SRI can supply and install just about any type of column. We like the metal capillary columns because
they are unbreakable, can be coiled to a smaller diameter, yet cost and perform the same as fused silica
columns—which can anddobreak.
For some applications such as gases, freons, water andothers, packed columns arepreferred.
The column oven on the
SRI Model 8610C GC can
accommodate a single 7 inch
columncageormultiplecolumns
wound on a smaller form. The
column oven on the Model 310
GC can accommodate a single
4 inch column cage or multiple
columns on a smaller coil.
