Within chemical scientific research, laboratory air cleanliness serves as an essential foundation for accurate experimental data, prevention of sample contamination, and credible research outputs. Micron-sized airborne particles readily disrupt delicate workflows including precision chemical synthesis, material property characterization and trace component analysis, leading to experimental deviations and wasted test samples. To fully upgrade its laboratory environmental testing system and standardize clean experimental environments, Zhejiang Institute of Chemistry has recently completed equipment procurement and deployed three particle counter models from Kangqi Environmental: the KQET-5018S, KQET-5108L and KQ-4010. The full product lineup caters to all cleanliness testing demands across the institute’s diverse laboratory facilities.

As a core regional chemical research institution, Zhejiang Institute of Chemistry conducts in-depth studies across key disciplines such as fine chemicals, advanced new material development, environmental chemical analysis and chemical safety testing, undertaking numerous critical research projects and technological development initiatives. Its laboratory complex encompasses precision synthesis labs, material characterization labs and general analytical labs, each with distinct requirements for particle detection precision, measuring range and testing throughput. The institute’s legacy testing equipment lacked versatility across varied working zones and failed to support dynamic monitoring for high-standard scientific experiments. The targeted procurement of multiple professional instruments effectively fills gaps in the laboratory’s analytical hardware capabilities.

The three newly introduced devices deliver differentiated yet complementary functionality, forming a full-coverage, multi-tier cleanliness monitoring ecosystem:

1. The KQET-5018S High-Precision Airborne Particle Counter is engineered for sophisticated cutting-edge research environments. It detects ultra-fine suspended particles with minimal measurement deviation and outstanding operational stability, making it ideal for experiments with stringent cleanliness thresholds, such as advanced functional material synthesis and trace chemical analysis. It eliminates distortions to experimental results caused by trace particulate impurities.

2. The KQET-5108L features a high-flow sampling architecture that delivers superior testing efficiency. Optimized for full-area cleanliness verification in large clean laboratory spaces and constant temperature & humidity test chambers, it completes wide-ranging environmental scans rapidly for routine monitoring and acceptance inspections of large-scale experimental zones.

3. The KQ-4010 Portable Particle Counter stands out for its lightweight build and user-friendly operation. It adapts seamlessly to daily laboratory patrols, equipment commissioning and spot sampling at discrete monitoring points. Researchers can swiftly carry out multi-point measurements to track real-time environmental fluctuations, greatly boosting daily laboratory maintenance efficiency.

All three instruments comply with standard testing specifications for scientific laboratories, support permanent data storage and full traceability, and meet professional requirements including research compliance audits and experimental environment filing.

This equipment procurement represents a key initiative by Zhejiang Institute of Chemistry to upgrade its research infrastructure and standardize laboratory administration. Equipped with Kangqi Environmental’s professional cleanliness testing hardware, the institute has realized precise, round-the-clock and standardized supervision of laboratory clean environments. By eliminating experimental errors stemming from ambient contaminants at the source, the consistency and credibility of all chemical experiments have been markedly enhanced. Moving forward, this full-scenario monitoring system will continuously underpin the institute’s research breakthroughs, technological innovation and project development, advancing high-quality progress for regional chemical science research.
