Measurement of chloride in sweat by use of a selective electrode and strip-chart recorder.
We describe a method for direct potentiometric measurement of sweat chloride by use of a chloride-selective electrode, with strip-chart recording of the measurement to facilitate interpretation of the measurement. Comparison of this method and the Gibson and Cooke method [Pediatrics 23, 545 (1959)] gave a correlation coefficient of 0.86. Recording of the same test at various pressures showed that different pressures had little effect if they were kept constant.
