"We're pleased with the Solids Standards. We've used them with batches of total and volatile solids. My analyst is coming up with numbers very close to yours. I don't think we've varied more than 6% from your target values on any of the ones we've completed so far. I was surprised that the volatiles were coming out so well. I expected more variation."
