This poster on stack particle size analysis by microscopy was presented at the Source Evaluation Society (SES) Conference. I thought it would be beneficial to share it with you.
Scanning electron microscopy for stack particle size measurement is useful where stack geometry, cyclonic flow or moisture preclude the use of Method 201A, and when the stacks are simply too clean to use gravimetric methods. One of the most common questions that we get from prospects is “Do regulatory agencies accept results from microscopy particle size measurement?” Our clients have submitted microscopy particle sizing data to state agencies, and many states have accepted them.
In addition, we will help our clients address any questions from regulatory agencies regarding microscopy particle size analysis methods, data accuracy and robustness of the measurements.
If your facility or clients encounter situations where 201A is not appropriate, we will be happy to assist.
