailing – high confidence in analyte identification and quantitation – easy to perform – inert by-products of derivatization will not degrade capillary column performance.
