Air Pollution Chemical Analysis: Why Upgrade to an Electronic Sampler?
Why should Luca update his manual air sampler to an electronic one?
Luca wants to identify and quantity the chemicals causing air pollution in a city, but he is using a manual air sampler to collect air samples.
Answer:
Manual samplers are prone to effects of temperature, speed of wind, and air concentrations.
Manual samplers face several challenges that can act as drawbacks to obtaining accurate results. They are subjected to effects of sampling duration where long sampling times are needed to obtain an adequate mass for detection. Manual samplers face challenges when measuring non-volatile species because particles are observed into the adsorption medium at a slower rate of diffusion.
