GC Columns

GC columns are the capillary columns at the heart of every gas chromatography separation, chosen by stationary phase, internal diameter, film thickness and length. Environmental, food, petrochemical and pharmaceutical laboratories depend on GC columns for volatile and semi-volatile analysis.

The 609 listings are all Macherey-Nagel. Among them are PERMABOND CW 20 M capillary columns in 0.25 mm internal diameter with a 0.25 µm film, in 10 m, 25 m, 30 m and 50 m lengths, with many further phases and dimensions in the range.

Select the phase for your analyte polarity, a narrower bore and thinner film for resolution and speed, and a longer column when closely eluting peaks need separating. Lancetech Limited supplies Macherey-Nagel GC columns to UK laboratories and will quote on method-specific requirements.
