In a method for processing successive fluidic sample portions provided by a sample source, sample reception volumes are filled successively temporarily with at least a respective one of the sample sections, and the sample sections are emptied successively out of the sample reception volumes in such a way, that, while emptying, it is avoided to bring two respective ones of the sample sections, which have not left the sample source directly adjacent to one another, in contact with one another.

Temporary storage of sample portions for artefact-preventing fluid processing

An apparatus for deriving an operation mode from a first fluidic device to a second fluidic device, wherein the first fluidic device has a first target operation mode representing a desired behavior of the first fluidic device and has a first real operation mode representing the actual behavior of the first fluidic device, wherein the second fluidic device has a second target operation mode representing a desired behavior of the second fluidic device and has a second real operation mode representing the actual behavior of the second fluidic device, the apparatus comprising a first determining unit configured for determining the first real operation mode based on the first target operation mode and based on a preknown parameterization of the first fluidic device, and a second determining unit configured for determining the second target operation mode based on the determined first real operation mode and based on a preknown parameterization of the second fluidic device.

Method transfer between fluidic devices considering deviations from ideal behavior

A dilution apparatus () for diluting a fluidic sample in accordance with a specifiable dilution ratio, wherein the dilution apparatus () comprises a dilution fluid supply device () configured for supplying a dilution fluid at a first quantity per time, a transport fluid supply device () configured for supplying a transport fluid at a second quantity per time, a first fluid accommodation unit () configured for accommodating a first fluid volume, a second fluid accommodation unit () configured for accommodating a second fluid volume, and a control device () configured for controlling the flow of the dilution fluid, the transport fluid and the fluidic sample so that in a first operation mode, the fluidic sample, being accommodated in the first fluid accommodation unit (), is forced to flow to the second fluid accommodation unit () while being diluted by being mixed with dilution fluid, and in a second operation mode, the mixture of dilution fluid and fluidic sample, being accommodated in the second fluid accommodation unit (), is forced to flow from the second fluid accommodation unit () to the first fluid accommodation unit () while being further diluted by being mixed with further dilution fluid.

Sample dilution to specifiable dilution ratio

An apparatus () for deriving an operation mode from a first fluidic device to a second fluidic device, wherein the first fluidic device has a first target operation mode () representing a desired behavior of the first fluidic device and has a first real operation mode () representing the actual behavior of the first fluidic device, wherein the second fluidic device has a second target operation mode () representing a desired behavior of the second fluidic device and has a second real operation mode () representing the actual behavior of the second fluidic device, the apparatus () comprising a first determining unit () adapted for determining the first real operation mode () based on the first target operation mode () and based on a preknown parameterization () of the first fluidic device, and a second determining unit () adapted for determining the second target operation mode () based on the determined first real operation mode () and based on a preknown parameterization () of the second fluidic device.

A method for controlling operation of a pump unit, where the pump unit includes a primary piston pump having a primary piston and a secondary piston pump having a secondary piston. The primary piston pump is fluidically connected with the secondary piston pump. The primary piston pump includes an inlet valve and an outlet valve, and the pump unit operates periodically according to a pump cycle. The method includes determining a fluid pressure of fluid dispensed by the pump unit, and performing a closed loop control of a position of the primary piston in dependence on the fluid pressure of the fluid dispensed by the pump unit during a first time interval of the pump cycle.

Primary piston correction during transfer

An apparatus for determining an operation mode of a device, wherein the device is capable of adjusting a physical condition at a source position to correspondingly influence a physical condition at a destination position, the apparatus comprising a determining unit adapted for determining the operation mode by defining a time dependency of the physical condition at the source position so that a target time-dependency of the physical condition is obtained for the destination position, the target time-dependency representing a resultant variation of the physical condition over time.

Configuring a physical condition at a source to obtain a desired physical condition at destination

An apparatus for the recognition of exchangeable parts in an analytical measuring instrument or in an analytical measurement system with several analytical devices, which contain exchangeable parts has identification modules each attached to an exchangeable part, and transmit-receive devices which can receive information signals from an identification module and send information signals to an identification module, and a control device which evaluates the information from an identification module. The control device can cause a message to be displayed on a display device, if the information read out from an identification module does not fulfill certain conditions, for example with regard to the quality of the corresponding part.
