The present invention pertains to method for discriminating bulk liquid from foam and/or residuals of said bulk liquid of a sample contained in a sample vessel, comprising the following steps: providing a probe having an electric capacitance; moving said probe into said sample; repeatedly performing a pair of consecutive steps of charging and at least partially discharging said probe to generate a discharging current; measuring a quantity indicative of said discharging current for each pair of consecutive steps of charging and at least partially discharging said probe; analyzing said quantity in a manner to determine an electric resistance (R mess ) of said sample via said probe; discriminating said bulk liquid from said foam and/or said residuals of said bulk liquid based on a change of said electric resistance (R mess ) of said sample occuring when said probe contacts said bulk liquid. It further pertains to an automated system for discriminating bulk liquid from foam and/or residuals of said bulk liquid of a sample contained in a sample vessel. |
