Abstract

a presente invenção se refere a um método e a um aparelho para espectroscopia de emissão óptica de fluidos. o método compreende condução de um fluxo de amostra de fluido (1) através de uma célula de fluxo (2); aplicação de energia eletromagnética (3) a partir de uma fonte (4) para energia eletromagnética em cima de uma superfície (5) do fluxo de amostra de fluido (1) que flui através da célula de fluxo (2) para induzir plasma (6) no fluxo de amostra de fluido (1) que flui através da célula de fluxo (2); e recepção de luz (7) emitida pelo plasma (6) e análise de luz (7) emitida pelo plasma (6) em um espectrômetro (8) de um sistema de espectroscopia (9). em concordância com a presente invenção, o método compreende provisão de uma parede de proteção (10) entre o fluxo de amostra de fluido (1) que flui através da célula de fluxo (2) e do espectrômetro (8) do sistema de espectroscopia (9) de maneira tal que um espaço intermediário é formado entre a parede de proteção (10) e o fluxo de amostra de fluido (1) que flui através da célula de fluxo (2); e provisão da parede de proteção (10) com uma abertura (11) para possibilitar que luz (7) emitida pelo plasma (6) venha a passar através da parede de proteção (10).The present invention relates to a method and apparatus for optical emission spectroscopy of fluids. the method comprises conducting a fluid sample flow (1) through a flow cell (2); applying electromagnetic energy (3) from a source (4) for electromagnetic energy upon a surface (5) of the fluid sample stream (1) flowing through the flow cell (2) to induce plasma (6) ) in the fluid sample flow (1) flowing through the flow cell (2); and receiving light (7) emitted by plasma (6) and analyzing light (7) emitted by plasma (6) on a spectrometer (8) of a spectroscopy system (9). In accordance with the present invention, the method comprises providing a protective wall (10) between the fluid sample flow (1) flowing through the flow cell (2) and the spectroscopy system spectrometer (8) ( 9) such that an intermediate space is formed between the protective wall (10) and the fluid sample flow (1) flowing through the flow cell (2); and providing the protective wall (10) with an opening (11) to enable light (7) emitted by the plasma (6) to pass through the protective wall (10).
