ENVIRONMENT

• UHPLC
• Column care and use
• Storage conditions
• AccQ•Tag Ultra C18

ANSWER

Short-term storage (up to 4 days): 50/50 AccQ•Tag Ultra Eluent A/ AccQ•Tag Ultra Eluent B OR ACN/water if running a Binary Solvent Manager (BSM).

If running on a Quaternary Solvent Manager (QSM): 25/25/25/25 A line/B line/C line/D line

Column should have flow rate on at least 0.2 mL/min if sitting unused for less than 4 days; all lines should be moving with solvent flushing through them.

Long-term storage (>4 days): Flush column with water for 30 minutes at 1.5mL/min. Follow with 100% acetonitrile for 35 minutes at 1.5mL/min and store at room temperature.
