HILIC Quality Control Reference Material

II. STORAGE AND STABILITY

The standard mix comes in a Waters crimp top vial for direct injection and contains 1 mL total in 90:10 acetonitrile:100 mM ammonium
formate pH 3.0 buffer.

The standard mix is shipped at ambient temperatures. It is highly recommended that, upon receipt, the standard should be refrigerated at
4 °C for short term storage and for long term storage frozen.
