16 years into the production of the Fast Isoprene Sensor one would expect things to be settled with only minor changes implemented periodically. However new insights, research, SolidWorks 3-D CAD design, materials advances, and continued scientific work challenge earlier designs and continue to improve the FIS.
In the past year -- the instrument has shrunk in size, been upgraded to a custom 6061 alloy chassis, added a 4th channel of temperature control, split out the catalytic converter into two separate units (each optimized for its function) and added efficient heat sinking to the effluent flows. The FIS circuit board has been expanded adding enhanced electronic capability. We also shock-mounted the brushless DC pump, greatly reducing acoustic noise and vibration.
The changes make for a quieter, more stable, more sensitive and easier to service instrument in an ultra-rugged compact form. We continuously strive to improve our instuments and welcome input from our customers worldwide.
