TRB-1MS
100% Dimethyl polysiloxane, bonded and crosslinked phase.
• These columns, with a selectivity identical toTRB-1, fulfil column bleed specifications that make them compatible with analysis of trace components with GC/MS. Therefore, the standard column of 30m x 0.25mm x 0.25μm has a guaranteed maximum bleed of 4 pA at 325 °C.
• Great chemical inertness towards active constituents and excellent thermal stability.
• Improved signal/noise ratio, which enables greater sensitivity to be obtained with the MS, ECD, NPD, SCD, etc. detectors and provides greater precision in quantitative analysis at trace levels.
• Less column bleed means less detectors contamination and greater speed in conditioning columns.
