The FDA guideline for nasal sprays is to disable Multiple Scattering
Analysis.
.
The Data Handling options allow for refining the measurement further
and are detailed in Chapter 6 and in the online help. There are three tabs:
Alarms – configures the system to log a warning or error if transmission or
scattering fall to specified levels:
Data handling – used to “kill” (discard) data from specified detectors.
Spray profile – lets the user define the path length of the laser beam
through the spray, providing a more accurate measure of the spray
concentration. Advanced options allows users to specify the spray plume
geometry, improving the accuracy of data analysis.
Specify any required parameters and click Next.
.
The second Analysis dialogue appears, as shown below. Only change the
Curve fit from No fit if the Rosin-Rammler or Log-Normal size distribu
-
tion models are to be used to interpret the recorded size distributions.
Chapter 10 has more information on this.
