The invention provides a pre-concentration tandem arrangement for measuring
zinc by emission
spectroscopy and an
analysis method, and the pre-concentration tandem arrangement comprises a
tungsten pre-concentration device, an electrothermal
vaporization device, a
torch interface, a carrier gas
mass flowmeter, an auxiliary gas
mass flowmeter, a diverter three-way, a converging three-way, a carrier gas channel, an auxiliary gas channel and the like. An
inductively coupled plasma emission spectrometry for measuring
solid sampling of the
zinc comprises the steps of dehydrating and
ashing a sample to be measured in air to obtain inorganic residues; heating the sample residues at about 1600 DEG C under an
argon hydrogen mixture
atmosphere, the evaporated
aerosol containing
zinc atoms contacts with
tungsten filament, and the zinc is pre-concentrated by the
tungsten filament; heating the temperature of the
tungsten filament to be about 1800 DEG C, releasing the zinc atoms, and analyzing the content of the zinc by the
inductive coupling plasma emission
spectrograph. The pre-concentration tandem arrangement has a simple structure and the problems that a
plasma torch is extinguished and a
signal is unstable when the tungsten pre-concentration device and the electrothermal
vaporization device are in combination with the
inductively coupled plasma emission spectrometry are solved. The pre-concentration tandem arrangement has the advantages that the
digestion treatment is not needed to be performed on the sample, the trace zinc in the sample can be measured, and the pre-concentration tandem arrangement has the characteristics such as being direct, speediness, high sensitivity and good stability.
