[Stoves] TESTING: Fine Particulates from a Selection of Cookstoves

[Frank Shields]

Dear Stovers,

There are so many variables along the path to the filter paper used when testing particles that I would think all values in suspect. Any small errors in values of dilution, flow and temperature will accumulate to large errors. 

A better way is to measure Helium after the filter. Introduce Helium at a rate of one liter per minute into the stove and then determine the amount of particle buildup on the paper (ug) / sum of liter Helium recorded from after the filter. You know ug particles per liter Helium and Helium is being introduced at one liter per minute.  This without the need to know all the dilutions, flow rate etc etc.  

I wonder if this would actually work.

Regards

Frank
