“…Sulfate was determined gravimetrically as Co(NH3)6BrSC>4 by precipitation from neutral or slightly acidic solution xvith a reagent consisting of hexamminecobalt(III) bromide, ammonium bromide, and hydrochloric acid in 75% methanol or acetone (12). Similar procedures have been developed for the determination of several other anionic substances (2,4,14,17,19) quantitatively insoluble precipitates with the ammines of cobalt(III).…”

The one-tube preamplifier, or cathode follower described by Jordan and Bell (5) was found satisfactory, although frequent replacement of electron tube 6AK5 seemed necessary. A f'entralab ceramic condenser with a 5000-volt rating was used for decoupling.Amplifier. The Atomic Instrument Co.'s Model 204A is considered excellent in this application. From the various outputs it was possible, simultaneously, to count pulses, to view them on an oscillograph, and to monitor them with a counting rate meter. A discriminator, which is essential in neutron counting, is a part of this amplifier. It was used to determine the optimum gain or pulse discrimination level for obtaining reproducible results.Scaler. A conventional Higinbotham scaler was used, with a scale of 64 or 512 according to the counting rate. A DuMont Type 248A oscillograph with triggered sweep of various durations was exceedingly helpful throughout the work.

“…Under the conditions prevailing during the determination of ferrocyanide ion by this procedure, of the commoner anions only chromate, dichromate, and metavanadate ions interfere. Parks ( 14) and Parks and Prebluda (15), in fact, suggest the use of this reagent for gravimetric quantitative determination of vanadium. Ferricyanide ion, contrary to .…”
