In the second part of the study, we looked at roller compactor containment. Again, we conducted the same type of studies with the material, but now we have an excipient with the API. The roller compactor process is more complicated than dispensing, so our numbers are a little higher, which makes sense. We're still dealing with the same hazard, but the process has changed. Even with that, the containment levels are still below 20 nanograms per cubic meter in the roller compactor process.
