Claim:
1. An apparatus comprising: a sample chamber that holds a liquid sample of which at least one analyte concentration is to be determined; a single axis colorimetric channel configured to provide a red-red colorimetric mode, a blue-blue colorimetric mode, a green-green colorimetric mode, and at least one mixed colorimetric mode, wherein the colorimetric channel further includes: a controller that is configured to selectively control which one of the red wavelength range, the blue wavelength range, or the green wavelength range is emitted by the multicolor light source, selectively controls which one of the red wavelength range, the blue wavelength range, or the green wavelength range p is detected by the multicolor detector, and determines the at least one analyte concentration of the liquid sample based on at least the selected one of the red wavelength range, the blue wavelength range, or the green wavelength range detected by the multicolor detector, wherein in a first mixed colorimetric mode the controller further controls the multicolor light source to emit light in the green wavelength range and controls the multicolor detector to detect light in the red wavelength range, wherein in a second mixed colorimetric mode the controller further controls the multicolor light source to emit light in the green wavelength range and controls the multicolor detector to detect light in the blue wavelength range, wherein in a third mixed colorimetric mode the controller further controls the multicolor light source to emit light in the red wavelength range and controls the multicolor detector to detect light in the green wavelength range, wherein in a fourth mixed colorimetric mode the controller further controls the multicolor light source to emit light in the blue wavelength range and controls the multicolor detector to detect light in the green wavelength range.
