  The present analysis method for analyzing a sample (Sa) uses capillary electrophoresis by applying a voltage to a sample solution introduced to a micro flow path, performing separation analysis for a component contained in the sample solution, and measuring an optical measurement value at a measurement section of the micro flow path corresponding to an elapsed time after a start of measurement. The analysis method comprises a waveform forming step (S31) of forming a waveform related to the optical measurement value corresponding to the elapsed time since the start of measurement; an interface detection step (S32) of determining an interface detection time based on the optical measurement value when an interface between the sample solution and a migration liquid (Lm) reaches a predetermined measurement position in the micro flow path; a waveform feature specification step of specifying a plurality of waveform features appearing in the waveform; and a component identification step (S34) of identifying the component contained in the sample solution based on elapsed times corresponding to each of the waveform features as well as the interface detection time.

  本分析样品的分析方法（Sa）使用毛细管电泳，对引入微流路的样品溶液施加电压，对样品溶液中所含成分进行分离分析，并在微流路的测量部分测量与测量开始后的经过时间相对应的光学测量值。分析方法包括：波形形成步骤（S31），形成与光学测量值相关的波形，该光学测量值与测量开始后的经过时间相对应；界面检测步骤（S32），当样品溶液和迁移液体（Lm）之间的界面到达微流道中的预定测量位置时，根据光学测量值确定界面检测时间；波形特征指定步骤，指定出现在波形中的多个波形特征；以及成分识别步骤（S34），根据与每个波形特征对应的经过时间以及界面检测时间，识别样品溶液中所含的成分。

  A determination method includes: using a microchip, including a capillary flow path and a sample reservoir connected to the capillary flow path at an upstream side, to fill the capillary flow path with a first solution for electrophoresis, and supply the sample reservoir with a second solution containing an analyte; applying a voltage between the sample reservoir supplied with the second solution and the inside of the capillary flow path filled with the first solution, to move a component contained in the second solution in the capillary flow path and separate the component in the capillary flow path; optically detecting a value related to a component difference between the first solution and the second solution, other than a value related to the analyte, for the separated component; and determining whether the optical detection is favorable or poor by comparing the optically detected value with a predetermined threshold value.

  一种测定方法包括使用微芯片，包括毛细管流路和在上游侧连接到毛细管流路的样品贮存器，向毛细管流路注入电泳用第一溶液，并向样品贮存器提供含有分析物的第二溶液；在提供第二溶液的样品贮存器和注入第一溶液的毛细管流路内部之间施加电压，使第二溶液中含有的成分在毛细管流路中移动，并分离毛细管流路中的成分；光学检测被分离组分的与第一溶液和第二溶液之间的组分差异有关的值，而不是与分析物有关的值；以及通过将光学检测值与预定阈值进行比较，确定光学检测结果是好是坏。
