PROCEDURE
The lockmass solution is leucine enkephalin (LeuEnk) prepared at a concentration of 200 pg/μl.
- Prepare a stock at 1 mg/mL (μg/μL) of LeuEnk solution by adding 3 ml of water to the Waters reference standard #186006013. Do not use organic solvent, because the leucine enkephalin will not dissolve.
- Add 100 μL of the LeuEnk stock solution to 500 mL of 50:50 water/acetonitrile + 0.1% formic acid.
