Over the past 15 years, open path monitoring has come on in leaps and bounds, yet many of the systems that are based on open path technology are still fighting against negative perceptions from potential buyers. So how does traditional 'point method' analysis compare with open path? The traditional point method technique generally requires a different analyser for each gas be measured. For example, if you were measuring for SO_2, NO_2 and benzene, you'd need one point analyser for each. Calibration for point method analysers needs to take place approximately every two weeks - or even more frequently. These traditional analysers can only measure the 'gas of interest' (air in a close proximity) and therefore, in some cases, may not give a truly representative measurement.
