TABLET/LIQUID SAMPLE ANALSYER
- SERIES T
|The Ventacon T2 Autochanger Tablet Analyser
The Ventacon Autochanger Analyser
allows the user to analyse several tablets or liquids in tubes in succession. The
accessory is automatically driven, enabling the user to leave the accessory running
unmanned for several hours.
Tablets are rotated and moved up and down as they are examined.
The Raman spectrum is the average across the whole scanned area of the tablet surface. The
amplitude of vertical movement is adjustable in several steps. This tablet analyser can
therefore be used for a wide range of tablet sizes. Liquids can be rotated or kept fixed
in their tubes, but in this case no vertical movement is required.
A stepper motor-driven carousel is used to auto-change samples. The
carousel holds 20 tablets or tubes. It moves to drop tablets, one at a time, into
position for study. The carousel sits on the top of the accessory. One carousel unit is
required for each tablet size. The rotator and vertical translator lie beneath the
carousel. You will see in the photo above that 2 white tablets remain in the carousel.
Beneath it one tablet is in place in the rotator and being examined by the spectrometer.
The brass component to the right of the accessory is an eccentric driven by a small
motor/gearbox behind it. An arm and follower is moved up and down by the
eccentric. This in turn moves the whole carousel.
