Excellent Idea!

For the group inaugurating the effort to commercially test CS, I would
like to offer a suggestion for your consideration.  If the person
generating the sample material would make up a 32 ounce Master Sample, a
very useful protocol might be invoked.  To wit:  By retaining the bulk
of this Master Sample, this person could ship small calibration samples
(together with a simple nomogram displaying actual test results) to each
of the persons who contributed to having the commercial test made.  Each
recipient would then have an excellent means of calibrating his/her TDS
instrument---individually.  This could help maximize the benefit of the
test for each of the supporters.  Best wishes to all.
