4.0 Testing Procedure
4.1 Aerosol Particle Size Distribution Testing(By Malvern Spraytec)
4.1.1 Each sample should be tested with 2.5ml 0.9% saline solution for 3 minutes.
4.1.2 Add 2.5ml 0.9% saline solution into the nebulizer kit,
4.1.3 Connect the nebulizer kit with NB60Q and put at the testing site, the nebulizer
kit’s outlet must be kept at 3.0 cm from the laser beam.
4.1.4 Start recording Spraytec for more than 15 secs, then start NB60Q for testing.
4.1.5 After 3.0 minutes have been reached, stop the NB60Q and then stop Spraytec.
4.1.6 Checks Spraytec records
