Owning a high-precision particle counter is the first step in quality control, but ensuring it consistently produces accurate, consistent, and traceable data throughout its years of service depends on an indispensable safeguard: professional periodic calibration and maintenance. Like any precision instrument, a particle counter's performance can drift over time. The laser's intensity may slowly degrade, dust can accumulate on optical surfaces, and the sample pump's flow rate can subtly change—all of which directly impact measurement accuracy. An annual calibration performed in accordance with the international standard ISO 21501-4 is a rigorous scientific process. It is far more than a simple comparison; it involves an "as-found" test of the instrument's initial state, a thorough cleaning of the optical and pneumatic systems, a precise calibration of particle sizing and counting efficiency using standard particles traceable to a National Metrology Institute (like NIST or NIM), and a correction of the sampling flow rate. Upon completion, you receive a detailed calibration certificate, which is the authoritative document needed to prove to auditors and regulatory bodies that your measurement equipment is in a state of control. The global calibration services offered by Suzhou Sujing are designed to help clients protect their equipment investment, mitigate compliance risks and production losses caused by inaccurate data, and serve as the critical link in maximizing the full lifecycle value of their instrument.

In the rigorous workflows of cleanroom validation and routine monitoring, the "human factor" is a critical variable impacting both data quality and operational efficiency. A complex, difficult-to-use instrument increases training costs and is more prone to operator error. Suzhou Sujing understands this well and is dedicated to elevating the user experience to new heights through superior industrial design. Our portable particle counters feature a 7-inch, high-resolution color touchscreen with a UI that adopts modern, smartphone-style icon-based and wizard-driven navigation. The logic is so clear that engineers and technicians can intuitively perform most operations without consulting a cumbersome manual. Users can easily customize sampling location names, create and save multi-step sampling plans, and recall them with a single touch for future tasks, dramatically improving the efficiency and standardization of repetitive work. Upon test completion, results are presented in clear tables and trend graphs, while the built-in thermal printer allows for immediate output of key data for on-the-spot record-keeping. Meanwhile, comprehensive, industry-compliant PDF reports can be effortlessly exported via USB or Ethernet, enabling seamless integration with Quality Management Systems. From the ergonomic handle to the long-life lithium battery that supports a full day's work, every detail is designed to reduce operator burden. This holistic approach can cut the total time for a single validation or inspection round by up to 50%, empowering professionals to focus more on data analysis and process improvement.

As the global energy revolution deepens, the demand for high-performance lithium-ion batteries is growing at an unprecedented rate. However, the cleanliness requirements for the production environments in this cutting-edge manufacturing sector are every bit as stringent as those in the traditional pharmaceutical and semiconductor industries. In the core processes of battery manufacturing, such as electrode coating, cell winding, and packaging, airborne micron-sized particles pose a significant safety hazard. Conductive metallic particles (like iron, copper, and nickel) are especially dangerous; if they land inside a battery cell during assembly, they act like a "micro-bomb." Such a particle can puncture the thin separator, causing a micro-short circuit between the anode and cathode. This can lead to abnormal self-discharge rates, rapid capacity decay, and even localized overheating during cycling, potentially triggering a dangerous thermal runaway event. Therefore, within the dry rooms that demand extremely low humidity and high cleanliness, implementing rigorous air particle monitoring is the first line of defense for ensuring product quality and safety. Suzhou Sujing's high-sensitivity particle counters provide real-time, precise capture and quantification of environmental contaminants. They help battery manufacturers validate the effectiveness of their environmental control systems (like FFUs) and identify potential contamination sources promptly. By maintaining an ultra-clean production environment, companies can significantly improve the consistency, safety, and cycle life of their battery products, thereby securing a competitive advantage in the fierce global market.

The European pharmaceutical industry is navigating a major transformation of its regulatory landscape—the full implementation of the new EU GMP Annex 1. At the heart of this new regulation is the establishment of a comprehensive "Contamination Control Strategy" (CCS), which emphasizes a scientific and risk-based approach. Particularly for Grade A aseptic core zones, the new rules mandate the systematic collection of a 1m³ air sample to obtain more representative environmental data. In this context, the 100 LPM (Liters Per Minute) flow-rate particle counter has transitioned from a "recommended option" to a "definitive choice" for ensuring compliance. Using a traditional 1 CFM (28.3 LPM) instrument to complete a 1m³ sample takes over 35 minutes. In aseptic operations where every second counts, such a prolonged monitoring period significantly increases the risk of operator intervention and environmental exposure. Suzhou Sujing's 100LPM portable particle counter slashes this process to a mere 10 minutes. This translates to less production downtime, a lower risk of human-induced contamination, and the ability to gather more monitoring data within the same timeframe, providing a more robust foundation for trend analysis and risk assessment. It is not merely a tool for meeting regulatory text but a strategic asset that empowers European pharmaceutical firms to optimize their CCS and elevate their sterility assurance levels.

In daily life, it is almost impossible for the naked eye to detect tiny particles suspended in the air. However, in industries such as pharmaceuticals, electronics, healthcare, and food, these invisible particles can directly affect product quality and safety. This is where particle counters come into play—specialized instruments designed to “see” and count airborne particles. But how does this work? The core principle behind a particle counter is the light scattering method. When an air sample is drawn into the instrument, it passes through a detection zone illuminated by a laser. If particles are present, they scatter the laser light. This scattered light is then captured by a photodetector and converted into electrical signals. By analyzing the intensity of the scattered light, the instrument can determine not only the presence of particles but also their size. In simple terms, each particle leaves a “light footprint” when it passes through the laser beam. Larger particles produce stronger signals, while smaller ones generate weaker signals. By analyzing and counting these signals, the particle counter provides a quick measurement of particle concentration across different size ranges. In pharmaceutical manufacturing, strict sterile conditions are required, and any excessive particles may compromise drug safety. In semiconductor plants, even a single speck of dust can cause chip failure. Thus, particle counters serve as vital “guardians of air quality” in modern industries. With continuous advancements, today’s particle counters are increasingly equipped with data storage, remote monitoring, and intelligent analysis functions. From simply “seeing dust” to enabling comprehensive air quality management, particle counters are becoming indispensable across various fields.

Recording and traceability of air monitoring data are vital in pharmaceutical workshop management. The Portable Air Particle Counter, with a built-in thermal printer, allows instant printing of results, avoiding delays and errors from manual recording. It also offers large-capacity storage for long-term data retention. For Lab Pharmaceutical Factory, this significantly improves management efficiency and supports quick access to records during production and audits. With the innovative design of Suzhou Sujing, the device has become an effective tool for improving cleanroom management efficiency in Southeast Asian pharmaceutical factories.
