Offset printing is a widely used technique in the production of printed products such as books, newspapers, and packaging. The process relies on the transfer of an image from an inked surface to the substrate. When used in combination with a lithographic process, it comprises the use of a dampening solution and an oil-based printing ink. The inked surface (plate) is divided into hydrophilic regions, which accept the dampening solution and repel the ink, and hydrophobic regions which repel the dampening solution and accept the ink.
The formulation performance of a product can be affected in a variety of ways by moisture present in the air. 
In aseptic pharmaceutical production, undetected airborne particle contamination from tubing systems can jeopardize

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.
The New ISO 4407 – A Milestone for Microscopic Particle Analysis

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.

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.
Why measure particles in fuel and hydraulic fluids?

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.
