Setup
Components for Oxygen:
NeoFox Phase Fluorometer
RedEye® Oxygen Patches (Headspace and In-Solution measurement)
Bifurcated Fiber Optic probe (more…)
An investigation was performed to determine the long-term stability of the T-300 probe in seawater, as well as a comparative analysis with a Ross pH electrode. Seawater was obtained locally from a Dunedin, FL marina, and the test was performed isothermally in an environmental chamber at 25°C. An Ocean Optics USB2000 spectrometer was used with a 200?m slit and grating #2 with no lens installed. (more…)
Goal
There was an interest in non-intrusively monitoring pH in tubes containing wet soil samples. This was significant for a number of reasons; this was the first time the reflective patches were to be tested in something other than a cuvette, on a curved surface rather, and this was also the first time an analyte solution was observed that contained sediment or turbidity.

Abstract
This application note explains how oxygen concentration is measured in the headspace of organic solvents such as Acetonitrile. (more…)
A smart Oxygen Cuvette is developed by coating the inner surface of a cuvette with oxygen sensitive thin film material. The coating is glass like sol-gel based sensor that has an embedded ruthenium compound in the glass film. The fluorescence of the ruthenium is quenched depending on the oxygen level. Ocean Optics phase fluorometer, NeoFox is used to measure this rate of fluorescence quenching and computes it for the amount of oxygen present. (more…)
