This PT sample is a concentrate for dilution in DI water.
The solvent for this sample is NaCl.
The sample must be stored at room temperature.
Partially fill a 1000 mL volumetric flask with reagent-grade water.
Open vial PE1091-1.2G and weigh 500 mg of solids and quantitatively transfer to the volumetric flask using a glass funnel.
Fill the volumetric flask to volume (1000 mL) and mix by inverting the flask 10 times.
Let the flask stand for 10 min and invert again 10 times.
The sample is now ready for immediate analysis.
Do not filter the sample prior to volatile analysis. Analyte losses may occur.
