A precision drop-fall detector for polarographic and electrocapillary work.
This paper describes the construction of a rugged yet very precise detector for use in polarographic and electrocapillary work. It employs an a.c. bridge technique to utilize the large and abrupt change in capacitance on drop-detachment. Timing and recording of drop-times is achieved with a laboratory microcomputer or a counter/timer.
