Abstract: A method of controlling a sample separation apparatus, for separating a fluidic sample using a mobile phase provided from at least one mobile phase container, includes determining a weight and volume reduction behavior according to which weight and volume of mobile phase in a mobile phase container are reduced during conveying mobile phase from the mobile phase container in the sample separation apparatus, and determining a tare weight of the mobile phase container based on a gross weight information, a volume information, and the determined weight and volume reduction behavior. The gross weight information is indicative of an initial gross weight of the mobile phase container including its mobile phase, and the volume information is indicative of an initial mobile phase volume in the mobile phase container.

Abstract: In a sample separation apparatus for separating a fluidic sample using a mobile phase provided from at least one mobile phase container, a method of determining a density of the mobile phase includes determining a weight and volume reduction behavior according to which weight and volume of mobile phase in a mobile phase container are reduced during conveying mobile phase from the mobile phase container in the sample separation apparatus. The density of the mobile phase is determined based on the determined weight and volume reduction behavior.

Abstract: In a sample separation apparatus for separating a fluidic sample, a mobile phase container is identified by determining a weight and volume characteristic of the mobile phase container, and identifying the mobile phase container based on a comparison of the determined weight and volume characteristic of the mobile phase container with a pre-known reference weight and volume characteristic of one or more reference mobile phase containers with pre-known identity. A mobile phase is identified by determining a weight and volume reduction behavior according to which weight and volume of mobile phase in a mobile phase container are reduced during conveying mobile phase from the mobile phase container in the sample separation apparatus, and identifying the mobile phase based on a comparison of the determined weight and volume reduction behavior with pre-known reference weight and volume reduction behavior of one or more reference mobile phase materials with pre-known identity.

Abstract: A mobile phase supply device, for supplying a mobile phase for a sample separation apparatus for separating a fluidic sample, includes a fluidically normally closed cap device configured to be mounted on a mobile phase container containing a mobile phase, and a fluidically normally closed port device configured for being mechanically connected with the cap device in such a way that, upon establishing a mechanical connection between the port device and the cap device, both the port device and the cap device are converted into a fluidically opened configuration.
