This post was last edited by Zaihui Kangqiao on 2016-5-18 at 08:32. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" activity can be viewed directly, and the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! You get 3 wealth points just for participating, and an additional 4 wealth points if you answer correctly~~~ Short answer: When taking water samples for chemical analysis, what must be used to clean the sampling bottle? sample water
For chemical water sample testing, it is necessary to rinse the sampling bottle thoroughly with the sample water
Rinse the sampling bottle repeatedly with the sample water (at least 3 times), and then take the sample.
