Photothermal Deflection Spectroscopy of Collected Aerosols

Considerations for Chemical Analysis Trace analysis needs low detection limits Dynamic range is important for practical samples Precision is equally important in mixtures Analysis should be standardized Measurements and reports should be comparable between all laboratories Need for stable calibration methods and materials Suitable instrument calibration standards are needed for each phase andexperiment type Standard Reference Materials (SRM) seem to be lacking in the analyticalchemical community using photothermal spectroscopy
