I am in agreement with the use of colorimetric tests
for this issue. The EPA regulations are generic at
best and lead to confusion in relation to waste

I also have a question for the group; Does
anyone know how to clean pyrex glassware when you are
using wax based samples. I am performing fatty acid
and paraffin content analysis on candle samples and I
am at a stand-still in relation to how to properly
clean soxlet, ehrlemeyer and pipette glassware once
the hot wax has been treated with either toluene or
methanol in preparation for future use. Any
suggestions would be greatly appreciated.
