Pesticides Analysis of 1,2-ethylene dibromide (EDB) and 1,2-dibromo-3-chloropropane (DMCP) by (Agilent 6890 Micro-ECDs) after microextraction with hexane in acc ordance with U.S. EPA method 504.
Relative standard deviation (% RSD) for the entire method was less than 7% over a concentration range greater than two orders of magnitude with method detection limits of 0.003 ug/L or lower. So Nice!
