Abstract

본 발명은, 노즐 출구 오프닝(3)을 통해 노즐(2) 밖으로 소규모 양자 펄스식으로 목표물(5) 상에 분석 유체(7)를 분사시키는, 목표물 상에 분석 유체를 비례적으로 공급하기 위한 장치에 관한 것이다.
지금까지 분석 유체를 위해 일반적으로 사용된 “드롭 온 디멘드”법의 경우에서 보다 실제로 더 크지만, 한편으로는, 지금까지 희석기 및 투여기를 사용하여 달성할 수 있었던 최소 용량보다 더 큰 분석 유체 양자의 정밀한 분배를 가능하게 만들기 위하여, 분석 유체를 가압하게 유지시키는 가압실를 포함하고, 위치 선정 요소(12)에 의해 운동하는 폐쇄요소(13) 및 밸브 오프닝(23)을 갖는 밸브 장치(11)가 제공되며, 밸브 오프닝(23)의 폐쇄동안 폐쇄요소(13)의 운동에 의해 유체의 분사가 지지될 정도로 밸브 장치(11)가 조립되는 장치가 제안된다.
