Description
Atomfair AFS Defoamer 372 – Product Information
Product Overview
Atomfair AFS Defoamer 372 is a high-performance defoaming agent specifically designed for atomic fluorescence spectrometry (AFS) testing of inorganic arsenic. It effectively eliminates and suppresses foam during the testing process without inhibiting the arsenic signal, ensuring the smooth progress of the arsenic hydride reaction and achieving stable and reliable test results. As an optimal alternative to n-octanol defoamers, it offers superior performance and practicality in analytical testing scenarios.
Core Performance Advantages
- Dual Functions of Defoaming and Foam Inhibition: Efficiently removes existing foam and prevents new foam formation, ensuring the stability of the testing system.
- No Interference with Test Signals: Does not inhibit the arsenic signal, guaranteeing the accuracy and authenticity of test data.
- Excellent Compatibility: Fully miscible with water, strong acids, and strong alkalis, adapting to the complex chemical environment of AFS testing.
- Stable Performance: The stability of fluorescence intensity test results is not affected by the standing time of the solution after adding the defoamer or the mixing intensity, providing consistent performance.
- Environmentally Friendly and Safe: Odorless, tasteless, and non-irritating, complying with international safety and environmental protection standards for analytical reagents.
Comparative Experimental Data
The following data is obtained from standardized comparative experiments between Atomfair AFS Defoamer 372 and n-octanol, reflecting the performance differences in AFS testing of inorganic arsenic (test object: 4 ng arsenic):
