Since a [AA} spectrophotometer essentially vaporizes a sample into a
plasma, why would particle size be any part of that?

Dear csers,
I recently had the opportunity to play with a spectrophotometer.Using the
instruction book procedures gave the following readings:
I took readings at wavelengths for
blue(470nm),green(555nm),yellow(585nm),orange(610nm) and red(650nm).The
results indicated a figure for Absorption(A) and Transmission(T) %.
Blue;A=0.143 T=71.8
,Green;A=0.136 T=73.2
Yellow;A=0.118 T=75.9
Orange;A=0.115 T=76.8
Red;A=0.093 T=80.7
My question for those familiar with this apparatus is;
What particle size could be ascertained from these results?
My cs production method uses 27v and halts at 8mA using spiral shaped
electrodes spaced 25mm apart.Results are a clear solution (no colour) but
a slight tyndall effect observable via high power(1w) leds
Thank you for taking time to reply.
