A photometer for measuring electromagnetic radiation absorption of a sample utilizing a source of the electromagnetic radiation. Electromagnetic radiation is conducted from the source, to a sample sensor or sensors, and is passed through or scattered from, the sample utilizing a sample cell. The electromagnetic radiation is then directed to a detection system which determines absorbance of electromagnetic radiation by the sample at the sample cell. The detection system includes a beam splitter which receives the electromagnetic radiation and outputs first and second beams. A first detector having a first wavelength filter and a second detector having a second wavelength filter receives the two beams from the splitters. One detector may be employed to produce a reference signal. The remaining detector or detectors produce an output signal which is a representation of a characteristic, such as absorbance of the sample. The output signals are compared to a reference signal, and converted into a measurement of absorbance, transmission, reflectance, or turbidity.

Multifunctional photometer apparatus

An apparatus for measuring components in a liquid medium, in particular parenteral nutrients, with 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.

Photometer apparatus

An apparatus for identifying components associated with the liquid in an electrically non-conductive container utilizing a pair of electrodes. The container extends along a particular dimension such that the first electrode is placed adjacent the exterior of the container and at least a second electrode is placed adjacent the exterior of the container in spaced configuration from the first electrode and along the particular dimension of the container. A generated output signal is coupled into the liquid via the first electrode. The output signal is coupled to the second electrode after passing through the liquid component. The output waveforms are analyzed to determine the electrical characteristics of the liquid in order to identify a component within the container.

Apparatus and method for measuring components in a bag

A spectrometer for analyzing a sample of material utilizing a broad band source of electromagnetic radiation and a detector. The spectrometer employs a waveguide possessing an entry and an exit for the electromagnetic radiation emanating from the source. The waveguide further includes a surface between the entry and exit portions which permits interaction between the electromagnetic radiation passing through the wave guide and a sample material. A tapered portion forms a part of the entry of the wave guide and couples the electromagnetic radiation emanating from the source to the waveguide. The electromagnetic radiation passing from the exit of the waveguide is captured and directed to a detector for analysis.
