Abstract

Un proceso para medir concentraciones de partículas en un gas usando un eyector (11) para producir un flujo (14) de muestra esencialmente constante y para mezclado eficiente de la muestra que contiene partículas y un gas (13) ionizado, esencialmente limpio. La invención se refiere también a un aparato que implementa tal proceso. El proceso y el aparato pueden ser utilizados por ejemplo en la medición de concentraciones de partículas en un sistema de escape de un motor de combustión.
