ISO 15178 Nickel and Cobalt Analysis by ICP Testing
The analysis of nickel and cobalt in base metals is a critical process in the mining sector, ensuring compliance with international standards and supporting quality control. ISO 15178 specifies the procedure for the determination of nickel (Ni) and cobalt (Co) content using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES).
The method is widely recognized for its accuracy, precision, and speed, making it a preferred choice among laboratories. This technique allows for the simultaneous determination of multiple elements in complex matrices, which is particularly advantageous when analyzing base metals such as copper, zinc, lead, and nickel.
During testing, samples undergo rigorous preparation to ensure representative results. Typically, this involves digestion using strong acids like nitric acid or perchloric acid, followed by dilution to achieve appropriate concentrations for ICP-OES analysis. The choice of acid digestion is crucial as it affects the solubility and stability of the elements being analyzed.
The instrumentation used in ISO 15178 testing includes an ICP-OES spectrometer, which ionizes sample atoms or molecules to produce characteristic emissions that are then detected by a detector. The instrument's calibration is critical for accurate results; it must be performed using certified reference materials and standards traceable to international standards such as ISO.
Once the analysis is complete, the data are processed through software that interprets the spectral lines associated with nickel and cobalt. The final report provides quantitative values for these elements, along with any other metals present in the sample matrix. This comprehensive approach ensures that all relevant elements are accounted for, enhancing both accuracy and reliability.
The standard also includes acceptance criteria to ensure that results fall within specified limits of detection (LOD) and quantification (LOQ). These limits are essential for ensuring that any detected trace amounts do not compromise the integrity of the analysis. The LOD is typically set at a level where the signal-to-noise ratio allows confident detection, while the LOQ defines the lowest concentration that can be reliably quantified.
| Element | LOD (µg/L) | LOQ (µg/L) |
|---|---|---|
| Nickel (Ni) | 0.1 µg/L | 0.5 µg/L |
| Cobalt (Co) | 0.2 µg/L | 1.0 µg/L |
The accuracy of the analysis is further enhanced by using a multi-point calibration curve, which ensures that any deviation from expected results can be identified and corrected. This approach provides robust data quality and supports regulatory compliance.
