WebColumn plate count is a measure of resolution, or the separating efficiency. The column manufacturer provides the initial plate count. This value changes over time, and ASTRA can calculate the new value to help you track the efficiency of your column. The more plates, N, and the smaller the plate height, the better the resolving power. WebFilter the mixture to extract the liquid. 6. Use a capillary tube to extract some of filtrate. 7.
