Look How Airborne Particle Counters Have Evolved Over the past 25 years.
With 25 years in business behind us, we’ve witnessed a quarter-century of progress in precision air monitoring. In this time, Airborne Particle Counters (APCs) have undergone a quiet revolution – from bulky instruments with limited data capacity to today’s intelligent units that can operate independently and be integrated into networked systems.
Much of the evolution of particle counters reflects broader advances in sensor technology, automation and cleanroom standards. At FMS, we’ve been at the forefront of this transformation – supporting standalone particle counters as well as integrating into monitoring systems that not only keep pace with technological innovation but help our customers stay ahead of regulatory demands.
Here’s a quick look at how far airborne particle counters have come, and what this means for cleanroom monitoring today.
- Size & Portability
Although particle counters can still be used as standalone instruments, they have evolved from bulky units in the 1990s to small, lightweight portable devices. 25 years ago, integration into facility-wide monitoring systems was uncommon. Today, small-form-factor remote particle counters are easily deployed as part of a monitoring system and are able to fit into tight spaces like isolators.
- Data & Connectivity
Historically, particle counters had limited data storage, with that data often held locally on internal memory or removable storage. Analysis was a very manual process. In contrast, modern units support real-time data transmission, offer much larger storage capabilities with data reviewable on platforms like TSI’s TrakPro™ Lite Secure Software or via seamless integration with facility monitoring systems such as TSI’s FMS 6.
- Sensitivity & Accuracy
Detection limits have improved from 0.3µm to 0.1µm with optical particle counters – or smaller with specialised instruments. This is how we keep ahead of the needs of high precision industries like semiconductors, pharma, space vehicle assembly and advanced materials, where ultrafine contamination poses serious risks. As technology miniaturisation continues, our particle counters can detect the smaller particles that present a hazard or risk.
- Compliance & Standards
Advances in accuracy and Data Integrity ensure alignment with stricter and ever-evolving regulations such as ISO 14644 and EU GMP Annex 1. This helps users to improve the accuracy, reliability and auditability of their systems via reporting capabilities from the particle counter itself or through the designated software.
The Emergence of Viable Particle Counting
Specialist particle counters offer detectable size ranges to 0.1um using diode lasers, and down to 10nm with Helium Neon (HeNe) lasers. But one of the most significant innovations in the past 25 years is the arrival of effective detection and counting of viable airborne particles – those active microbes that present a risk to health, such as bacteria, mould spores and fungi.
Nothing existed like the TSI BioTrak™ Real-Time Viable Particle Counter in the year 2000. Air sampling with settle plates was the only way to capture microbial particles, which took hours for collection and then days for speciation. Now the unique BioTrak is changing the game in pharma and life science aseptic applications. It detects viable particles in real time. With regulatory approval, it’s the only accepted method to replace active and passive air sampling in Grade A environments.
Here’s why it’s changing the game:
- FDA-approved as a non-inferior Rapid Microbial Method (RMM).
- Simultaneous detection of both total and viable particles.
- Instant real-time alerts.
- Inline particle collection filter for speciation.
- Great for continuous monitoring and root cause investigation.
At FMS, we know that BioTrak is part of a bright future for efficient and safe environmental monitoring.
Talking of the future, we believe particle counters are likely to embrace and integrate AI-based diagnostics, predictive maintenance and IoT-based smart facility integration – advances that promise to deliver even greater control, traceability and responsiveness in critical environments.
We remain committed to supporting this evolution, providing our customers with cutting-edge particle counter instruments and monitoring systems, unmatched technical expertise and our famous nationwide support to keep their operations compliant and efficient.
