Blood analysis system

The blood analysis system (360) according to 14, wherein each of the correction units (130, 132, 170-1, 170-2, 170-3) comprises:

• a seventh cell (340) coupled to a channel (300) to receive plasma with the capturing molecules and with molecules and/or ions that are to be corrected and having a seventh SPM (344) of a specific molecular weight cut-off that allows molecules of a molecular weight equal to or less than the specific molecular weight cut-off to pass through;
• and
• an eighth cell (342) coupled to the channel (300) to receive plasma with the capturing molecules and with molecules and/or ions that are to be corrected and having an eighth SPM (346), the eighth SPM (346) being the same as the seventh SPM (344),
• wherein one of the seventh cell (340) and the eighth cell (342) is operated to separate the molecules and/or ions and/or the capturing molecules and the other of the seventh cell (340) and the eighth cell (342) is operated for declogging,
• wherein the capturing molecules are removed from one of the seventh cell (340) and eighth cell (342) and discarded,
• wherein chambers on a retentate side of the seventh and eighth SPMs (344, 346) of each of the seventh cell (340) and the eighth cell (342):
• are coupled to a channel (320, 318) to receive capturing molecules having a concentration depending on an amount of excess molecules and/or ions that are to be captured and removed from the plasma via the chambers on the retentate side, and
• are coupled to a respective concentration unit (354, 358) and a respective detection unit (356, 360) to concentrate and detect, respectively, un-captured retentate molecules and/or ions during declogging of the seventh cell (340) or the eighth cell (342) or to correct a concentration of the un-captured retentate molecules and/or ions based on the detection,
• wherein chambers on a filtrate side of the seventh and eighth SPMs (344, 346) of each of the seventh cell (340) and the eighth cell (342) are coupled to a respective concentration unit (346, 350) and a respective holding unit (348, 352) to concentrate and hold, respectively, filtrate molecules and/or ions before passing the filtrate molecules and/or ions towards the collecting channel (180).
