    LC-MS Solvents and Reagents

    New LC-MS systems have raised the bar on the purity expectations of chemicals used for sample preparation, mobile phases and post-column additives. Alkali ions, plasticizers and surfactants interfere strongly with LC-MS by causing higher background noise and the formation of adducts. Sigma-Aldrich h...
