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. WebColumn packing Historically, column packing has been a manual process (using flow or pack in place methodology). Some major challenges with manual column packing are varying packing success rate and bed instability. Also, modern high-flow resins were found to be less compatible with the hardware design of traditional columns. After evaluating the
