We used to wash with water first, ultrasonic, and then change with ethanol. In the super god, rinse with ethanol, and finally rinse with ultrapure water, LC-MS vials dry it. I also heard that some units are washed with chromic acid wash.

Put a surfactant, wash the water, then ultrasound for at least 30min. Then take out the tap water and wash it three times, and wash it twice with pure water.

Here are two issues to be aware of: one is a small bottle, you must pour off the sample, and you will lose it. Then put the washing water into it! Sometimes the vial is thrown into the water, with a bubble floating inside, and there is air inside. This is the same as no ultrasound. The other is what your experimental sample is so soluble. Some experimental samples are insoluble in water and are easily soluble in organic solvents. Then the washing spirit can not be cleaned, and this situation can be washed with ethanol.

When I was experimenting at school, the teacher said that the bottle lid and the mat should be ultrasonically separated. After I was lazy after work, I didn’t do it. In fact, it can be washed together with ultrasound.

Then dry the temperature,LC-MS vials do not be too high, preferably 40 ° C, or 60 ° C is enough.
