Introduction

This document correlates frequently measured nanoobject parameters with the corresponding measurement techniques and is a tool for nanotechnology stakeholders to rapidly determine nanomaterials:

Useful tool for measuring information about objects: The measurands of common nano-objects are listed in row 1 of the quick look-up table (see Table 1): If listed in the moment

If the measurement technique for the first column of the array is applicable, mark the intersection of the corresponding row and column in the table: If you need to learn about a measurement technique, you can

The chapter finds descriptions of the corresponding measurement techniques, their advantages and disadvantages, relevant standards, measurands, and the measurable nanoobject parameters for each technique: With technology

As more measurement techniques develop, this document will be regularly reviewed and updated to maintain its applicability:

Some of the measurement techniques listed in this document have not been verified by comparative experiments or other measurement methods: This document is intended as a relevant measurement

A repository of technical information, but not the final or original repository: Readers can refer to relevant standards after determining a certain measurement technology, and

Application for literature research: Other reference materials include instrument instructions and technical literature:
