GB/T 16012-1995 Focus on the determination of mercury in the air of the workshop. This standard uses cold atomic absorption spectroscopy (AAS) method to collect air samples through a specific process, convert mercury into a detectable state, and use cold AtomicAbsorption Spectroscopy for accurate measurement. This method can effectively determine the mercury content in the air of the workshop, providing scientific norms for ensuring the safety of the working environment of the workshop and preventing mercury pollution from harming the health of workers. It is suitable for all kinds of air detection scenarios involving mercury production and use in the workshop.
