GB/T 11446.7-2013
ActiveTest method for trace anion in electronic grade water by ion chromatography
电子级水中痕量阴离子的离子色谱测试方法
Application Summary AI generated
This standard specifies the ion chromatography method for determining trace anions, such as fluoride, chloride, and sulfate, in electronic grade water. It is applied in the semiconductor, microelectronics, and flat panel display industries to verify water purity during manufacturing processes, ensuring that ultrapure water meets stringent quality requirements for rinsing and chemical dilution. The test is critical for preventing ionic contamination that could compromise device performance and yield.
