I. INTRODUCTION
This System Evaluation Matrix #1 is intended for use as a
reproducible background signal in the evaluation of LC and MS
system performance.
It is especially suitable for standard small molecule applications
where a complicated matrix is required, but naturally occurring
alternatives, such as urine and plasma, are impractical.
Typically additional application-specific components are added to
the matrix to provide analytical markers, although it may be used
without these.
The matrix provides a background in both positive and negative ion.
II. Storage and Stability.
The lyophilized powder is shipped at ambient temperatures, in
Waters TruView™ Max Recovery Vials (P/N 186005668cv). The
prepared matrix is stable for at least one week. Beyond this time
for performance testing and evaluation, fresh re-preparation of the
matrix is recommended.

III. Reconstitution of the System Evaluation Matrix #1
1. The vial contains 33.33 mg of lyophilized matrix. Add 1 mL of
water to the vial to make a concentration of 33.33 mg/mL.
2. Recap and then agitate the vial contents (e.g. via vortexing or
ultrasonic bath), to ensure the lyophilized powder dissolves.
3. For use on SYNAPT® G2-S and detectors of similar sensitivity
dilute 1:20 in water.
IV. Use with an Analytical Standard
The matrix provides an abundance of peaks. By adding an analytical
standard the matrix can be used as a background.
Waters Analgesic Mix (P/N 186006350) can be added to provide
a collection of small molecules suitable for metabolomics method
development. Refer to note 6 in section VII.
• Prepare a 200 ng/µL stock by adding 1 mL acetonitrile to the
Analgesic mix vial.
• Prepare 50 ng/µL working concentration by taking 25 µL of the
stock and diluting with 75 µL of water.
• Add 5 µL of 50 ng/µL Analgesic Mix to 495 µL of the matrix to
make a final concentration of 0.5 ng/µL.
V. Example of Using the System Evaluation Matrix #1 and
Data Aquisition
Figure 1 shows a representative chromatogram of the control matrix
diluted 1:20 on a SYNAPT G2-S.
