Abstract:
1. An apparatus for measuring physical properties of a suspension of particles in a liquid sample comprising A) a flow through measurement cell comprising a bore into which said liquid sample is injected through an injection port, and out of which said liquid sample passes through an outflow port; B) a scattering light source that emits a scattering light beam directed to pass along the bore of said measurement cell, illuminating said liquid sample; C) one or more light scattering detectors positioned to measure light scattered from said scattering light beam by said particles in said liquid sample; D) a UV light source that emits a UV light beam directed to pass through the bore of said measurement cell illuminating said liquid sample, wherein the wavelength of said UV light beam is different from the wavelength of said scattering light beam; E) optical means directing said UV light beam to pass through said bore one or more additional times; and F) a UV detector positioned to measure light transmitted through said liquid sample by said UV light beam after said transmitted UV light beam has passed through said measurement cell a plurality of times.
