  3. Problem Statement In order to simultaneously collect emissions and transport undisturbed casts for analysis, current hollow cast models will be combined with the existing side stream smoking machine. Device will operate using acquired data from the wPSMD. Unit needs to be self-contained, portable, fit on a workbench, and user friendly. The unit must also be production ready for identical machines in other labs. During operation smoke needs to be ventilated responsibly and the unit must be interfaced with LabVIEW.
