ABSTRACT:
An apparatus for measuring components in a liquid medium, in particular parenteral nutrients, within a flexible transparent bag. A spacer is utilized to fix or determine the optical path across the bag chamber and includes a passage for electromagnetic radiation of selected wavelengths. The source of electromagnetic radiation is capable of sending radiation into the bag chamber and to detector means which analyzes the radiation passed through or reflected from the components in the bag chamber.
