Smart Cuvettes
Oct 2007
SpectrEcology LLCRequest Info
DUNEDIN, Fla., Oct. 3, 2007 -- SpectrEcology LLC said it has released the first "smart cuvettes" that measure pH and pO2. The pHuvette is an optical pH sensor embedded in the wall of a standard 1-cm cuvette. The sensor is a proprietary nanomaterial that traps bromcresol green pH indicator ions in a hydrophilic sol-gel cage.

The pHuvette can be used with any spectrophotometer to provide accurate stable measurements of the pH of the fluid contained in the cuvette.

pHoxyvette is a smart cuvette with an embedded oxygen sensor. Hydrophobic sol gel traps a ruthenium fluorescent compound. Oxygen is determined using phase fluorimetry to measure the fluorescence quenching. pHoxyvette has both pH and pO2 sensors.

SpectrEcology offers 1- cm disposable smart cuvettes but can install the sensors in any transparent container wall. Complete systems include spectrometers and phase fluorimeters, fiber probes and cuvette holders.

Smart cuvettes are suitable for measuring respiration rates, biological oxygen demand (BOD) or chemical oxygen demand (COD), water quality, or the gaseous environments of sealed systems such as CO2 lasers.

SpectrEcology distributes Ocean Optics miniature spectrometers, fiber optics, chemical sensors ultrafast laser pulse characterization and laser-induced breakdown spectroscopy equipment throughout the US. It also develops products based on optical sensing for field science, in-situ or environmental applications.
