OTCR Cadmium Coil Common Sizes

Getting the Correct OTCR Cadmium Coil for Your Flow Analyzer In our cadmium coil blog series, we wanted to address the difference between our 12 inch and 24 inch OTCR (Open Tubular Cadmium Reaction) cadmium coils. The 12-inch coil was originally designed to be used on RFA instruments that used a slower pump speed and [...]

Metal Contamination Reduces Cadmium Coil Efficiency

Last week, we discussed the loss of reduction efficiency in cadmium coils caused by nitrate contamination in ammonium chloride. This week we are examining metal contamination and cadmium coil efficiency. This type of contamination occurs in the sulfanilamide solution. Of course, sulfanilamide solution contains N-naphthylethylenediamine dihydrochloride which serves to bind heavy metals. If metal exists [...]
