Abstract

Предлагается модуль (21) представления жидкой пробы для анализа посредством спектроскопии лазерно-индуцированного пробоя (LIBS). Модуль (21) представления имеет входное отверстие (22, 27) для обеспечения потока (25) жидкой пробы из технологического потока, измерительное отверстие для взаимодействия с измерительными оптическими устройствами (31, 32, 33, 34) и стабилизирующую поверхность (26), обращенную к измерительному отверстию. Стабилизирующая поверхность (26) формирует стабилизированный поток пробы вдоль стабилизирующей поверхности так, что стабилизированы глубина и наружная поверхность потока 25 пробы и уменьшены поверхностные флуктуации и вариации глубины стабилизированного потока пробы суспензии. Поскольку лазерные импульсы (29) фокусируются на наружной поверхности плоского потока (25) пробы для преобразования по меньшей мере части пробы в состояние плазмы, точность и воспроизводимость LIBS-измерений значительно повышаются благодаря стабилизированному потоку пробы.
