Abstract

In a rotary particle depositor for the routine analysis of electrically or magnetically polarised or polarisable particles entrained in a liquid medium by precipitating the particles from the liquid with a magnetic or electric force field onto a substrate (5), while rotating the substrate (5) to move the liquid medium across the substrate surface, a flexible air-impermeable annular skirt (12) is used to temporarily hold the substrate (5) over the source (2) of the force field by creating a partial vacuum within the skirt (12) under the substrate (5).
