Two different instruments, both working over the size range 1.4-25 pm. were used, aCoulter Counter and an instrument based on the principleof forwardscatteringoflaserlight.Theformof sizedistributionobtainedwithbotbinstrumentswasverysimilar

This behaviour is similar to thatfound for systems of higher solubility but raises important questions concerning the reasons for such effects.
