Each column is individually tested and supplied with test certificate and test chromatogram, but without fittings or ferrules. Columns have fused ends or are sealed with septa, to protect them from atmospheric oxygen.
For checking the column performance the respective test mixture can be obtained separately.
On request, all columns can be supplied on a 5 inch (13 cm) cage for the Agilent GC 6850. To order, please add an E at the end of the REF number (e.g., 725850.30E)
To prolong column life, even at highly contaminated or matrix-containing samples, MN offers the option to add an integrated guard column. All capillary columns are available with a 10 m guard column with respective deactivation. To order, please add V1 at the end of the REF number. Guard column combinations with other lengths, IDs or different deactivation are available on request.
