摘要： The present technology generally relates to a porous medium parameter measurement device. The porous medium parameter measurement device comprises: a liquid permeable portion comprising a fluid permeable component and a polymer swellable solution; and comprises a gas permeable portion comprising a gas permeable component. The liquid permeable portion is in operative communication with the gas permeable portion through the gas permeable component; and the gas permeable component acts to purge gases from the liquid permeable component and the polymer swellable solution.

摘要： A method for determining physical parameters of a liquid (22) to be aspirated and/or dispensed by a laboratory automation device (10) comprises: pickup of a pipette (14) with the laboratory automation device (10); lowering the pipette (14) into a sample container (18) with the laboratory automation device (10), the sample container (18) containing the liquid (22); aspirating and dispensing air and liquid (22) with the laboratory automation device (10) in such a way, that a liquid level in the pipette (14) solely rises in a first step and solely lowers in a second step, such that an interior surface of the pipette (14) is wetted with liquid solely one time; and during aspirating and dispensing air and liquid (22), measuring a pressure curve (40) in the pipette (14) and determining the physical parameters from the pressure curve (40), the physical parameters comprising at least one of a surface tension, a wetting angle and a viscosity.

摘要： A method for determining physical parameters of an unknown liquid (22) to be aspirated and/or dispensed by a laboratory automation device (10) comprises: determining physical parameters of the pipette (14), the physical parameters including geometric parameters of the pipette (14), which at least include a tip radius of an orifice of the pipette (15); aspirating and/or dispensing the unknown liquid (22) with a pipette (14) of the laboratory automation device and measuring a measured pressure curve (40) in the pipette (14) during aspirating and/or dispensing; determining the physical parameters of the unknown liquid (22) by minimizing an objective function depending on a difference (44) between a simulated pressure curve and the measured pressure curve, wherein the simulated pressure curve (42) simulates a pressure in the pipette (14) during aspirating and/or dispensing and is calculated based on a physical model of the laboratory automation device (10) including the physical parameters of the pipette (14), wherein the physical parameters of the unknown liquid (22) are varied to minimize the objective function.

摘要： An apparatus includes a probe (108) configured to provide at least a portion of capacitance of an inductance-capacitance (LC) circuit (104) of a detection circuit, the capacitance of the LC circuit being dependent on a distance between the probe (108) and a surface (122) of a liquid (118) in a biochemical analysis system (100). The apparatus includes a movement mechanism (110) configured to move the probe (108). The apparatus includes circuitry configured to perform operations that include causing the movement mechanism (11) to move the probe (108) with respect to the liquid (118); measuring one or more characteristics of an output signal of the detection circuit (104), the one or more characteristics being dependent on the capacitance of the LC circuit; and detecting, based on the one or more characteristics of the output signal, a contact between the probe (108) and the surface (122) of the liquid (118).
