with chloride determination and bromine interferes with bromide. Silica gel will collect ca. 30% of the free Cl. 2. and Br. 2. in an atmosphere [4]. Acetate, formate and propionate have elution times similar to F-and Cl . If these anions are present, use a weak eluent (e.g., 5 mM Na. 2. B. 4. O. 7) for greater resolution. OTHER METHODS:
