What quality should my used solvents have?

All used solvents should be of the highest quality. HPLC grade or MS grade solvents are suitable because they do not contain impurities that might lead to contamination peaks. Make sure that the used water for mobile phases is also of highest purity. It should be additionally purified and not only deionized.
