Introduction

Atomic Absorption (AA) still remains a frequently used method for elemental analysis in both aqueous and organic media. Graphite furnace atomization (GPAA) and hydride generation techniques provide the best detection limits for many elements, especially those of environmental concern. For the determination of minor and trace chemical elements in various chemical and metallurgical products, in drinking water and wastewater, in soils and biological samples, atomic absorption spectroscopy is the preferred method in most analytical laboratories.

SPEX CertiPrep offers a selection of atomic absorption calibration standards and matrix modifiers. As always, we supply each solution with a comprehensive Certificate of Analysis which documents the quality. Each standard is manufactured under the same Triple-Checked Quality Assurance Program as our plasma-grade solutions:

SPEX CertiPrep's unique Triple Checked for Quality® just got better. We now triple check our products for quality twice.

The Starting Material

• Stoichiometry of starting material
• Trace cation/anion standard impurities by ICP-AES or ICP-MS or IC
• CL, SO4, checked by classical wet chemistry

The Final Solution

• ICP-AES or IC for the major element
• Classical wet assay for major element
• Final ICP-AES or ICP-MS or IC analysis for trace cation/anion impurities on the actual solution

To ensure that your measurements are accurate, you can rely on our certificates to provide complete information.
