Abstract:
1. A method for controlling the application of a coating of a liquid sample on a substrate based on the surface-coating characteristics of said liquid sample for said substrate, said method comprising the steps of (a) advancing a volume of liquid sample completely through an open-ended tubular member, said tubular member having coating retention characteristics at least similar to those of said substrate; (b) determining the amount of a residue of the liquid sample remaining on the interior walls of said tubular member after such volume of the liquid sample has been advanced completely through the tubular member; (c) determining from said amount of residue the surface-coating characteristics of the liquid sample specific for the coating-retention characteristics of said tubular member and said substrate; and (d) controlling subsequent coating of said liquid sample on the substrate based on the determined surface-coating characteristics of said liquid sample for said substrate.
