In order that the test materials he properly representative of current American practice, we are requesting that you provide the following data on (a) your current industrial product, and, (b) a ''highest purity" product you would be willing to provide in tonnage quantities to a guaranteed analysis specification.. Reguested Data 1. Production process (identi fied by appropriate patent reference or commercial process description) 2. Raw material source, i.e., acetylene from calcium carbide, from hydrocarbon cracking, etc, 3, Assay: Minimum___ % Typical % Maximum % 4, Identified impurities: Minimum Typical Maximum a b. c. etc. ppm ppm PPm ppm PPm ppm For each item under question (4) please identify method of analysis and limits of detection. A copy of the list of the im purities reported as being in material used in an earlier Euro pean study is attached for your information.
