制备说明

Description

• This PT sample is a concentrate for dilution in DI water.
• The sample must be stored at room temperature.

Sample Preparation

• Partially fill a 1000 mL volumetric flask with reagent-grade water.
• Open vial PE1282-1.2G and weigh 500 mg of solids and quantitatively transfer to the volumetric flask using a glass funnel.
• Rinse the flask with reagent-grade water.
• 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.
• "Fixed Solids" refers to the portion of the sample remaining after the ashing process (550 ?C). "Volatile Residue" refers to the amount of sample lost during the ashing process (550 ?C).
