DATA QUALITY
002106
Reliability: Kiimisch ranking 2. Testing meets criteria for quality testing. However, the seed source was not indicated. There is a lack of characterizationofsample purity and the study lacks analytical confirmation of the amountoffiuorochemical proportion in the test solutions.
