The Fast Isoprene Sensor continues to evolve with the latest designs being the most sensitive, rugged and user serviceable of our entire history.   Modifications to the flow system support ever higher flowrates. The dual catalyst design has significantly improved calibration accuracy and trace ozone from the effluent exhaust.   The use of advanced Aerogel insulation has eliminated heat leakage and improved temperature stability while decreasing power consumption.   New insights, research, SolidWorks 3-D CAD design, materials advances, and continued scientific work challenge earlier designs and continue to improve the FIS.   The instrument has shrunk in size and 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. In the past year we’ve begun controlling certain instrumental parameters with laser flow restrictors. This has boosted stability.   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 instruments and welcome input from our customers worldwide.   Alan Hills
