Noise Dosimeters & Sound Level Meters

In Vitro − In Vivo Correlation (IVIVC), as defined by the FDA, is a predictive mathematical model describing the relationship between the in vitro property of a dosage form and relevant in vivo response. The FDA has provided little to no guidance on IVIVC practices, but there is growing interest including an FDA draft guidance using IVIVC methods for a generic drug development.

A basic system is comprised of two more-realistic elements to give a more accurate representation of how a drug may behave in a specific type of patient’s respiratory system: the first is a more anatomically representative mouth and throat feature, and the second is a more representative breathing pattern.

TSI’s suite of cascade impactors can collect particles with aerodynamic diameters (cutpoints) from 10 nm to 10 µm, in 3 to 13 different size fractions, and at flow rates of 2, 10, 30 or 100 L/min. The number of stages determines the size resolution of the collected samples, and consequently determines the level of detail of the data generated from the quantitative analysis of these collected samples. MOUDI II impactors have rotating stages. When the stage is rotated relative to the nozzle plate, the impacted particles are deposited in a more uniform manner across the impaction surface. This increases the amount of particle mass that can be collected, reduces the probability of particle bounce and re-entrainment, and optimizes quantitative analysis of the collected samples.
