Rapid, simple and inexpensive technique for combustion analysis of organic materials in oxygen atmosphere - For determination of sulfur, halogens, phosphorus, traces of metals, etc., in organic substances by combustion in oxygen - Complies with ASTM Standard E 205 Procedure converts organic materials into soluble combustion products, which are then analyzed for chlorine, bromine, iodine, fluorine and sulfur by inorganic, gravimetric or volumetric methods. Combustion products are free from metallic contaminants. Heavy-wall conical flask, of borosilicate glass, has deep, bell-shaped, flaring lip. Elongated ground glass stopper has attached U-shape platinum wire gauze sample carrier.
