Environmental monitoring in pharmaceutical manufacturing is more than compliance; it demands practical, reliable strategies for complex controlled environments. This second volume of the Environmental Handbook offers practical guidance for environmental monitoring in glove boxes and isolators, defining microbial sampling criteria, addressing Annex 1 (2022) changes, and examining particle loss in transport tubing. It also covers risk assessment for isolator filling, microbiological sampling techniques, sample‑collection strategies, and data interpretation, supporting effective contamination control and confident decision‑making.
Volume 2 of the Environmental Monitoring Handbook for Pharmaceutical Manufacturers is your updated, essential guide to a deeper understanding of environmental monitoring. The second volume offers a completely new set of materials, including two updated application notes and six chapters written specifically to support this expanded handbook. Chapters cover isolator and glove‑box monitoring, updated microbial and particle sampling criteria, particle‑loss challenges, a risk assessment framework for isolator filling processes, and expert insight on sample collection and Annex 1 changes.

The effective removal of cooling lubricants is essential for ensuring high surface quality and reliable downstream processing.
Contact angle measurements and free surface energy (SFE) analysis offer a fast, efficient, and non-destructive method for
evaluating the performance of cleaning agents after cooling lubricant application. By characterising surface wettability,
residual contamination and cleaning effectiveness can be quantitatively assessed, enabling informed decisions to optimize
processes and conserve resources.

After several years of intensive revision, the updated version of ISO 4407 has finally been released. This marks a real milestone for professionals working in microscopic particle analysis. The new edition of ISO 4407 is ready for the future – practical, open to new technologies, and fully aligned with modern quality processes.
Anyone working with microscopes knows it: ISO 4407 – the standard for manual particle counting on filter membranes. It serves as the counterpart to ISO 11171, which governs the calibration of automatic particle counters for liquids. But while ISO 11171 has undergone continuous updates and adjustments over the years, ISO 4407 remained largely unchanged since the 1980s – until now.

The online particle counter PAMAS S50P Fuel is used asa online measuring instrument for condition monitoring and contamination analysis of liquid fuel(e.g. diesel). The instrument measures the number of particles in eight different size channels and can function as early alerts in case of failures caused by bigger particle sizes (e.g. corrosion). This makes PAMAS S50P Fuel indispensable for preventive condition monitoring of liquid fuel, as it prevents the filling of contaminated fuel into storage tanks. On its 6-digit LED display, the instrument reports the triple code according to ISO 4406. The PAMAS S50P Fuel is equipped with a pump to control the flow rate to 25 ml/min at a pressure range from 0 to 6 bar.

Environmental monitoring in pharmaceutical manufacturing isn’t just about meeting requirements—
it’s about applying them effectively to protect product integrity and patient safety. Grounded in real-world
experience, this handbook translates EU GMP Annex 1 (2022) expectations and Contamination Control Strategy
(CCS) principles into clear, practical guidance. It helps teams strengthen cleanroom control, support compliance,
and maintain confidence in product quality across daily operations.
The Environmental Monitoring Handbook for Pharmaceutical Manufacturers is your essential guide to mastering
cleanroom operations. Whether you’re navigating the latest EU GMP Annex 1 (2022) updates or implementing a robust
Contamination Control Strategy (CCS), this handbook delivers:

The microscope system PAMAS FastPatch 2 GO has been developed to comply with
the standard ISO 4407 as an automated filter membrane particle counting and sizing
system.
The system is designed to measure the particles trapped on the surface of the filter.
The analysis uses advanced image analysis and microscope automation techniques
to provide rapid and accurate contamination results of whole or user specified areas of filters.
The FastPatch 2 GO is especially suitable for:
Dark oils, 2 -phase emulsion or high levels of contamination

Battery manufacturing demands precise control of particulate and molecular contamination to safeguard safety, performance,
and yield. As production scales and processes remain tightly interconnected, robust contamination monitoring brings stability to
operations, minimizes defects, and reduces the risk of costly interruptions. Grounded in real-world manufacturing experience,
this technical paper presents data-driven monitoring approaches that help battery manufacturers maintain control, ensure
consistent quality, and protect yield across the production lifecycle.

An liquid particle counter measures the number and size of the particles in a liquid, but why bother to do that ?
This short article will answer that question.
In the case of hydraulic fluids the hydraulic compents has fine tollerances which can be damaged by to
many particles in the fluid.When maintenance are completed it also best practise to flush the system with clean hyraulic fluid and check the fluid is clean
after the flush before placing the system back into service. Trend monitoring of hydraulic fluids also serve as an early warning of abnormal wear and
possible impending failure in a system.

Ion-exchange membranes are widely used in numerous applications, such as water treatment, chemistry, electrolysis, sensorics and other fields. A good ion transfer selectivity of the ion-exchange membrane is highly important for all of these applications. The charge structure and composition of ion-exchange membranes has a strong influence on the mobility of different ions or molecules and thus governs the selectivity of ion transport processes through the membrane.[1] Therefore, it is of great importance to have a good technique to characterise the charged surface functionalities of ion-exchange membranes.

Physical stability testing is crucial in pharmaceutical development, requiring a thorough understanding of how moisture interacts with materials to ensure tablet integrity and performance. This study explores how tablet porosity and the inclusion of swelling excipients influence moisture uptake and stability across different length and time scales, from particle-level interactions to tablet behaviour and from short-term moisture sorption using dynamic vapour sorption (DVS) to long-term storage effects.

Real-World Gas Adsorption and Separation PerformanceGas separation, carbon capture, VOC removal all have one thing in common: you need accurate, reproducible data before you can trust a material.
Breakthrough analysis delivers that insight, but it’s often slow, complex, and difficult to reproduce.
That’s where the BTA Frontier comes in.

In pharmaceutical manufacturing, cleanroom compliance is critical—but keeping up with evolving global regulations can be overwhelming. From EU GMP Annex 1 to ISO 14644-1, the standards governing cleanroom classification and contamination control are complex and constantly updated. Whether you’re managing cleanroom qualification, regulatory compliance, or contamination monitoring, you need fast access to accurate information—without spending hours searching through lengthy regulatory documents.

Dynamic Vapor Sorption (DVS), invented by Prof. Daryl Williams over 30 years ago, is a groundbreaking gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. This is achieved by varying the vapor concentration surrounding the sample in a controlled environment and measuring the sample’s change in mass. While water vapor is most commonly used to do this, you can also use a range of organic solvents.
