Determination of nitroaromatics and higher-boiling halogenated compounds in water

GC measurement with double ECD on two capillary columns of different polarity Equipment 

GC with capillary columns, integrator or recorder Water, e.g. from a Millipore superpure water system Nanograde toluene Standard solutions  

Nitroaromatics, approx. 0.1 - 6 pg/ml in nanograde acetone (Table A) Higher-boiling halogenated compounds, approx. 0.5-15 pg/ml in nanograde acetone (Table B) 

Internal standard solution 1,1,2,2-tetrabromomethane, approx. 1 pg/ml in nanograde acetone
