    • An apparatus for detecting analytes in a sample is provided. The apparatus can include: a flow cytometry system including one or more detection zones; one or more irradiation sources disposed for irradiating the one or more detection zones with radiation; at least one detector disposed for collecting charges corresponding to light signals emitted from detectable analytes in the one or more detection zones, which have been excited by the radiation, wherein at least one detector includes an output; a system coupled to the at least one detector for effecting time delay integration of the charges by accumulating the charges before reading the charges at the output of the at least one detector; and a sorting mechanism, for example, to effect flow cytometry. Methods for detecting analytes in a sample are also provided.
    • 提供了一种用于检测样品中分析物的装置。 该装置可以包括:流式细胞术系统,其包括一个或多个检测区域; 一个或多个辐射源被设置用于用辐射照射一个或多个检测区域; 至少一个检测器,其被设置用于收集对应于已被所述辐射激发的所述一个或多个检测区域中的可检测分析物发射的光信号的电荷,其中至少一个检测器包括输出; 耦合到所述至少一个检测器的系统,用于通过在读取所述至少一个检测器的输出端的电荷之前累积电荷来实现电荷的时间延迟积分; 以及分选机制,例如进行流式细胞术。 还提供了检测样品中分析物的方法。
