M 42] [P 39] In a slit-type interdigital micro mixer, first mufti-lamination patterns are created [20,124], Then, the multi-laminated stream is introduced into a chamber of larger cross-section. A jet is formed and induces two eddies in the dead zones adjacent to the initial channel (see Figure 1.97). Mixing is not completed within the chamber, as evidenced by the non-uniform color distribution. The contribution of the jet mixing to the total mixing is unclear. 

To minimize the particle bounce off effect, collection surfaces should also be selected carefully. Common types of impaction surfaces include membrane, fiberglass, silver membrane, Teflon and Nuclepore filter, and brass and stainless steel shim stock. Table 2.2 shows an example of the effect of selection of collection surface on the wall losses (Newton et al., 1990). In Table 2.2, the test aerosols are droplets of 1% CsCl plus 1% uranine. Three types of cascade impactors were used, including Mercer, Sierra Radial Slit Jet (SRSJ), and Lovelace Multi-Jet (LMJ). The occurrence of particle bouncing may be indicated by the presence of excess mass on the back-up filter.
