Abstract
A dual injector for an automated immunoassay instrument is provided which allows the sequential detection of two different chemiluminescence labels within one instrument. The injector has four carefully designed orifices. The orifices are designed to work in two pairs. Orifices one and two can be used to inject trigger reagents A and B which can trigger a chemiluminescent reaction, such as acridinium. Orifices three and four can inject trigger reagents C and D for triggering a chemiluminescent reaction, such as luminol. The two pairs can be used in a sequential manner to generate signals in the wells of a cuvette. Thus, it is possible to run both acridinium and luminol based assays on one instrument.
