Measurements on liquid solutions using low cost, low power, light emitting diode photo-acoustics
We have developed a low cost, low power, photo-acoustic cell using a light emitting diode (LED) light source with monotone modulation for the purpose of measuring concentrations of aqueous liquid solutions in a non-invasive manner. The apparatus is smaller and cheaper than a conventional instrument...

Summary: | We have developed a low cost, low power, photo-acoustic cell using a light emitting diode (LED) light source with monotone modulation for the purpose of measuring concentrations of aqueous liquid solutions in a non-invasive manner. The apparatus is smaller and cheaper than a conventional instrument such as a photo-acoustic cell in conjunction with a spectrometer. |
