Abstract
An appts. for measuring traces of mercury contd. in a gas, e.g. natural gas, incorporates a circulation system in which there are two traps, contg. gold wool, in series. The first trap acts as a sampling trap, the second as a measuring trap. Both traps can be cooled so that they retain traces of mercury contd. in the gas under test and heated so that the mercury can be driven out. An atomic absorption spectrophotometer is placed after the two traps, in series with them, detecting in a measuring cell the traces of mercury contd. in a vector gas after it has passed through the traps. The appts. includes also a means of standardisation, e.g. a permeation tube delivering a fixed quantity of mercury into the first trap. System provides measurement and control simply and automatically of traces of mercury which could cause corrosion of heat exchanger tubes when processing the natural gas.
