Lavinia, I recently talked to equi-analytical (gal who answered the phone), I asked what the difference was between #601 and #603 besides results for lignin, fat, and ash were included in #601. She told me they used 2 processes in #603 but the results in both #601 and #603 were identical. I asked about the price difference, she said #603 cost more because 2 processes were used. The results were always the same in each. Was she wrong?
