Indirect determination of nitroglycerine by biamperometric titrimetry

A procedure is described for the determination of nitroglycerine in propellant samples by biamperometric titrimetry. The method is simple, avoids the use of expensive instruments, and is free from interferences other than those occurring in the classical techniques. The accuracy and precision are equal to those of existing methods. The reduction and titration steps are performed in the specially designed flask.
