One carousel unit is required for each tablet size. In Figure 2 you will notice that the system is split into 2 parts. The carousel lies to the right. The system relies on a tomed sequence. This is initiated by a hand-shake from the spectrometer indicating that the Raman analysis is complete.
Carousels are tailor made to suit the individual users tablet sizes.
Tablets can be round, lozenge shaped or cylindrical. They can vary between 15 and 100 mg in weight. Changing the carousel from one tablet size to another takes approx. 3 minutes to complete. The accessory needs considerable support.
