摘要：A method of compensating a single-particle optical sizing sensor for sizingparticles in a relatively concentrated fluid suspension sample for turbidity of saidsuspension sample is described. The sensor operates on a light extinction principlewhereby a photo-detector produces a signal V LE (t) having a baseline voltage level and aresponse to blockage of light by a particle as a downwardly extending pulse from saidbaseline voltage level. The method comprises passing a non-turbid suspension throughsaid sensor, measuring a baseline voltage level V 0 produced in response to said non-turbid suspension, passing said relatively concentrated suspension sample through saidsensor, measuring a baseline voltage V 0 T produced in response to said relativelyconcentrated suspension sample, calculating the ratio G = V 0 V 0 T , and adjusting saidsensor in response to G to compensate for said turbidity when said relativelyconcentrated suspension sample passes through said sensor.
