Chromium (Cr) level analysis by Atomic Absorption Spectrophotometer in Flame and GFA mode is an advanced analytical test aimed at measuring the concentration of chromium in environmental or industrial samples. The analysis is based on atomic absorption technology, which allows for highly accurate determination of metal element levels. Flame mode is used for measuring high concentrations, while graphite furnace (GFA) mode is employed for low concentrations. This test provides reliable and effective results for monitoring pollution and determining chromium levels in water, soil, or various products.
