1. A handheld sampling tool comprising:
- an inlet tube configured to deliver a quantity of rinse solution from a rinse solution source to a surface being sampled, said inlet tube having a valve configured to control flow of a liquid through said inlet tube, said inlet tube connected to a sampling head configured to disperse said rinse solution through a nozzle over a sampling surface;
an evacuation tube configured to connect with a source of vacuum pressure to evacuate said rinse solution from said sampling surface, said evacuation tube connected to an outlet of said sampling head, and an outer flexible retaining skirt configured to define a sampling chamber and to hold said rinse solution therein, said outer flexible retaining skirt defining plurality of air flow apertures configured to provide desired levels of air flow and turbulence within said sampling chamber so as to assist in recovering desired materials from said sampling surface.
