This is my orientation, others on the list may see it otherwise. It is necessary to standardize a protocol, then duplicate the procedure each time you make a production run. Take a representative sample and send it off to a lab to be tested for ppm (and particle size if you really want to get fancy). Then stick to the exact procedure in the future. It is aproximate, but close enough I think, for personal use. > How does one filter them out? > Lab supply houses have different types of filter paper. I use 25micron, 5micron, and 1micron filters. About 6-10 cents a piece. VWR has a good selection you can get a catalog from them or order over the phone 1-800-923-5000. I'll send you some materials via private e-mail, they are kind of bulky. Good Luck and God Bless, Scott ############################################################################### John 1:1- "In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father, full of grace and truth."
