Abstract: Apparatus for Determining Compositional Properties of a Material An apparatus, such as a flow cytometer, for determining compositional properties of a material (38), comprises sensing means (24) having an output responsive to components of interest within a sample, here liquid (38), at a measurement location (22). A flow regulator such as a pump (36) is provided in flow communication with the measurement location (22) and with the liquid sample (38). Control means (34) is adapted to analyse, such as by employment of an pulse height analyser (32), the output to determine a contribution thereto by noise and to control the operation of the flow regulator (36) to regulate presentation of the sample, here the flow rate, at the measurement location (22) in a manner dependent on the determined noise contribution.

Abstract translation: 用于确定材料的组成性质的装置用于确定材料（38）的组成性质的装置，例如流式细胞仪，包括感测装置（24），其具有响应于样品内的感兴趣组分的输出，这里是液体（38 ），在测量位置（22）。 设置有诸如泵（36）的流量调节器与测量位置（22）和液体样品（38）流动连通。 控制装置（34）适于例如通过使用脉冲高度分析器（32）来分析输出以确定噪声对其的贡献，并且控制流量调节器（36）的操作以调节样品的显示 ，这里是以取决于所确定的噪声贡献的方式在测量位置（22）处的流量。
