Title: High-sensitivity pollutants detector for industrial use - has high temp flame burning dicyane gas produced as required
Inventor: ROMBACH RUDOLF DIPL-ING
IPC: G01N21/72
Filed: 1973-10-17
Abstract: A high-sensitivity detector for chemical elements and compounds comprises a dicyane-flame photometer, which is supplied directly with the highly-toxic dicyane gas as it is produced in a closed reaction vessel from nitrogen-carbon compounds, the discharge from this vessel leading to a dicyane-oxygen burner inside the photometer. The starting materials for producing the gas are supplied to the inlet of the closed vessel. The detector can be used as a hand operated detector for pollutants in air or water, for use on a industrial (not laboratory) scale. As the gas is produced just before it is burnt, the danger is reduced. A wide range of substances can be detected, on account of the high flame temp.

IPC: G01N21/27
Filed: 1974-11-27
Abstract: In a procedure for automatically checking, functioning and zero setting of ultra-red gas analysers (e.g. those applied for analysis of mine atmospheres for CO, CO2 and CH4) a test gas is fed into an analyser at regular intervals for fixed periods from a storage bottle via a fine filter in the gas line. Afterwards gas from the atmosphere to be tested is fed to the analyser also for a fixed period but via a filter to remove the component being tested for. This zero filter is connected upstream of the fine filter. The incidence of both steps is registered on a central indicator 24 hrs. per day and the results are recorded. Zero-drift is evaluated and recorded, and can thus be corrected. A positive indication that the instrument is functioning is obtd.
