Introduction

Technical Background and Evolution of the Standard

As the first systematic grain characterization specification for imaging materials, this standard fills a gap in the quantitative analysis of the microstructure of silver halide photosensitive materials. With the advancement of digital imaging technology, the precise characterization of traditional silver halide grains and new silver behenate grains has become a critical step in quality control.

Comparison of sample preparation processes

摘要

In vitro cytometry analysis

Analysis of the 3D ELISA kit

Control the ultrasonic dispersion time to 3-5 minutes to prevent over-crushing.
• Maintain the gold plating thickness at 10-15nm to avoid signal shielding.

3. Data Reporting Specifications

Must include: particle source, separation method, shape classification basis, size distribution histogram

Technology Evolution Trends

This standard incorporates traditional silver halide and new silver behenate particles into a unified characterization system for the first time, and may be expanded in the future:
• Dynamic light scattering (DLS) nanoparticle detection method
• Artificial intelligence image recognition and automatic classification technology
• 3D tomography reconstruction technology
