Ocean Optics' (www.oceanoptics.com) new Lab-on-Valve sequential-injection analyzer puts a computer controlled six-position selector valve, precision syringe pump, and spectrophotometric flow cell in a 12.7- x 15.3- x 15.3-cm package for automated wet-chemistry applications. With processing taking place within the valve manifold, there is no need for additional tubing and connectors, so microvolumes of samples don't travel long distances with increased potential for contamination or degradation. Applications include biological processing medical immunoassays, water quality analysis, and dilution monitoring.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
