The monitor, developed and marketed by Solid State Sensor Company, Lisle, Illinois, depended on molecular diffusion of the analyte to the collection medium. The samples were stored for up to 2 weeks before analysis. Samples were thermally desorbed and analyzed by infrared spectrophotometry. Field samples were collected in hospitals and dental offices. In the laboratory and field tests, the monitors over sampled for short exposure times and under sampled for long exposure times. None of the results were affected by humidity changes. The authors conclude that the performance of the monitor is unsatisfactory. 收起
