GC Column TRB-1MS, 15 m x 0.25 mm x 1 µm

100% Dimethylpolysiloxane
These columns gives identical selectivity to the TRB-1, fulfil column bleed specifications that make them compatible with analysis of trace components with GC/MS. Therefore, the standard column of 30 m x 0.25 mm x 0.25 μm has a guaranteed maximum bleed of 4 pA at 320 °C
Great chemical inertness towards active compounds and excellent thermal stability
Improved signal/noise ratio, which enables greater sensitivity with MS, ECD, NPD, SCD, etc. detectors and provides greater precision in quantitative analysis at trace levels.
Less column bleed means less detectors contamination and faster column conditioning
