Zusammenfassung:The invention relates to a miniaturized mercury analyzer based on optical emission spectrometry in capacitively coupled plasma micro-torch and gold filament micro-collector used as analytical instrumentation. According to the invention, the analyzer consists of a capacitively coupled plasma micro-torch (1) with the role of excitation cell, a gold filament micro-collector (2) for concentrating the mercury vapours, a source (3) for supplying the micro-collector (2), a radiofrequency generator (4), a micro-spectrometer (5) with coupled load detector for measuring the mercury emission signal, a computing unit (6), a three-channel peristaltic pump (7), a cold vapour generator (8), some recipients (9, 10, 11 and 12) for the sample, for stannous chloride, for washing solution and for residue collecting and an electronic flowmeter (13) for argon.
