Abstract
The present invention relates to a method for analyzing mixtures of components by a process selected from the group consisting of flow based separation processes and flow analysis processes. The method comprising the steps of:obtaining measurement signals by measuring process conditions at a plurality of positions throughout the system;applying signal processing to the measurement signals, said signal processing comprising multivariate data analysis for condensing the plurality of measurement signals to a smaller number of main signals being non-correlated;logging said main signals; anddisplaying said main signals versus time, where changes of said system conditions are indicated by one or more of the displayed main signals;detecting any error occurrence during an on going process, anddetermining what part of said system cause said error.
