Phosphoric Acid Matrices

Phosphoric acid (H3PO4) is not commonly used in preparations since it attacks glass, quartz, porcelain, and Pt containers at elevated temperatures (greater than 100 °C). However, the presence of 3PO4 will not adversely effect any of the elements at low µg/mL levels and below.

If your matrix is not listed above, consult our Interactive Periodic Table or contact us for assistance.
