What is PD CEN/TS 17273 - Nano-objects in complex matrices about?
PD CEN/TS 17273 discusses nano-objects in complex matrices in nanotechnologies. PD CEN/TS 17273 outlines requirements for sampling and treatment of the complex matrices to obtain a liquid dispersion with a sufficiently high concentration of the nano-objects of interest.
PD CEN/TS 17273 provides guidelines for the detection and identification of specific nano-objects in complex matrices, such as liquid environmental compartments, wastewater, and consumer products (e.g., food, cosmetics).
PD CEN/TS 17273 requires the identification of a priori knowledge of the nature of the nanoobjects like their chemical composition. The selected detection and identification methods are based on a combination of size classification and chemical composition analysis.
Identification can also be supported, e.g., by additional morphology characterization. Currently only field-Flow Fractionation, Electron Microscopy, and single-particle Inductively Coupled Plasma – Mass Spectrometry fulfill this combination condition.
Who is PD CEN/TS 17273 - Nano-objects in complex matrices for?
PD CEN/TS 17273 on nano-objects in complex matrices is useful for:
- Nanotechnologies manufacturers
- Test centers for nanotechnology
- Regulatory bodies
Why should you use PD CEN/TS 17273 - Nano-objects in complex matrices?
Nanotechnology is a rapidly developing field of science and technology that focuses on processes and materials at the nanoscale size (particle dimensions that are approximately 1 nm to 100 nm). It is a highly multidisciplinary field with a wide range of materials and applications, e.g., health care, information and communication technologies, energy production and storage, materials science/chemical engineering, manufacturing, environmental protection, consumer products (e.g., food, cosmetics, etc.).
PD CEN/TS 17273 guideline assists you with possible tasks, measuring techniques, examples for detection and identification tasks in complex matrices, an overview of measurement techniques, guidance on sample preparation, particle detection, identification of nanoobjects in complex matrices, selected measuring techniques for the detection and identification of nanoobjects, list of reporting requirements on sample preparation, detection, and identification of nano-objects in complex matrixes.
This assists in detecting and identifying nano-objects in complex matrices properly and obtaining reliable results.
In addition, PD CEN/TS 17273 guides in combining size measurements with chemical identification for each particle.
