Abstract
The present invention belongs to the field of analytic instrument. The sequentially scanning no-scattering atomic fluorescence spectrometer consists of mainly the following parts: one continuous hydride generator with catalytic device for the sample for element analysis to enter; one or several units for guiding the monochromic light from different hollow cathode lamps to atomizer; one atomizer; and one fluorescence detector. The atomic fluorescence spectrometer can detect decades of elements successively and has high performance and low cost.
Description
The invention relates to the main composition of atomic fluorescence of zero dispersion spectrometer with sequential scanning function, especially guide to above the atomizer about the monochromatic light that relies on time sequencing that different hollow cathode lamps is launched, adopt novel hydrogenated thing sampling device to carry out the novel atomic fluorescence spectrometer that sample imports simultaneously.
The type atomic fluorescence spectrometer once can detect tens elements in order, is class high-performance, an atomic fluorescence spectrometer cheaply.
The present invention is as follows: novel sequential scanning atomic fluorescence of zero dispersion spectrometer is mainly by forming as the lower part: the sample that (1) new type of continuous hydride generator that has a catalytic unit is used for analytical element enters.(2) one or more monochromatic light that different hollow cathode lamps is launched are directed to the device on the atomizer in chronological order.(4) fluorescence detectors of (3) atomizers.
The device that the monochromatic light that is used for that different hollow cathode lamps is launched is directed on the atomizer in chronological order is meant down a kind of of array apparatus: the monochromatic photocon of suitable transmission that certain flexibility is arranged of (1) one or more cable shape, this cable shape photocon one end is fixed on the periphery of atomizer, is used for irradiated atoms steam.The other end can be accurately moves to the lamp holder plane of another hollow cathode lamp and can collect this monochromatic light of transmission to atomizer from the lamp holder plane of a certain hollow cathode lamp.(2) the lamp holder plane of each hollow cathode lamp all connects a photoconduction, and the other end of these photoconductions is fixed on the periphery of atomizer.By being followed successively by each hollow cathode lamp power supply in chronological order, to realize the function of fluorescent instrument sequential determination.(3) aggregate device of one or several hollow cathode lamp, this device is placed in the periphery of atomizer, plane lamp socket vertical fixing in each aggregate device has a plurality of hollow cathode lamps, and the lamp holder of these hollow cathode lamps should be on same plane, and light emission direction is identical.By accurately move the aggregate device of each hollow cathode lamp at two dimension or three-dimensional, make monochromatic light that each hollow cathode lamp on the instrument launches along with the aggregate device of hollow cathode lamp moves, successively can both make the atom on it produce fluorescence by the direct radiation atomizer in chronological order.
The new type of continuous hydride generator that has catalytic unit is meant to install on hydride generator and is used to strengthen the catalysis device that element forms the hydride ability.These catalysis devices are the principle manufacturings of using following catalysis process: (1) photocatalysis: promptly when sample solution and when going back protohydrogen generation hydrogenation, use certain intensity light, particularly ultraviolet ray to shine reaction system.(2) electrochemical catalysis: promptly when sample solution when going back protohydrogen generation hydrogenation, in reaction system, insert chemical electrode (3) catalyst: promptly use some catalyzer, make sample solution and go back protohydrogen hydrogenation (4) thermocatalysis takes place: heated sample solution and the reaction system of going back protohydrogen when having catalyzer to exist with catalytic property.By using the one or more combination in the above-mentioned catalysis process, can make other tens kinds of elements (not comprise traditionally easily nine elements A s of shape hydride, Sb, Bi, Ge, Sn, Pb, Se, high efficiency hydrogenation Cd) can both take place in Te, and realizes the hydrogenation sample introduction.
