    Notes: Abstract The cross sections for Bhabha and Møller scattering have been investigated in the energy range 2.1–2.4 MeV using monoenergetic positrons and electrons to search for hypothetical resonances superimposed to the continuum predicted by quantum electro dynamics. Bhabba-to-Mott, Møller-to-Mott and Møller-to-Bhabha cross section ratios were measured. The Bhabha-to-Mott ratios could be determined with statistical errors of typically 1% and remaining systematic errors not exceeding the statistical ones. No resonances in Bhabha scattering were observed. Limits for the intrinsic widths of hypothetical resonances are given. For the first time upper limits are deduced from our data for hypothetical resonances in the Møller scattering cross section in the MeV range. Additionally, Møller-to-Bhabha cross section ratios could be determined with good precision. A good agreement between the experimental and theoretical Møller-to-Bhabha ratios can be stated calling in question the recently predicted existence of series of narrow, unresolvable resonances in the Bhabha scattering cross section.

    Spectrophotometric flow injection analysis of formaldehyde in aqueous solutions using 3-methyl-2-benzthiazolinone hydrazone (1993)

    Notes: Summary A flow injection method for the determination of formaldehyde was developed. It is based on its reaction with 3-methyl-2-benzthiazolinone hydrazone (MBTH) to yield a blue formazan anion. Typically 180 μl samples are injected into a buffered carrier stream with a frequency of 30 per hour. This sample line merges with the reagent stream containing MBTH, whereupon an azine is formed. After merging with a second stream containing an acidic solution of FeCl3 as reagent, MBTH is oxidized to an intermediate that attacks the azine yielding the formazan dye with an ɛmax at 635 nm. The method was applied to formaldehyde concentrations in the range from 0.15 mg/l to 15 mg/l. The relative standard deviation was 2.3% for 3 mg/l formaldehyde, and 5.1% for 0.3 mg/l, respectively. Strong reducing agents like nitrite interfere seriously. Out of the family of carbonyl compounds only acetaldehyde and propionaldehyde cause strong positive interference.
