Preparation Note

This PT sample is packaged as a 20mL concentrate.
The solvent for this sample is 5% nitric acid by volume in DI water. This also acts as the preservative

Sample Preparation

Partially fill a 1000mL volumetric flask with reagent-grade water (near 20ºC) and add 1mL of trace-metal-grade nitric acid.
Open ampule PE1205-20ML (be careful to avoid cuts on glass) and transfer 10.0mL of concentrate to the volumetric flask.
Fill the flask to volume with reagent-grade water and mix well.
The sample is now ready for immediate analysis.
A reagent-grade blank should be analyzed concurrently for background correction. the water blank should be made to match the acid matrix of the standards and samples.
NOTE: The 0.15% v/v nitric acid specification is a minimum; the amount and type of acid may be altered to routine analytical procedures if needed.
NOTE: Mercury is present as inorganic mercury.
