ABSTRACT:
An improved near-infrared quantitative analysis instrument includes a number of removable finger inserts each dimensioned for a different finger size, which facilitates properly aligning and fitting an individual user's finger into the optical system of the analysis instrument taking into account the size of the individual's finger. The insert according to the present invention can be also designed to accommodate samples of various substances for quantitative analyte measurement.
