In-vessel fibre optic UV dissolution
testing
The latest word in simplicity for dissolution testing uses the arch fibre optic system which resides inside the vessel, continuously monitoring photrometric changes
Opt-Diss is the latest word in simplicity for dissolution testing, using the arch fibre optic system, says Presearch The Arch probe resides in the dissolution vessel and photometric changes are monitored continuously in real time

There is no need to remove sample from the vessel, which makes it easier to monitor short time course dissolution profiles.
The software is Windows 2000/NT compatible and the method parameters and calibration information is permanently linked to data.
Data collection is rapid (10-20 sec, all channels) with real time display of absorbance, light intensity, %dissolved and concentration.
Data can be exported in standard format to Excel or other Windows programmes.
Using Opt-Diss eliminates the need for particulate removal.
In turbid solutions where the turbidity contributes to the sample UV absorbance, but the interference is constant across the UV spectrum, Opt-Diss can be used without filtration.
