  The present invention discloses a method for measuring an amount of an objective component to bemeasured in a sample, which comprises; preventing an electric charge in an atmosphere in a photometry chamber from transferring to the surface of a solution which generates light due to an energy variation of a substance induced by the objective component in the sample, measuring value of the light, and determining an amount of the objective component in the sample on the basis of the measured value thus obtained, and an instrument used for the method. According to the present invention, in measurement of an objective component in a sample using a spectrophotometer, problems such as between-day variation of signal values or increase of background value, etc. can be solved, and a trace component can be measured in high accuracy and high sensitivity.

  本发明公开了一种测量样品中待测客观成分含量的方法，该方法包括：防止光度测量室中大气中的电荷转移到溶液表面，该溶液因样品中客观成分引起的物质能量变化而产生光；测量光值；根据由此获得的测量值确定样品中客观成分的含量；以及用于该方法的仪器。 根据本发明，在使用分光光度计测量样品中的客观成分时，可以解决信号值的日间变化或背景值增加等问题，并且可以高精度、高灵敏度地测量痕量成分。
