Abstract
A method for analyzing a gaseous electronegative species comprises the steps of providing an analysis chamber; providing an electric field of known potential within the analysis chamber; admitting into the analysis chamber a gaseous sample containing the gaseous electronegative species; providing a pulse of free electrons within the electric field so that the pulse of free electrons interacts with the gaseous electronegative species so that a swarm of electrically charged particles is produced within the electric field; and, measuring the mobility of the electrically charged particles within the electric field.
Claims5
A method for determining the makeup of a mixture of known refrigerants comprising the steps of:
- providing an analysis chamber;
- providing an electric field of known potential within said analysis chamber;
- admitting into said analysis chamber a gaseous sample containing a mixture of known refrigerants;
- providing a pulse of free electrons within said electric field so that said pulse of free electrons interacts with said mixture so that a swarm of electrically charged particles is produced within said electric field;
- measuring the mobility of said electrically charged particles within said electric field;
- and,
- comparing said measurement to data obtained from mixtures of said refrigerants having known makeup.
