GC Column TRB-5, 50 m x 0.25 mm x 1 µm

95% Dimethyl- 5% diphenylpolysiloxane, bonded and crosslinked phase.
It is the most versatile and universal stationary phase in the gas chromatography analysis fi eld
The low percentage of phenyl in the polymer structure gives it a characteristic affi nity towards the compounds with aromatic rings. This phase, the most popular one, due to its great thermal stability and chemical inertness is the stationary phase of choice for any type of analysis
It allows the analysis of acidic and basic compounds
It is ideal for the analysis in the environmental fi eld. Analysis of dioxines, PCB´s, PCT´s, polyaromatic compounds, phenols, herbicides, organochlorinated and organophosphorus pesticides, aromatic hydrocarbons, solvents, drugs, oils, etc...
