Abstract: Methods were developed for determining nitroguanidine in soil and water. The soil method involves extracting a 2-g sample with water using an ultrasonic bath. Soil extracts and water samples are filtered through a 45-~membrane prior to determination by RP-HPLC. Separations are achieved on a mixed-mode RP18/cation column eluted with 1.5 mL/min of water; detection is by UV (~ = 263 nm). Certified reporting limits were estimated at 5.0 ~g/L for water and 0.5 ~g/L for soil. Note: Certain scientific symbols could not be rendered by the character set available to this program, a ~ has been inserted to indicated missing symbols. The file contains the symbols in question.
