“…The concentration of carbon monoxide remaining in an aliquot of gas was determined by the palladium method of Wennesland (25). Recovery by this method is not quite complete (25,26), but the error does not exceed 5 per cent. The maximum error would not change the amount of residual carbon monoxide by more than 0.1 cc., which in turn corresponds to the insignificant error of 1 part in 1000 in the measurement of the total carbon monoxide absorbed.…”

“…Literature Cited Introduction Tin(II)-diphenylcarbazide was reported as a solid reagent responsive to the two common strong atmospheric oxidants of concern-ozone and nitrogen dioxide (1,2). Our efforts to develop or discover reagents for passive monitoring devices that would be specific either for ozone or for nitrogen dioxide produced 1 -methylperimidine as a specific reagent for nitrogen dioxide (3).…”

“…Reflection Absorbance Measurements. A Perkin-Elmer Model 124 visible-ultraviolet spectrophotometer modified for reflection measurements as described by Lambert et al (2,4) was used. In this instrument, the incident beam from the light source is deflected onto the reagent paper surface and then back to its original path to the photomultiplier tube.…”

“…In comparison, Figure 2 shows the extensive technical equipment used for the same purpose scarcely one hundred years ago: Martinek and his colleagues already reported a detection limit of 10 ppm in 1928, which roughly corresponds to the detection limit of the Dräger tubes ® . About a decade later, the reaction of palladium(II) chloride (PdCl 2 ) with CO was described for the first time [11]:…”
