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 het dagelijks leven is het voor het blote oog vrijwel onmogelijk om kleine deeltjes in de lucht te detecteren. In industrieën zoals de farmaceutische industrie, elektronica, gezondheidszorg en voedsel, kunnen deze onzichtbare deeltjes echter direct de productkwaliteit en -veiligheid beïnvloeden. Hier komen deeltjestellers in beeld — gespecialiseerde instrumenten die zijn ontworpen om luchtdeeltjes te 'zien' en te tellen. Maar hoe werkt dit? Het kernprincipe achter een deeltjesteller is de lichtverstrooiingsmethode. Wanneer een luchtmonster in het instrument wordt gezogen, passeert het een detectiezone die wordt verlicht door een laser. Als er deeltjes aanwezig zijn, verstrooien ze het laserlicht. Dit verstrooide licht wordt vervolgens opgevangen door een fotodetector en omgezet in elektrische signalen. Door de intensiteit van het verstrooide licht te analyseren, kan het instrument niet alleen de aanwezigheid van deeltjes bepalen, maar ook hun grootte. In eenvoudige termen laat elk deeltje een 'lichtvoetafdruk' achter wanneer het door de laserstraal gaat. Grotere deeltjes produceren sterkere signalen, terwijl kleinere deeltjes zwakkere signalen genereren. Door deze signalen te analyseren en te tellen, geeft de deeltjesteller een snelle meting van de deeltjesconcentratie over verschillende groottes. In de farmaceutische productie zijn strikte steriele omstandigheden vereist en kunnen overmatige deeltjes de veiligheid van geneesmiddelen in gevaar brengen. In halfgeleiderfabrieken kan zelfs een enkel stofdeeltje leiden tot chipfalen. Deeltjestellers dienen dus als essentiële 'bewakers van de luchtkwaliteit' in moderne industrieën. Met voortdurende ontwikkelingen zijn de huidige deeltjestellers steeds vaker uitgerust met gegevensopslag, bewaking op afstand en intelligente analysefuncties. Van simpelweg 'stof zien' tot het mogelijk maken van uitgebreid luchtkwaliteitsbeheer, deeltjestellers worden onmisbaar in verschillende vakgebieden.
