Solvents used to prepare mobile phases

The following lists the most common ingredients used to prepare mobile
phases for reverse-phase LC/MS (API):
• Water
• Methanol
• Acetonitrile
• Formic acid (<0.1%)
• Acetic acid (<0.1%)
• Trifluoroacetic acid (<0.1%)
• Ammonium acetate (<10 mM)
• Ammonium formate (<10 mM)
These solvents are not expected to cause any problems with the materials
appearing in the table on page C-2.
