1. A method of characterising particles in a sample, comprising:
obtaining a plurality of scattering measurements, each scattering measurement comprising a time series of measurements of scattered light from a detector, the scattered light produced by the interaction of an illuminating light beam with the sample;
identifying contaminated scattering measurements, in which a contaminant was contributing to the scattered light; and
determining a particle characteristic from scattering measurements that have not been identified as contaminated scattering measurements by:
determining an autocorrelation function for each scattering measurement that has not been identified as a contaminated scattering measurement;
combining the autocorrelation functions to produce an average autocorrelation function from which the particle characteristic is derived.
