OECD, AHPA, ISO and ASTM Biodegradable Surfactant Phosphorus Content Estimation

URGENT MULTIPLE TESTING Analytical Chemistry Laboratory needed for the following OECD, AHPA, ISO and ASTM biodegradable surfactant testing: – ASTM D820-1993 (reapproved 2016) – Standard Test Methods for Chemical Analysis of Soaps Containing Synthetic Detergents – EPA 365.1, 365.2 AND 365.3 – Determination of Phosphorus by Semi-Automated Colorimetry; Phosphorous, All Forms (Colorimetric, Ascorbic Acid, Single AND Two Reagent) – ISO 6878: 2004 – Water quality – Determination of phosphorus – Ammonium molybdate spectrometric method – APHA 4500-P – Standard Methods for the Examination of Water and Wastewater. 2. Ultimate aerobic biodegradability – OECD 302 (Inherent Biodegradability) We would like to start testing asap. Thank you.
