Packed and Capillary Columns
- 15, 30, and 60-meter 0.53 mm metal wide-bore capillary columns wound on a 3.5″ coil
- 1/8″ and 1/4″ O.D. packed columns
SRI can supply and install just about any type of column. We like the metal capillary columns because they are unbreakable, and can be coiled to a smaller diameter, yet cost and perform the same as fused silica columns, which can and do break.
For some applications such as gases, freons, water, and others, packed columns are preferred.
The column oven on the SRI model 8610C can accommodate a single 7″ column cage or multiple columns wound on a smaller form. The column oven on the model 310, 410, and the duals on the 8610D, can accommodate a single 4″ column cage or multiple columns wound on a smaller coil.
