After completion of this course, learners will be able to calibrate and operate laboratory air sampling devices. Course structure is as follows:
• Lecture: Generation of test atmospheres of gaseous pollutants; Effects of variables on atmospheric sampling; Selection of sampling train components; Air quality surveillance networks and their siting; and Concepts and procedures for ensuring quality in atmospheric sampling
• Particulate Laboratory: High volume sampler and orifice calibration; Performance audit of reference flow device; and Use of constant flow controllers
• Flow Laboratory: Calibration of flow devices including wet test meters, limiting orifices, rotameters, and mass flow meters; Preparation of dynamic calibration gas via a dilution system; Controlled Test Atmosphere Laboratory; Preparation of dynamic calibration gas via a permeation system coupled with a dilution system calibration of continuous monitors using these calibration gases; Calibration of a particulate matter (PM2.5) sampler; and Internal and external leak checks, calibrate temperature sensor, pressure sensor, and flow rate system
