Description

• Ideal high purity mobile phase blend for LC/MS and UHPLC-UV applications
• Pre-mixed for ease-of-use
• Low metal ion content to ensure minimal metal contamination
• Formic acid (FA) is a common mobile phase additive that provides protons for LC/MS analysis
• FA is also known to improve the peak shapes of the resulting separation
