    Abstract: 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: Determination of Analytes in a Sample Matrix by Solvent Extraction A method for the assay of one or more analytes in a sample matrix comprising the steps of: performing analyte extraction on the sample matrix, said analyte extraction comprising combining the sample matrix with a solvent for an extraction period which is less than that required for reaching equilibrium; and separating the analyte containing solvent from the sample matrix; next measuring a level of analyte present in the separated solvent; and then applying in a computer a calibration by which is established a mathematical relationship between levels of analyte extracted from each of a plurality of reference samples by means of the process employed above in the extraction for the sample matrix and a reference value of the levels of analyte for each reference sample to thereby derive a measure of the level of analyte in the sample matrix. Specifically a method to determine the amount of mycotoxins in cereal grain, especially OTA (ochratoxin A) and DON (deoxynivalenol) by mixing with a solvent comprising water alcohol mixture, with 20-40% ethanol by volume.

    Abstract translation: 通过溶剂提取测定样品基质中的分析物用于测定样品基质中的一种或多种分析物的方法包括以下步骤：在样品基质上进行分析物提取，所述分析物提取包括将样品基质与溶剂 提取时间小于达到平衡所需的时间; 并从样品基质中分离含分析物的溶剂; 接下来测量分离的溶剂中存在的分析物的水平; 然后在计算机中应用校准，借助于上面在采样矩阵的提取中所采用的过程以及参考值的参考值建立从多个参考样本中的每一个提取的分析物的水平之间的数学关系 分析每个参考样品的分析物，从而导出样品基质中分析物水平的量度。 特别是通过与包含水醇混合物的溶剂和20-40％体积乙醇混合来测定谷物中特别是OTA（赭曲霉毒素A）和DON（脱氧雪腐镰刀菌烯醇）中霉菌毒素的量的方法。
