Midi- designed for 50 mL or less of aqueous samples where concentrations have exceeded calibration standards
• Purge tube capacity: 50 mL
For removing interfering substances in quantitative analysis of various industrial waste waters, saline and reagent grade water. Cyanide is released as HCN acid from cyanide complexes by means of reflux-distillation and absorbed in a scrubber containing a sodium hydroxide solution. Apparatus includes a reactor head, cold-finger condenser, dispersion tube with coarse porosity frit and two purge tubes.
For removing interfering substances in quantitative analysis of various industrial wastewaters, saline and reagent grade water.
Samples react with acid to produce HCN acid. The first bubbler acts as a scrubber to remove sulfides. Cyanide is absorbed in the second bubbler.
Apparatus includes inlet tube, reflux body, cold-finger condenser, 1000 mL flask with center and side necks, hose adapter, scrubber tube, scrubber flask, absorber flask, dispersion tube and clamp.
