HM-536 Calcium Carbonate Content Chamber provides an easy and quick determination of calcium carbonate (CaCO3) content of soils. The test is often used as an index to the presence and quantity of calcium carbonate in marine soil specimens, expressed as the percent calcite equivalent.
The method involves treating a one-gram soil specimen with hydrochloric acid (HCI) in an enclosed reactor vessel. Carbon dioxide gas is generated from the reaction between the acid and carbonates in the specimen when the chamber is tilted and agitated, and the resulting pressure is measured. The 10psi (69kPa) Bourdon-tube pressure gauge is pre-calibrated with reagent grade calcium carbonate. The 2.5x5.5in (63.5x140mm) IDxH clear acrylic chamber assembly is sealed to the anodized aluminum end caps with O-rings, and secured by threaded rods and knobs. HM-536 is supplied with the pressure gauge, bleed valve, and a 20ml cup with handle.
