Continuous-wave cavity ring-down spectroscopy uses the behavior of laser light passed through a gas sample to provide fast and accurate measurements of contaminants down to parts per trillion (ppt) levels.

Knowing the viscosity of an oil allows you to determine its condition; we evaluate a real-time viscosity sensor and compare its results with those generated using a lab rheometer.

By keeping tabs on your equipment's lubricating fluids, you can prolong the operating life of your machinery and reduce the cost of ownership.

The demand for sensitive, low-power, low-cost gas sensors that respond quickly to appropriate stimuli is growing. Macro scale components and conventional manufacturing techniques cannot provide sensors that deliver the detection levels and low-power operation increasingly required by today's applications. And many of these sensors are prone to false alarms. However, manipulating sensing events at the molecular level avoids most problems associated with the more traditional sensor technologies.

Archer Daniels Midland Co. (ADM) makes ingredients for human food and animal feed, as well as renewable fuels and naturally derived alternatives to industrial chemicals. In 1971, ADM acquired Corn Sweeteners Inc., Cedar Rapids, Iowa, which it subsequently expanded into ethanol production.
