Capillary columns for GC
Polysiloxane phase with autoselectivity · USP G49
Medium polar without CN groups
Analytes determine the polarity of the phase
Autoselectivity resulting in a polarity range from approximately the nonpolar OPTIMA® 5 to the midpolar OPTIMA® 1701
Unique from MN, no similar phase
Ideal for MSD and PND detectors

For columns with 0.1–0.32 mm ID the max. temperature for isothermal operation is 340 °C,
the max. temperature for short isotherms in a temperature program is 360 °C;
for 0.53 mm ID columns the max. temperatures are 320 and 340 °C, respectively

In addition to this standard program we will be happy to supply columns custom-made to your specifications.
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., 726441.30E)
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.
