Sample & Sonic Mixero Sonic Emulsification of the Water
Fuel Sample (Patent Pending).
o Sonic mixing ensures consistent water droplet size by its ability apply reproducible amounts of energy to the sample.
o Water Droplet size has a direct effect on the performance of filter materials 1.
o Mixing probe consists of 40 KHz resonate ceramic drive with custom designed matched acoustic horn.

Frequently Asked Questions
Do you intend to seek equivalence under the current ASTM Method? Yes
Will you also address the DSEP Method? Yes, we have just started testing.
What are the expendables used? The filter, plastic beaker, and solvent (3 ml Isopropyl Alcohol).
What is the expected cost/test? This has not been fully established, however, we anticipate that it will be lower than the current method.
Commercial Timing? Dependent on the EI and ASTM method development time.
