The Nickel Level test, using an Atomic Absorption Spectrophotometer (AAS) with Flame and Graphite Furnace Atomization (GFA), is a precise method for determining nickel concentration in environmental or biological samples. This test is highly efficient in measuring nickel levels, helping assess potential exposure to this heavy metal. The test is used in a variety of applications, including public health monitoring in industrial areas, water testing, and occupational exposure assessment. Nickel is a common element in many industries, and excessive exposure can lead to serious health issues, such as allergies or toxicity. Due to the accuracy of the results, this test helps guide necessary interventions to protect both individuals and the environment.
