  • Sample pump eliminates emissions

    A compact system significantly improves analyzer accuracy. This innovative turnkey solution for analyzer emissions is a solid-state pump with an ultra-sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure — even during times of plant upset.

  • Scientific Method: Rethink Experiment Design

    The traditional approach to experimentation, often referred to as the “scientific method,” requires changing only one factor at a time (OFAT), but this method only allows one to see things one dimension at a time. By varying factors only at two levels each, but simultaneously rather than one at a time, experimenters can uncover important interactions.
