Online monitoring of aerosols with an energy-dispersive X-ray spectrometer.
A continuously working sampling and analyzing device was developed and tested. It is suitable for monitoring of metals bound to particulate matter in emissions of stack gases. The samples were precipitated on a pure quartz fiber filter tape and analyzed shortly afterwards non-destructively by an energy dispersive X-ray spectrometer (EDXRS). By using this method a wide range of elements with atomic numbers from 19 (K) to 82 (Pb) can be analyzed. New experiments have shown that the novel combined particle sampling and analysis system (X-DUST) could also successfully be used for the monitoring of toxic elements in ambient air.

Acrylamide polymerization: new method for determining the oxygen content in blood.
A new principle for determining the oxygen content of 0.1-milliliter blood samples has been developed, based on measurement of the delay in gelation during copolymerization of acrylamide and bisacrylamide initiated by free radicals. The logarithm of this time interval is linearly proportional to the oxygen content of the blood sample over the range 0 to 22 milliliters of oxygen per 100 milliliters of whole blood. Physiological variations of pH and pCO(2) do not affect the sensitivity of the assay.
