Instructions for Use:

Before opening, each ampoule should be equilibrated to room temperature and the contents thoroughly mixed. Before use, the ampoule should be opened immediately in a pre rated market. CRM solutions should use calibrated equipment for transfer to ensure accuracy. The certification value can only be guaranteed if a sample is taken immediately after opening the ampoule to limit solvent evaporation.
