ISO 18827 Metal Nanoparticle Analysis by ICP MS
The ISO 18827 standard specifies a method for quantifying metal nanoparticles in complex matrices using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This test is essential for ensuring the quality and safety of products containing metal nanoparticles, which are widely used across various sectors including electronics, cosmetics, pharmaceuticals, and environmental remediation.
The analysis targets particles with diameters ranging from 1 to 100 nanometers. The method involves several critical steps: sample preparation, digestion, filtration, dilution, and ultimately the ICP-MS measurement. This process allows for precise quantification of metal nanoparticle concentrations in diverse media such as air, water, soil, or biological samples.
One of the primary reasons ISO 18827 is important is its applicability to a wide range of industries. It ensures that products containing nanoparticles meet regulatory standards and do not pose risks to human health or the environment. For instance, in pharmaceuticals, ensuring the stability and efficacy of drug formulations depends on accurate nanoparticle quantification. In cosmetics, it guarantees that nano-silver particles used as preservatives are at safe levels.
The test is particularly crucial for sectors where trace amounts of metals can significantly impact performance or safety. This includes electronics manufacturing, where gold nanoparticles play a critical role in the production of high-performance semiconductors and circuits. In environmental remediation, the presence of heavy metal nanoparticles can determine the effectiveness of treatment processes.
The ISO 18827 method is robust due to its reliance on ICP-MS technology, which offers high sensitivity and selectivity even for trace metals in complex matrices. However, achieving accurate results requires careful sample preparation, ensuring that all particles are uniformly dispersed without aggregation or loss.
Sample preparation typically involves digestion of solid samples using strong acids like nitric acid to dissolve the matrix while preserving nanoparticle integrity. For liquid samples, filtration and dilution steps ensure that only the relevant fraction of nanoparticles is analyzed. The precision of these preparatory steps directly influences the accuracy of the final results.
ICP-MS instrumentation used in this analysis is equipped with a nebulizer to atomize the sample into an ionized plasma stream, which then enters the mass spectrometer for separation and detection. This setup allows for the simultaneous quantification of multiple elements within a single run, making ISO 18827 particularly efficient.
The acceptance criteria for this test are stringent, ensuring that only particles within the specified size range are counted as metal nanoparticles. Results must meet predefined limits set by regulatory bodies to ensure compliance with international standards like ISO 18827 itself and other relevant directives such as REACH in Europe or TSCA in North America.
The comprehensive nature of this test makes it indispensable for industries reliant on the use of metal nanoparticles. It provides a reliable means to monitor production processes, validate product specifications, and ensure compliance with health and safety regulations. By adhering to ISO 18827, companies can enhance their reputation as responsible and innovative leaders in their respective fields.
