Abstract

입자를 함유한 시료 흐름에 연속 광과 단속 광을 조사하여 각각 입자의 특징 파라미터(parameter)의 검출과 입자상의 촬영을 행하는 경우에, 단속 광의 영향으로 인해서 착오된 특징 파라미터가 검출되는 것을 방지한다.
입자를 함유한 시료를 시료 흐름으로 변환시키는 시드 플로우셀과, 상기의 시료 흐름을 연속적인 광(빛)에 의해서 조명하는 제1광원과, 제1광원으로 조명된 입자로부터의 광을 검출하여 입자의 특징을 나타내는 입자신호로 변환시키는 광 검출기와, 상기의 시료 흐름을 순간적인 광(빛)에 의해서 조명하는 제2광원과, 제2광원으로 조명된 입자를 촬영하여 입자상을 얻는 촬영기와, 상기의 입자신호와 입자상을 입자분석용 데이터로 하여 입자분석을 하는 분석부를 구비하고, 그 분석부는 제2광원의 발광시에 얻어진 광검출소자로부터의 입자신호를 입자분석용 데이터로서 불채용하는 금지부를 구비한 것을 특징으로 하는 입자분석장치.
