The response time of the electrochemical cell was investigated. An average response time of about three seconds was obtained with a new cell. The cell was made with a methyl cellulose gel that was prepared with an oxime solution. The response was measured with a cyanide generator delivering about two micrograms per liter of HCN. The sensitivity was about the same as that of the standard oxime cells. A response time of about six seconds was measured with the thin film cell but evaporation of the electrolyte was a serious problem with this cell. Drying of the gel will be a problem with the field use of the new cell, but we should be able to design a cell to keep the proper amount of water in the gel.
