Rise-time Measurement Instrument Stig
RISE TIME – A Key Attribute of Dry-Powder Device Performance and Testing
Compendial methods of testing DPIs call for an abrupt start to the air flow through the inhaler and into the cascade impactor. This procedure is logical because real users do the same. It is recognized, of course, that this “in vitro” compendial testing cannot truly simulate real patient use. However, product developers will maximize the value of this quality control test if the drug product exits the DPI in a time frame similar to that of real users. It is the RISE TIME measurement accomplished by STIG that enables this evaluation to be made. This evaluation can lead to productive adjustment to devices still under development and can lead to better designed and controlled quality testing of registered drug products.
Experimental and computational studies of the RISE TIME in compendial testing are continuing to elucidate the relationship of device characteristics and the test system itself. These studies are critical because the device and the cascade impactor and connecting plumbing components together comprise a unique fluid mechanical system, one that does not exist in real patient use. The STIG instrument offered by FIA enables real-time experimental investigation of these important fluid flow dynamics, dynamics that can transpire in under 100 millisecond.
Now, more than ever, FIA’s NEW Laminar Flow STIG enables millisecond response times, with no thermal lag, giving users unprecented accuracy in making this measurement.
A training programme is offered together with the instrument, which helps the user to understand its usage and our experts will help you get started understanding how to setup your measurement.
