Seems like there are spectrophotometer that use reagents that work and there are spectrophotometer that use reagents that did not work. It has been said that James Holmes and Robert L. Berger each have spectrophotometers, and that is one of only two methods of correctly measuring ppm (ug/ml). (The other is with an I.S.E.(ion specific electrode) which Ivan has). Why would James and Roberts spectrophotometers, work and the Hanna HI 93737 Silver Meter not work?
