1. A device for measuring a concentration of a compound in a sample, comprising:
- a source of electromagnetic radiation (EMR) that emits one or more than one wavelength of EMR, the source of EMR being operatively coupled to a power source;
a detachable receptor sized to receive the body part;
a holder for receiving the detachable receptor, the holder comprising one or more than one input in operable association with the source of EMR, one or more than one output in operable association with a detector, the one or more than one input and the one or more than output of the holder in optical alignment with one or more than one port located within the receptor, the one or more than one input and the one or more than output defining an EMR path through the holder and within the receptor, wherein, the sample when received by the receptor is placed within the EMR path;
the detector for measuring transmitted or reflected EMR received from the sample, the detector operatively coupled to a processing system;
the processing system comprising one, or more than one calibration algorithm for determining a concentration for the one or more than one compound, or a calibration table for determining the percent of the one or more than one compound.
