Greetings, I have perfomed DLS of my xerogels but the pdi >1 , between 1.2-2 and standard deviation is very large (300-700) . Can I interpret my result with this data or I should repeat.
How did you make your xerogels? Can you provide a reference to the procedure you used and anything else you can provide to explain why you believe the size distribution should be narrower?
@john Francis Miller, Sir I wanted to synthesize 3D hydrogels of Polyanilline. But ended up with xerogels. In one beaker I took aniline and phytic acid and in another beaker the oxidant. After attaining 0'C temprature, mixed them thoroughly.
How can describe my sample size since the variation is very large. ? Even If I took an average, in some samples there is standard deviation of 1000.
