Alternatively, you can use 10·32 (1/16“) fingertight fittings that are available from chromatography supply houses. In either case, make sure to insert the capillary tubing fully into the column end fitting before setting the ferrule by tightening the nut. Repeat to make the connec- tions at the other end of the 1/16“...
If the column inlet fitting appears dry, we recommend that you first disconnect the bottom cap and hook up the column exit to the injector. Then slowly start the flow in this reversed flow direction until a few drops of mobile phase exit from the column.
Efficiency (N) N = 5.54 (V = elution volume at the peak maximum ½ h = width of peak at half height Asymmetry factor (AF) AF = b/a AF is measured at 10% of the peak height. Resolution (R = elution volume of first = 2(V and second...

For example, a low pH salt solution will remove basic proteins. Organics will remove hydrophobic proteins. Chaotropic agents will remove strongly adsorbed materials (e.g., via hydrogen bonding). For columns or column types not listed below, please contact Tosoh Bioscience Technical Service for the appropriate solutions.

Cleaning solutions Generally, 3-5 column volumes (CV) of cleaning solution is sufficient. Rinse well with 3-5 CV of distilled, deionized water between each solution. Only use chaotropic agents when neutral salt or organic has not improved performance characteristics. SW and SW , UP-SW, Super SW 1.
As a last resort, buffered solutions of SDS (0.1%), urea (8 M) or guanidine (6 M) can be used to clean the column. We only recommend this method if all other methods fail. Storage Consult the OCS sheet for the recommended storage solvent and storage tem- perature or temperature range for this column.

If not, clean and/or replace the end fitting (available from Tosoh Bioscience) as described below. To clean or replace the end fitting, use a vise to carefully remove the old fitting from the top of the column, making sure not to disrupt the gel packing at the col- umn top.
If a product is authorized for return for reasons other than Tosoh Bioscience’s error or because of a product defect, there will be a restocking charge of 25 Euro or 10% of the list price, whichever is greater.
