  • PHOTOMETER WITH LED LIGHT SOURCE
    Publication number: 20160266032
    Abstract: A photometer is provided for measuring the concentration of a chromophore in a fluid. The photometer includes a light source, a sample cell and a detector. The light source includes first, second, third and fourth light emitting diodes (LEDs). Each of the first and second LEDs emit light at a measurement wavelength and each of the third and fourth LEDs emit light at a reference wavelength. The first and second LEDs are arranged diagonal to each other and the third and fourth LEDs are arranged diagonal to each other. The photometer performs a routine for correcting concentration measurement for LED drift.
