The sensitivity of a scaled-down emission spectroscopy configuration was tested with the use of (1) the fluorescence from Rhodamine 6G in ethanol and (2) the Raman emission from acetone, toluene, methanol, and water. The fluorescence results showed a linear intensity response down to a concentration of 3.17 × 10−7 mg/mL, which corresponded to sensitivity of four parts per ten billion by weight. Nonlinear signal levels extended the sensitivity almost two more orders of magnitude lower in concentration. The observation of Raman emission indicated that this system was sensitive enough to detect very weak intensities but was two to three orders of magnitude too insensitive to produce a practical Raman sensor.
