Literature

"The SprayVIEWTM NSx system permits a versatile range of settings for stroke length, hold time, IAD time, ctuation/return stroke velocity, and acceleration. It also monitors and records the actual force and displacement profiles for later analysis. ... The SprayVIEWTM NSP software automatically determines the contour of the spray pattern and reports all the spray pattern measurements recommended by the FDA including Dmax, Dmin, ovality, area, and center of mass (COM). ... The small standard deviations observed for these measurement results indicate that the SprayVIEWTM NSx automated actuation station is capable of delivering reproducible actuation performance thus facilitating the measurement of various nasal spray characteristics."

"Optimization of actuation parameters for each nasal spray and MDI product was performed using the SprayVIEW NSx/MDx automated actuators. The relative standard deviation (RSD) for six replicates measurements of impaction force varied from 2.1% to 6.6% for all tested products, indicating good repeatability for the method.
