TABLE II.
Size distribution of the nebulized mist of the peptide solution using an NGI.
| Stage | % of total mass (%) | D50a (μm) at 15 l/min |
|---|---|---|
| Induction port + 1 | 7.14 | ≥14.1 |
| 2 | 0.96 | 8.61 |
| 3 | 0.93 | 5.39 |
| 4 | 12.51 | 3.3 |
| 5 | 24.37 | 2.08 |
| 6 | 17.17 | 1.36 |
| 7 | 15.62 | 0.98 |
| Micro-orifice collector (MOC) | 20.91 | <0.98 |
a
D50 means cut diameter size. It is calculated for each stage. It is the particle diameter for which the efficiency and the penetration are 50% or where half these size particles are captured and half penetrate the collector.
