Supplier: MACHEREY-NAGEL

Special GC phase for the analysis of volatile halogenated hydrocarbons.

Supplier: MACHEREY-NAGEL

Special GC phase for the analysis of diethylene glycol.

Supplier: CHIRAL TECHNOLOGIES

These columns allow chromatographers to employ essentially any organic solvent as mobile phase to develop methods for the most challenging separations. These columns are available in a variety of particle sizes and offer great speed and column resolving power. Columns packed with 3 µm CSPs offer high speed separations and a reduction in analysis time and cost per sample. Columns, packed with 3 µm particles, may be used in conventional HPLC units without significant loss in performance, even with the smaller column dimensions.
