3.2 Amalgamation -- The process by which mercury forms a metal alloy with gold.
3.3 Amalgamator -- A system composed of gold particles at a high surface area to
volume ratio for the purpose of amalgamating mercury vapor.
3.4 Primary calibration -- A complete calibration of the instrument’s working range. This calibration is performed initially and when any significant instrumental parameters are changed. For example, in this method a primary calibration should be performed after the decomposition tube, amalgamator, or oxygen tank is replaced.
