and commercial needs for the characterization of nanomaterials or the characterization of particle size and counts in suspension, particle tracking Covering a larger particle size range and being more universal 1), the PTA mentioned in this document covers both NTA and PTA: In this document, PTA is equivalent to at NTA: Based on laser irradiation, scattered light imaging, particle identification and positioning, single particle tracking and other technical means2), PTA can detect particles in suspension: Diffusion motion of particles is measured: Suspension here refers to a homogeneous dispersion of particles, air bubbles or other liquid droplets: Stokes-Einstein equation It is shown that the hydrodynamic diameter of a single particle, droplet or bubble is related to its Brownian motion parameters: In recent years, academia has made great progress in liposomes and other drug carriers, nanotoxicology, viruses, exosomes, protein aggregation, inkjet inks, and pigment particles: PTA technology has been used for characterization in the work of particles, cosmetics, food, fuel additives and microbubbles: ASTM has published a Standard guideline (E2834-12) [10], guidance for nanoparticle tracking analysis NTA measurement of particle size distribution: This document is intended to extend the scope of the specification And promote the systematization of PTA operation: This document provides an overview of the theory, basic principles, advantages and disadvantages of particle tracking analysis, as well as instrument configuration, measurement procedures, system validation and The analysis report and so on are described, and the interpretation and interpretation of the data meaning is one of the important contents: It should be noted that the measured The measurement result is the number and size distribution of particles, and the meaning of particle size is the hydrodynamic diameter of particles in the sample, which is different from that obtained by other methods: Particle size is not the same, such as dynamic light scattering method [6] or electron microscopy (static image method) [4]: 1) NTA is the most recognized abbreviation for the techniques described in this document, but particle tracking analysis (PTA) includes NTA in the particle size measurement range: 2) The meaning of "tracking" in this document is "the tracking of the position of the particle in the x and y directions", and the meaning of "trajectory" is "the tracking of the position of the particle in the x and y coordinates": Set the determined path": Particle Size Analysis Particle Tracking Analysis (PTA)1 ScopeThis document describes the use of particle tracking analysis for the measurement of diffusion velocity for liquid dispersions (solids, liquids suspended in liquids): or gaseous particulate matter) based on the number of particle size distribution methods:2 Normative referencesThis document has no normative references:3 Terms and DefinitionsThe following terms and definitions apply to this document: 3:1 nanoscale nanoscale It is about in the size range between 1nm and 100nm: Note: In this scale range, the main features are not extrapolated from the large size: [Source: ISO /T S80004-1:2015,2:1] 3:2 nano-object nano-object object whose one-, two-, or three-dimensional external dimension is at the nanoscale (3:1): Note: The three-dimensional directions in the external dimensions are perpendicular to each other: [Source: ISO /T S80004-1:2015,2:5] 3:3 nanoparticle nanoparticle A nano-object (3:2) whose outer dimensions in all three dimensions are in the nanoscale (3:1): Note: If the length of the longest axis and the shortest axis of the nano-objects are significantly different (ratio greater than 3), the term nanofiber or nanosheet is used to refer to the nanoparticle: [Source: ISO /T S80004-4:2011,2:4] 3:4 Particle Tiny matter with well-defined physical boundaries: Note 1 to entry: Physical boundaries can also be described as interfaces: Note 2: Particles can move as a whole: Note 3: This general particle definition applies to nano-objects (3:2): [Source: ISO /T S80004-6:2013,2:9] 3:5 Agglomerates agglomerate An accumulation, aggregate, or mixture of the two of weakly bound particles, whose external area is similar to the sum of the surface areas of its individual particles: NOTE 1: The forces supporting the aggregates are all weak forces, such as van der Waals forces or simple physical entanglements: Note 2: Agglomerates are also called "secondary particles", while the source particles are called "primary particles (primary particles)": ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 42348-2023_English be delivered?Answer: Upon your order, we will
