The Delphian Rainbow system utilizes new proprietary technology to sample in situ. These include sampling methods and data acquisition. More information on these can be found in our patents below.

Dynamic Data Acquisition and Presentation
Delphian has been granted a US patent protecting its real-time display of dissolution curves during data collection. This technology gives the user instant feedback on the progress of the dissolution test. This allows the user to quickly spot potential errors in the setup of the experiment or equipment rather than having to wait for results from off-line HPLC analyzers.
US Patent Number 6,558,957

Hollow Shaft Measurement
Delphian has patented a method for placing the UV dip probe within the hollow
shaft of a USP paddle stirrer. This enables the Rainbow to acquire data without creating hydrodynamic artifacts that may negatively influence dissolution measurements.
US Patent Number 6,174,497
