CONTROLLED-POTENTIAL AND DERIVATIVE POLAROGRAPH Q-1988A (Engineering Materials)
This package contains 5 drawings and 16 specifications. The polarograph, Q-1988-A, is a refinement of B-1988. They are both controlled- potential d-c polarographs. It is used for high-sensitivity polarography both regular and derivative. In the modified polarograph, the polarizing unit has electronic scan and linear residual current compensation. The output of the electronic scan circuit is stable enough for derivative polarography at high sensitivity and has less noise than does the output of the electromechanical system used in Q-1988. The performance of the electronic scan circuit is superior to that of a conventional motordriven multiturn potentiometer scanner. Derivative polarograms can be measured down to micromolar concentrations. With a stable drawn out capillary, the detection limit can be extended to at least 10/ sup -7/ molar. (F.S.)
