This Agilent matrix modifier solution contains 10 percent ammonium phosphate NH4H2PO4 in a 100 mL volume, formulated specifically for graphite furnace atomic absorption GFAA analysis. Optimized for use as a matrix modifier, it stabilizes volatile analytes during high-temperature atomization, thereby enhancing the accuracy and repeatability of trace metal determinations in challenging sample matrices. This reagent is particularly effective for analysis involving elements susceptible to chemical interference, such as lead, cadmium, or arsenic, and is commonly used in environmental, food safety, clinical, and industrial testing laboratories. Its high purity and lot-to-lot consistency support routine calibration and quality control, ensuring reliable analytical performance.

Designed for seamless integration with Agilent atomic absorption spectrometers equipped for graphite furnace techniques, this modifier improves background correction and enables robust quantitation even in complex sample solutions. It is compatible with commonly utilized Agilent GFAA autosamplers, accessories, and sample preparation protocols. For laboratories conducting multi-elemental trace analysis, this solution complements Agilent graphite tubes, cups, and related consumables. Use in accordance with established Agilent GFAA protocols to maximize sensitivity and reduce matrix-related interference for precise results across a wide range of sample types.
