Annex 1 is a regulation that outlines manufacturing requirements for sterile drugs made in and imported to the EU. In August 2022, a new revision of the EU GMP Annex 1 regulatory standard for sterile drug products was released, replacing the most recent draft from 2020 and the existing revision from 2008. Contamination control is vital in pharmaceutical manufacturing, and the requirements for environmental monitoring remain essentially the same in this revision; changes in the recent revision of Annex 1 highlight strategic control through further alignment with existing regulations from other organizations, the concept of a contamination control strategy (CCS), the separation and expanded guidance on Cleanroom Classification and Cleanroom Monitoring, and the definition of Quality Risk Management (QRM) as a central principle to defining processes, operations, and limits.

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.
DVS Resolution is a dual vapor gravimetric analyzer, with key feature, is the combined ability to Question: “What is the need of taking a non-viable particle count after a power shut down for an hour. Our Class C area is stabilizing
after 30 minutes of a power cut?”
There are several reasons for deploying your Non-Viable Environmental Monitoring Program following a power outage,
but primarily it is to ensure that the HVAC has been restored and is now operating optimally – this is the 30-minute
stabilization that you witness in your Grade C areas. Grade C areas have a relatively high air exchange rate
(nominally, 20 air volumes per hour) so stabilization will occur rapidly in the unmanned state.

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.
The Data Quality Concept – A New Challenge for Quality Experts

The role of quality systems in pharmaceutical organizations has grown faster than any other function during the last 15 years. During this period, a small group dedicated to traditional Compliance grew and expanded to include Quality Experts in areas such as validation, product release, operations, sterility assurance, and other specialized functions.
Creating a deeper quality connection between manufacturing and engineering has always been the aim of that growth. Little by little, quality became fundamental to every step of the pharmaceutical manufacturing process: changing from a silo concept to a more fluid one. Now, a new challenge is approaching. The fourth industrial revolution (Pharma 4.0™) is the beginning of the “Smart Facility” era, where digitalization and automation will combine to reach very complex applications and life cycles. In this brand-new framework, Quality Experts will face the challenge of rethinking their roles and redesigning the Quality Systems of their pharmaceutical companies to be based on the concepts of Data Quality.

In January 2022, authors Lizhong Wang et al. published an article in Nature Communications with the title Spontaneous dewetting transitions of droplets during icing and melting cycle
. In it, they describe how the structure of a surface can influence the behaviour of a droplet during freezing and melting.

Extended active microbial sampling is allways of interest due to the possibility
to decrease the number of samples that has to be processed as well as potential
cost savings. Particle Measuring Systems recently released a nice case study
that proves that 4 hours of active sampling is possible.
