C18 Column Check

The Quality Control Reference Materials portfolio is a unique collection of standards and mixtures. These products allow the user to evaluate and benchmark their chromatography system before analysis of critical material. The products in the portfolio are all specially formulated based on the expertise of Waters scientist. The Reversed-Phase QCRM is a significantly complex reference material mixture in that it contains compounds which could be challenging to separate. It is designed to provide this complexity and is appropriate when complex assays are routinely performed. It can be used with a variety of column chemistries and dimensions, and system hardware.

The Reversed-Phase QCRM contains 7 compounds including uracil, butyl paraben, naphthalene, propranolol, dipropylphthalate, acenaphthene, and amitriptyline at pH 7.
This standard mix should be used to confirm the benchmark performance of your analytical HPLC or UPLC system. This particular QCRM is a specially formulated mix that includes a void marker, neutral, acidic and basic compounds. These compounds were vigorously tested and evaluated and chosen because they provide the following advantages:

• Excellent benchmark
• Good peak shape on UV
• Acceptable for use on a variety of column
