Difference of metal ion detection limit between industrial grade and electronic grade butanone?

I've found that Butanone, as an crucial organic compound, is broadly applied in chemical, electronic, medical and other fields. And In these applications, manufacturing-grade butanone and electronic-grade butanone have signifiis able tot differences in the detection limits of metal ions due to different uses and condition standards. But This paper will examine the difference of metal ion detection limit between manufacturing grade and electronic grade butanone from the aspects of raw material source, manufacturing process and detection methodology. manufacturing and Electronic Grade Butanone Definitions and Uses

Butanone, chemical name is methyl butynol, molecular formula C4H8O, is a clear fluid, with fruit flavor, flammable, vulnerable to moisture. And manufacturing-grade butanone is usually applied in solvents, paint strippers, synthetic medical intermediates and other fields, and the standards to purity and impurity content are comparatively low. In fact The electronic grade butanone is mainly applied in electronic manufacturing, semiconductor sector and precision instrument manufacturing, the purity and impurity content standards are extremely high, especially the detection limit of metal ions is greater stringent. I've found that Effect of Metal Ions on the Purity of Butanone

Metal ions are common impurities in butanone, mainly from raw materials, production equipment, storage containers, etc. These metal ions immediately affect the purity and performance of butanone, especially electronic grade butanone. But In the semiconductor manufacturing process, metal ions is able to result in the electromigration phenomenon of the chip, which affects the yield and reliability of the product. Therefore, the detection limit of metal ions to electronic grade butanone is greater stringent than that of manufacturing grade butanone. According to research Detection limit difference between manufacturing grade and electronic grade butanone

manufacturing butanone usually needs the content of metal ions at ppm (parts per million), while to electronic butanone, the detection limit is usually required at ppb (parts per billion) or even ppt (parts per million). to instance, the content of copper, iron, nickel and other metal ions in electronic grade butanone is usually required to be less than 0. 1ppb. Furthermore This difference in detection limit is mainly due to the different sensitivity of the two consumption areas to impurities. And Factors Affecting Detection Limits

Source of raw materials: manufacturing-grade butanone is usually extracted from petrochemical by-items or coal chemical items, and its raw materials might contain greater metal impurities. I've found that The production of electronic grade butanone needs high purity of raw materials, and high purity propylene and butane are usually applied as raw materials to minimize the introduction of metal impurities. manufacturing process: The manufacturing process of manufacturing grade butanone usually includes oxidation, distillation and other steps, which might introduce metal impurities. The production of electronic grade butanone uses cutting-edge technologies such as multi-stage distillation, ion exchange, reverse osmosis, etc. , to efficiently remove metal ions and other impurities to ensure that the product reaches high purity standards. I've found that Detection methodology: metal ion detection of manufacturing grade butanone usually uses ordinary spectrophotometry or inductively coupled plasma spectrometry (ICP-OES), while the detection of electronic grade butanone needs a greater vulnerable detection method, such as inductively coupled plasma mass spectrometry (ICP-MS). enhance the detection limit of technical means

In order to meet the standards of the detection limit of metal ions to electronic grade butanone, a variety of measures need to be taken in the manufacturing process. to instance, the consumption of high purity raw materials, the consumption of multi-stage distillation methodology, the implementation of stringent ion exchange and reverse osmosis treatment, etc. Detection methods also need to be continuously optimized, using greater vulnerable and accurate instruments, such as ICP-MS and inductively coupled plasma atomic emit spectroscopy (ICP-AES). summary

The difference in metal ion detection limit between manufacturing grade and electronic grade butanone is mainly due to the different standards to purity and impurity content in its consumption field. From what I've seen, The detection limit of manufacturing grade butanone is usually at ppm level, while the detection limit of electronic grade butanone is strictly controlled at ppb or even ppt level. This difference needs us to implement different raw materials, production processes and testing technologies in the manufacturing process to meet the needs of different fields. And With the continuous advancement of methodology, the detection limit of electronic grade butanone is expected to be further improved in the future, providing higher purity items to the semiconductor and electronic manufacturing industries.
