WebColumns most suitable for packing HIC media are listed under the column packing section for each HIC medium (Chapter 3). In most cases the binding capacity of the medium and the amount of sample to be purified will determine the column size required. For a complete listing, refer to the Cytiva life sciences catalog. Column packing and efficiency WebWell-packed columns will have an AS of close to 1. All measurements are made at 10% of the maximum peak height. Purity (using peak area)— sample purity can be estimated directly from the chromatogram by comparing the peak areas for the peak of interest vs. all other peaks in the chromatogram.
