Introduction
Micro-bubble technology can enhance processes or applications in cleaning, chemical, aquaculture and agricultural fields.
Characterization of ultrafine bubbles is crucial for further development of industrial applications. Some characteristic parameters (such as bubble size, bubble number are stable
properties, bubble number concentration and other physical and chemical characteristics) are very important in applications. To provide verifiable characterization platforms for these applications
Taiwan, this document specifies a set of ultrafine sparkling water sampling and sample preparation methods. This method makes it easy to disperse fine bubbles
Characterization performs reliable correlation analysis and predictive analysis of possible application effects.
In general, the sample preparation technique depends on the characterization technique used.
"Fine Bubble Technology Measurement Sampling and Sample Preparation" aims to standardize micro bubble measurement sampling and sample preparation. It is currently published by
Made up of one part.
---Part 1.Ultrafine bubble water dispersion system. The purpose is to establish the sampling and preparation method of ultrafine bubble water dispersion system.
Microbubble technology measurement sampling and sample preparation
Part 1.Ultrafine bubble water dispersion system
1 Scope
This document describes the sampling and sample preparation steps and conditions for ultrafine bubble water dispersions.
This document applies to relatively stable dispersion systems, that is, the number and size of bubbles are relatively stable during sampling, sample preparation and testing.
This document does not apply to unstable fine bubble dispersion systems or microbubble dispersion systems.

GB/T 41914.1 Microbubble Technology General Principles for the Use and Measurement of Microbubbles Part 1.Terminology (GB/T 41914.1-
2022,ISO 20480-1.2017,IDT)
3 Terms and definitions
The terms and definitions defined in GB/T 41914.1 and the following apply to this document.
3.1
A liquid containing fine air bubbles.
3.2
diluent waterdiluent
Used for dilution, homogeneous water without any negative effects and with a known number and concentration of ultra-fine bubbles.
Note 1.Dilution water is used to reduce the number and concentration of ultrafine bubbles in the dispersion system, and does not change the total number of ultrafine bubbles and the particle aggregation state, size or surface
academic nature.
Note 2.When evaluating ultrafine bubbles, dilution water with a concentration of zero ultrafine bubbles is called blank water.
3.3
A liquid containing ultrafine bubbles.
3.4
A liquid containing microbubbles.
4 Liquids for sampling and sample preparation
The liquid used for sampling and sample preparation should be an ultrafine bubble dispersion system, and during the sampling, sample preparation and measurement processes, the size of the ultrafine bubbles should be
size and number concentration values, as well as other characteristics.
