Fast Isoprene Sensor Models

The Fast Isoprene Sensor FIS-Auto has an automated calibration system which uses an on-board microprocessor and electronic valving for automatic calibrations up to 12 times per day, allowing unattended or remote operation. A low flow model, FIS-Auto-cuvette is capable of low sample rates (down to 150 sccm) for monitoring isoprene in single-leaf cuvette systems.

FIS-Auto   $38,000 Complete FIS instrument, operation manuals & graphical control software   * Ultra-low-noise digital photon counting optical system with serial (RS-232) output * Electronic mass-flow control of: sample air, O2 and isoprene standard * Flow output: 0-5V analog and LCD readout, three-channels * Two-channel catalytic converter for instrument zero and O3 conversion * Digital control of sample inlet/reaction cell and catalyst temperatures * Integral dynamic-dilution calibration system * All Teflon/stainless flow system * Microprocessor-controlled, brushless, DC pump * Swagelok stainless fittings throughout * Powder-coated aluminum instrument rack * Microprocessor-controlled autocalibration for unattended operation * Graphical PC interface (LabView 6i, executable and source code included) for data acquisition and control with user selectable integration (0.1 to 20 seconds). FIS-Auto is used for isoprene monitoring at ground level, on towers, in chamber studies, and as a breathalizer. The instrument is weather resistant and is used for general, continuous, isoprene monitoring. An on-board microprocessor-controlled calibration system provides instrument zero and calibration up to 12 times per day, allowing unattended or remote operation for extended periods, providing continuous and extremely accurate isoprene data without intervention. FIS-Auto also accepts external logic signals to perform calibrations on any user defined schedule. This instrument is weather resistant and suitable for all isoprene monitoring situations including cuvette, chamber, ambient, tower, aircraft and long duration experiments. Sample inlet flow is 4 slpm nominal.

FIS-Auto-Cuvette   $38,000 Complete FIS instrument, operation manuals & graphical control software   FIS-Auto-Cuvette is a low-flow version of FIS-Auto, it is capable of air sampling down to 150 sccm which is necessary when monitoring isoprene in leaf-cuvette systems or other low-flow applications. This is achieved through use of an alternative internal plumbing scheme. Sample flow range: 150-2000 sccm.
