| Abstract |
In the study each participant was shipped three sterilized water samples in disposable 1-quart polyethylene containers. Sample 1 was composed of filtered river water containing 2.94 mg/liter linear alkylsulfonates (LAS). Sample 2 was tap water containing 0.48 mg/liter LAS. Sample 3 was distilled water containing 0.27 mg/liter LAS. A small amount of methylene blue and a copy of the procedure were sent with the samples. The data indicate no difference in methylene blue obtained from many different suppliers. Results from 111 analysts show good accuracy and precision for all samples. |
