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 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.
The metal capillary columns supplied by SRI are typically wound on a 3.5" coil form and are available in a variety of stationary phases.
8600-WBC1 15-meter MXT type 0.53mm capillary column—this is a good column length for simple mixtures, fast screening, or compounds with high molecular weight.
