New State-of-the-Art in Gas Chromatography Columns

(Waltham, MA, USA), a developer of analytic instrumentation.

The value of ultra-low bleed columns is readily apparent to investigators who rely on GC/MS technology. Low bleed columns are essential for the integrity of analytic results. The amplitude of baseline noise associated with column bleed is indicative of stationary phase stability. A low bleed, stable column produces consistent results, and the low baseline noise enables improved limits of detection with enhanced resolution of low-level analytes. Column bleed also contributes to contamination of the MS; minimizing column bleed extends the interval between scheduled maintenance, leading to higher productivity.

Run-to-run reproducibility is essential for all analytic laboratories. An advantage of low column bleed columns is the greater reproducibility of the stationary phase over a period leading to greater run-to-run reproducibility.

Thermo Scientific maintains that the TraceGOLD GC columns assure the highest levels of reproducibility, ensuring that the best peak shapes and sensitivity are obtained every time.
