ATLANTA (October. 6, 2011) – Thermo Fisher Scientific Inc., the world leader in serving science, today introduced the Thermo Scientific TraceGOLD GC Column with SafeGuard, which combines an analytical gas chromatography (GC) column with a built-in guard column. The SafeGuard feature extends the life of the analytical column without compromising its chromatographic performance. Available in a range of guard column lengths and analytical column specifications, TraceGOLD™ GC Columns with SafeGuard are suitable for use in a broad spectrum of applications that necessitate the injection of involatile sample matrix, particularly in environmental, forensic, food safety and petrochemical analyses.
To prolong their life, GC columns are routinely cut to remove contaminant deposits. With conventional columns, however, this practice reduces the separation accuracy, peak resolution and column quality over time. With the TraceGOLD GC Column with SafeGuard, on the other hand, users can cut columns during routine maintenance with no impact on the chromatography performance of the analytical column.
