ASTM E1621 Multielement Spectroscopy by Glow Discharge OES
The ASTM E1621 standard specifies the procedure for performing multielement quantitative analysis of metallic materials using a glow discharge optical emission spectrometer (GD-OES). This method is widely recognized for its precision and accuracy in identifying trace elements, major elements, and alloying additions within various metals. The process involves subjecting a sample to an intense plasma discharge, which excites the atoms in the sample, emitting characteristic wavelengths of light that are captured by a spectrometer.
The GD-OES technique is particularly advantageous for its speed and efficiency, allowing for rapid analysis even on complex alloy compositions. This makes it ideal for laboratories serving industries such as aerospace, automotive, electronics, and manufacturing where material integrity and compliance with industry standards are critical. The method adheres to the ISO 17025 accreditation, ensuring that results meet international quality benchmarks.
The ASTM E1621 procedure is designed to cover a broad range of elements from trace to major concentrations. It employs a precise calibration process using reference materials and internal standards to ensure accurate quantification. The method also specifies the use of specific wavelengths for each element, which helps in minimizing interferences that can occur during the analysis.
For specimen preparation, a small amount of material is typically ground into a fine powder or pressed into a pellet. This ensures that the sample is homogeneous and representative of the entire batch or lot being analyzed. The method also allows for the analysis of thin films and coatings using appropriate holders to prevent contamination from the substrate.
The results provided by ASTM E1621 are reported in terms of elemental concentrations, typically expressed as weight percent (wt%) or parts per million (ppm). These results can be used to verify compliance with material specifications, identify alloying additions, and ensure that products meet regulatory requirements. The precision and accuracy of the method have been validated through extensive inter-laboratory comparisons.
The ASTM E1621 standard is complemented by other related standards such as ISO 4200-3:2015, which provides additional guidance on sample preparation for GD-OES analysis. By adhering to these international standards, laboratories can ensure the consistency and reliability of their analytical results.
The application of ASTM E1621 is not limited to metallic materials but extends to various types of alloys including stainless steel, aluminum, copper, nickel, and titanium. This versatility makes it a valuable tool for research and development activities where understanding material composition is essential.
In conclusion, the ASTM E1621 method by Glow Discharge OES offers a robust and efficient means for analyzing metallic materials. Its adherence to international standards ensures that results are reliable and widely accepted in both domestic and international markets.
