Personal Air Samplers—a New Approach for Industrial Hygiene

The Aura personal air sampler from Restek (USA) is setting a new standard in sampling technology. This innovative passive sampling device is designed to meet OSHA and NIOSH requirements, while overcoming the limitations of sorbent tubes and badges. Notably, this quiet, robust sampler does not require a pump and manages variations in face velocity, temperature, and humidity better than traditional sampling approaches. Since this is a whole air sampling technique, it allows multiple analyses of >100 VOCs, providing broader application utility than analyte-specific sorbent techniques. The Aura personal air sampler has a wider effective range than tubes and badges—it is sensitive down to pptv levels and there is no risk of breakthrough even at ppmv levels. Comfortable to wear and easy to operate, this novel sampler features a simple, quick connection that starts and stops flow with no flow calibration required.
