These samplers do not require pumps, batteries, or specialized field equipment. They can be clipped near the breathing zone for personal exposure monitoring or placed in a strategic indoor location to evaluate area concentrations.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis product is especially useful for measuring \u003c\/span\u003e\u003ca href=\"https:\/\/airbyccsquared.com\/pages\/nitrogen-dioxide-in-indoor-air\" title=\"Nitrogen dioxide in indoor air\"\u003e\u003cspan\u003enitrogen dioxide in indoor air\u003c\/span\u003e\u003c\/a\u003e\u003cspan\u003e. Nitrogen dioxide is an important indoor air pollutant that can be produced by combustion sources such as gas stoves, furnaces, boilers, fireplaces, vehicle exhaust intrusion, and other fuel-burning equipment. Measuring nitrogen dioxide can help identify whether combustion-related pollutants are accumulating indoors and whether ventilation or source-control improvements are needed.

Exposure time can range from 15 minutes to 7 days, depending on the expected concentration and the purpose of the measurement. Care should be taken not to saturate the sensor. The maximum mass of formic acid that can be absorbed is reported to be 800 microg, so 50 ppm formic acid for 8 hours should be considered the upper practical limit for this sampler. Similarly, the maximum mass of acetic acid that can be absorbed is 500 microg, so 25 ppm acetic acid is the maximum concentration you should plan to sample.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eLonger sampling times, up to 7 days, are intended for indoor air quality measurements where organic acids are present at ppb levels rather than being directly used in the space.
