Listen to the brothers said that the autosampler vials should be soaked in acetonitrile. When used, it should be soaked with methanol and ultrapure water. Must it be like this? What are the special requirements for the preservation of the autosampler vials?
In fact, there is no difference between the washing requirements of ordinary glass instruments, but the 2ml autosampler vials mouth is small, it is not easy to use the brush to reach in the brush, so it is generally soaked in the washing solvent (usually washing the refined water) ultrasonically, then Wash in clean water, rinse with ionized water, and dry. If you can't wash things, wash them with ethanol!
This is the end of the introduction of What is the storage method of the autosampler vials?. I hope it can help you.
