Preparation Note

This PT sample is packaged as a 1.5 mL concentrate.
The solvent for this sample is acetone.
The PT sample is not preserved.
The sample must be stored at 4 °C.

Sample preparation
Fill a 1000 mL Class A Volumetric Flask with 950 mL of organic free reagent water.
Allow the ampule concentrate to equilibrate to room temperature.
Open the ampule PEO-410 and pipet exactly 1.0 mL of the concentrate into the flask.
Bring the flask to volume with reagent water.
Stopper the flask and mix well.
This represents the sample for analysis.

Matrix Modifier
MMW-001 is intended to modify the products to simulate a waste water sample.
The final dilution will replace the use of DI (Reagent Grade) water for the prepartion of the appropriate CRM/QC sample.
The sample will add turbidity and TSS to the final volume. These do not affect the properties of the analytes of interest in the final sample if prepared according to instructions.
Note filtration may be necessary as required by your method.
To use the matrix modifier simply mix Waste Water Matrix Modifier as specified in the MMW-001 instructions. Use this solution in place of the reagent grade water in the instructions above.
