Modifications to the Briggs Micro-Electrophoretic Cell and Comparisons with the Zeta-Meter Cell R. M. ROCK, Research Associate Department of Environmental and Sanitary Engineering Washington University St. Louis, Missouri N. C. BURBANK, Professor of Environmental Health and Sanitary Engineering University of Hawaii Honolulu, Hawaii INTRODUCTION A growing interest in applications of micro-electrophoresis (hereafter referred to as "MEP") to the treatment of industrial waters and wastes has led an increasing number of research and operations personnel to investigate the possibility of installing apparatus for these determinations in their laboratories. Many have soon discovered a frustrating lack of complete, detailed information available on descriptions of the design, fabrication, and operation of such equipment. Four basic configurations are presently in use today: the Mattson circular cell (1), currently employed in studies by Packham (2); the Northrup-Kunitz flat cell, supplied by A. H. Thomas Co. (3), and recently employed by Bull (4); the Briggs flat cell (5), made popular in extensive coagulation studies by Pilipovich (6) and Black (7, 8), and the Zeta-Meter circular cell reported by Riddick (9, 10). Publications by Black and Riddick have been extremely helpful in providing descriptions of the Briggs and Zeta-Meter cells and have as a result of their studies rendered these configurations two of the most popular and widely discussed units in the U.S. today. Even so, a great deal of additional information has yet to be published on certain details and particularly comparisons of these units, for those who approach the task of making a selection between them with only sparse knowledge beforehand. It was the purpose of this study to take the original design of Briggs, to improve upon it in any way that aided the speed of determinations and the versatility of applications, and to compare the resulting configuration to the patented, manufactured cell known as the Zeta-Meter. MODIFIED BRIGGS CELL The original design of Briggs is represented in Figure 1. It is characterized by an all-glass design, good for aqueous as well as organic media, and by the capability of being fabricated from relatively inexpensive standard laboratory stock items. Many details of the cell have been described by Briggs and Black and do not bear repetition here. However, a few features are worthy of note insofar as they were considered by the authors as deserving of improvement or modification. - 589
