An instrument and method for accurately measuring target analyte levels is a gas sample over an extended range. The instrument includes (i) a sensor effective for detecting the analyte, and (ii) a barrier film having limited permeability for the analyte covering the inlet orifice on the sensor for reducing the flux of analyte into the sensor. The method involves (a) sensing the flux of target analyte passing through the barrier film and into sensing contact with the sensor, and (b) reporting a concentration of analyte by multiplying a concentration value previously correlated to the sensed flux by the flux reduction factor of the barrier film.

Instrument and method for measuring high concentrations of carbon monoxide in a gaseous sample

A sheet of sensors and a method of manufacturing such sheet of sensors. The sheet is configured with (A) a tessellated zipper pattern of identically shaped elements defining (i) a right longitudinal column consisting of a base portion of a right set of elements, (ii) a left longitudinal column consisting of a base portion of a left set of elements, and (iii) an intermediate longitudinal column consisting of alternating tab portions of the right and left elements, and (B) a continuous longitudinal strip of functional material positioned only within the intermediate column.
