Interferences for electrochemical cell analyzers Abstract Industrial hygienists commonly use electrochemical analyzers to measure gaseous chemical contaminants in ambient air. These devices combine real-time measurement, precision and reliability. However, compounds other than those that are to be measured may introduce a positive or negative bias. Manufacturers generally provide a partial list of such interferents. Following anecdotal reports from end-users of inaccurate readings obtained using electrochemical analyzers, the authors studied the effects of contaminants likely to be present concomitantly with target compounds in different workplaces. The reported results supplement the list of interferents developed by manufacturers, helping users to better plan workplace evaluations and interpret the results when using electrochemical analyzers.
