Abstract
A sampling unit is fluidically coupled to a source. The sampling unit is configured for receiving a fluidic sample from the source and chromatographically separating the received fluidic sample. The sampling unit is operated to introduce a test sample into the source. At least a portion of the introduced test sample from the source is received into the sampling unit, and the received portion of the test sample is chromatographically separated in the sampling unit.
Claims20
A method of testing a sampling unit configured for chromatography, the method comprising:
- providing the sampling unit fluidically coupled to a source, wherein the sampling unit is configured for receiving a fluidic sample from the source and chromatographically separating the received fluidic sample, and the sampling unit comprises a valve;
- operating the sampling unit to introduce a test sample into the source;
- receiving at least a portion of the introduced test sample from the source into the sampling unit by branching off the portion of the introduced test sample from the source, at a fluidic coupling point of the valve, into the sampling unit;
- and
- chromatographically separating the received portion of the test sample in the sampling unit.
A sampling unit fluidically coupled to a source, wherein the sampling unit is configured for receiving a fluidic sample from the source and chromatographically separating the received fluidic sample, the sampling unit comprising:
- a fluid drive configured to drive a mobile phase;
- a metering unit configured to meter fluidic volumes;
- a separation unit configured to provide a chromatographic separation;
- a valve configured to fluidically couple with the source;
- and
- a control unit configured to perform the following:
- operating the metering unit to introduce a test sample into the source;
- operating the metering unit to draw in at least a portion of the introduced test sample from the source into the sampling unit by branching off the portion of the introduced test sample from the source, at a fluidic coupling point of the valve, into the sampling unit;
- and
- operating the metering unit to eject the drawn in portion of the test sample into the mobile phase for chromatographically separating the drawn in portion of the test sample by the separation unit.
