ISO 10722 Determination of Titanium in Nickel Alloys
The ISO 10722 standard provides a method for the determination of titanium in nickel alloys using electrothermal atomic absorption spectrometry (ETAAS). This technique allows for precise quantification of titanium content, which is crucial for ensuring product quality and compliance with industry standards.
Nickel alloys are widely used across various sectors including aerospace, chemical processing, power generation, and medical devices. The presence of trace elements like titanium can significantly impact the mechanical properties, corrosion resistance, and overall performance of these materials. Accurate determination of titanium content is essential for quality control, process optimization, and regulatory compliance.
The ISO 10722 method involves several key steps: sample preparation, atomization in a high-temperature graphite tube, and measurement of the atomic absorption spectrum. The analytical precision and accuracy of this technique are ensured by rigorous calibration procedures and quality control measures.
For accurate results, proper specimen preparation is critical. This includes the dissolution of the nickel alloy into an appropriate matrix to ensure that all titanium present in the sample is available for measurement. The choice of acid mixture plays a significant role in ensuring complete dissolution without interfering with the analysis.
The use of electrothermal atomic absorption spectrometry allows for highly sensitive detection limits, typically ranging from 0.1 to 5 μg/g depending on the concentration range being analyzed. This makes the method suitable for both routine quality control and research applications where minute amounts of titanium need to be detected.
The standard specifies detailed procedures for calibration, including the preparation of a series of standards covering the expected range of titanium concentrations in the samples to be tested. This ensures that any sample can be accurately placed within this calibrated range, enhancing the reliability of the results.
Quality control is an integral part of the ISO 10722 process. Regular checks on instrument performance and adherence to standard operating procedures are necessary to maintain the precision and accuracy of the measurements. This includes periodic calibration of the spectrometer and verification of the calibration standards used in the analysis.
The results from this method can be reported as mass percentage or parts per million (ppm) depending on the requirements of the specific application. Reporting should include all relevant parameters such as detection limits, precision, and accuracy statements to ensure transparency and reproducibility.
Understanding the titanium content in nickel alloys is vital for optimizing manufacturing processes and ensuring product quality. By adhering to ISO 10722 standards, industries can achieve consistent and reliable results that meet both internal and external requirements.
Scope and Methodology
The scope of the ISO 10722 method encompasses the determination of titanium in nickel alloys by electrothermal atomic absorption spectrometry. The method is designed to provide accurate quantitative results for trace amounts of titanium, which can vary widely depending on the specific alloy composition.
The methodology involves several key steps: sample preparation, atomization, and spectral analysis. Sample preparation typically includes dissolution of the nickel alloy in a suitable acid mixture followed by dilution if necessary. The prepared solution is then introduced into the graphite tube where it undergoes atomization at high temperatures.
Once atomized, the titanium atoms are excited to emit characteristic atomic absorption spectra. The intensity of these emissions is measured and compared against reference standards to determine the concentration of titanium in the sample. This process ensures that even very low levels of titanium can be accurately quantified.
The method specifies detailed procedures for each step, including the selection of appropriate acids, the temperature settings for atomization, and the spectral conditions required for optimal measurement. These precise instructions are intended to minimize variability and ensure consistent results across different laboratories.
Calibration is a critical component of the ISO 10722 method. A series of calibration standards with known titanium concentrations is prepared and used to establish a linear relationship between the measured absorbance and the concentration of titanium in the sample. This standard curve allows for accurate determination of unknown samples by interpolation.
Quality control measures are also outlined in the ISO 10722 standard. Regular checks on instrument performance, including spectral purity and stability, ensure that the results remain reliable over time. Additionally, duplicate measurements and comparison with certified reference materials help verify the accuracy and precision of the analysis.

The ISO 10722 method offers numerous benefits to industries dealing with nickel alloys. Primarily, it provides accurate and reliable quantification of titanium content, which is essential for ensuring product quality and compliance with industry standards. This accuracy is critical in sectors such as aerospace where the mechanical properties of materials can significantly impact safety and performance.
By adhering to ISO 10722, industries can achieve consistent results that meet both internal and external requirements. This consistency enhances confidence in the reliability of manufactured products, which is crucial for maintaining a competitive edge in the market.
The method also supports quality control by allowing regular monitoring of titanium content during manufacturing processes. This proactive approach helps identify any deviations from desired specifications early on, enabling timely adjustments to be made. Such measures can prevent costly rework and improve overall efficiency.
