The machine works by 1/setting desired wavelength 2/inserting a distilled water sample 3/zeroing a and 100% T (1 button push) 4/inserting solution (cs) into sample chamber 5/observing digital reading for A or T I do not have continuing access to this machine,otherwise I would run a selection of batches with differing production times to get a varied range of cs concentrations,and compare the results. Anyway,thank you for your replies pete

Atomic absorption spectrophotometry is another animal alltogether. Peter, did you run a control sample of plain distilled water with which to compare? A quick visual scan of your data suggests a basically smooth, gradual rise in transmissivity with increasing wavelength. The data points are so sparse there's no chance to discern any fine structure. I think there was some more informative work done using a scanning UV/visible/IR spectrophotometer, but I don't remember by whom. With a continuously variable wavelength light source, one could expect to see an actual resonant peak (or trough) where the particle size distribution would interact with the wavelength of the light. A sufficiently small particle size would interact in the ultraviolet, I believe. I don't know what, if anything, you could see of the ionic component of your preparation. I hope others remember more about this than I do and can dredge up some references and/or archived messages on the topic. Be well, Mike D.
