We exploit this phenomenon to develop an analytical procedure employing a homemade LED-based photometer comprising a blue LED ([lambda] = 474 nm) as the radiation source and a 0PT301 photodetector.
While LM-79 does allow use of a photometer, which is a less expensive alternative than a spectroradiometer, this configuration provides no chromaticity data.

The entire probe can be immersed in the process and still provide an efficient, simple, serviceable and easy Interface between the sample and a spectrometer or photometer. This is accomplished by the high optical efficiency (>50%, 900 to 1650 nm), rugged design, external Fiber Optic connections and an optical lens isolated from the sample by an easily replaceable window.
The t-values resulted to p-values, which are lesser than 0.05, indicating that there is a significant difference between the electrolyte values of both sodium and potassium using the flame photometer and ion-selective electrodes.
