From August 30 to September 5, the 12th International Aerosol Conference (IAC2026) was grandly held in Xi’an. Co‑hosted by the International Aerosol Research Assembly (IARA) and the Chinese Society of Particuology (CSP), the conference was organized by the Institute of Earth Environment, Chinese Academy of Sciences; the Institute of Atmospheric Physics, Chinese Academy of Sciences; Xi’an Jiaotong University; and Shaanxi Key Laboratory of Atmospheric Pollution and Haze.

Nearly 1,000 representatives, including top experts, scholars, research institutions and industrial enterprises from across the globe in the fields of atmospheric environment, aerosol research and ecological monitoring gathered at the event. It represents the most high‑profile and influential top academic event in the global aerosol community.

The opening ceremony of the conference was presided over by Professor Cao Junji from the Institute of Atmospheric Physics, Chinese Academy of Sciences, kicking off exchanges on cutting‑edge aerosol technologies, collision of academic achievements and collaborative industrial innovation worldwide.

Held every four years, the International Aerosol Conference (IAC) focuses on core research areas including aerosol physics, chemistry, climate effects, environmental governance and health impacts. It serves as the premier academic exchange platform for global aerosol‑related research.

Under the central theme of “Breathe the Same Air, Share a Common Fate”, this conference covers a wide range of topics: aerosol formation and evolution, aerosol‑climate interactions, air quality and human health, advanced observation and instrumentation technologies, artificial intelligence and atmospheric modelling, aerosol nanotechnology, as well as pollution control. It showcases the latest international advances in aerosol science and technology.

Hangzhou Shallow-sea Technology participated in the concurrent Instrument Achievement Exhibition of the conference with five core aerosol detection instruments. Delivering high‑precision and multi‑dimensional aerosol monitoring solutions, the company engaged with global research peers to discuss innovations in aerosol detection technologies, atmospheric environmental governance and cutting‑edge trends in climate research, demonstrating its robust capabilities in high‑precision detecting instruments.

With years of dedication to the atmospheric‑environment monitoring sector, Qianhai Technology specializes in the R&D, manufacturing and technological innovation of aerosol, meteorological and hydrological detection equipment, focusing on high‑end research‑grade precision monitoring instruments.

For IAC2026, the company selected five core aerosol‑detection devices, covering full‑application scenarios including aerosol lidar detection, fog‑droplet spectrum analysis, passive cavity detection, black‑carbon analysis and particle‑size spectrum monitoring. These instruments cater to diverse application scenarios such as university research, environmental monitoring, meteorological observation and atmospheric mechanism research.

• Multi‑scattering Aerosol Lidar (MPL‑5000): As a core instrument for three‑dimensional atmospheric aerosol monitoring, it enables all‑day, automatic and high‑precision detection of aerosol vertical profiles. It accurately captures aerosol distribution, planetary boundary‑layer height, and spatiotemporal evolution characteristics of haze and fog. The system is widely applied in regional air‑quality monitoring, pollution source tracing and three‑dimensional observation research of atmospheric environment.

Fog‑Droplet Spectrum Analysis System (SFM‑2000): Designed for precise measurement of microphysical parameters of fog droplets, this system efficiently acquires core data including fog‑droplet particle size, number concentration and liquid water content. It provides accurate data support for cloud‑fog physics research, weather modification, near‑surface fog‑disaster monitoring and research on atmospheric micro‑circulation mechanisms.

• Passive‑Cavity Aerosol Detection System (SPCASP‑200): Adopting high‑precision passive‑cavity detection technology, the instrument features high stability, ultra‑low noise and high sensitivity. It can accurately measure particles with diameters ranging from 0.10 μm to 3.0 μm. It is suitable for high‑precision research scenarios including long‑term continuous scientific observation, atmospheric‑environment monitoring, and analysis of aerosol physicochemical properties.

• Single‑Particle Black‑Carbon Analysis System (SP2‑D): Focused on the precise detection of atmospheric black‑carbon aerosols, this system enables refined analysis of the mass, particle size and mixing state of individual black‑carbon particles. It accurately characterizes emission signatures, transport patterns and climate effects of black‑carbon aerosols, serving as an important research‑grade instrument for studies on atmospheric carbon cycles, pollution source tracing and climate impacts.

• Aerosol Particle‑Size Spectrum Analysis System (SEMS): Capable of precise monitoring of aerosol particles across multiple size ranges, the system rapidly and continuously acquires key data such as particle‑size spectrum distribution and number concentration of atmospheric particulates. It provides comprehensive, accurate and continuous observational data for research on aerosol physicochemical properties, analysis of regional pollution characteristics and scientific studies of atmospheric‑environment mechanisms

Aerosols constitute key factors affecting atmospheric conditions, climate change, air quality and human health. Precise, efficient and refined aerosol‑detection technologies form the core foundation for atmospheric science research and ecological‑environmental governance.
