Abstract
Industrial fluids may be monitored at the site of each industrial fluid by introducing a sample of the industrial fluid into a device employing a detection technique for detecting at least one composition within the sample. The detection technique may be or include surface enhanced Raman scattering (SERS), mass spectrometry (MS), nuclear magnetic resonance (NMR), ultraviolet light (UV) spectroscopy, UV spectrophotometry, indirect UV spectroscopy, contactless conductivity, laser induced fluorescence, and combinations thereof. In one non-limiting embodiment, a separation technique may be applied to the sample prior to the introduction of the sample into the device for detecting the composition.
