In the world of aseptic pharmaceutical manufacturing, the reliability and safety of utilities are paramount. Utilities can be categorized into two main types: process systems and process support systems. While process support systems do not directly impact product quality or patient safety, process systems are critical as they interact with products or essential materials. One of the most vital process systems in this context is compressed gas.
Compressed gas systems in aseptic manufacturing, including air, nitrogen, carbon dioxide, and gaseous hydrogen, play a crucial role throughout various stages of pharmaceutical processes. Therefore, understanding and managing the risks associated with these systems is essential for maintaining product quality and ensuring compliance with Good Manufacturing Practices (GMP).

In the pharmaceutical 
manufacturing industry, ensuring sterility and minimizing microbial contamination are critical for maintaining product quality and safety. Microbial sampling is a key component of environmental monitoring, and understanding the optimal criteria for sampling can significantly impact the effectiveness of sterility assurance programs.
Introduction to Microbial Sampling Methods
In a pharmaceutical manufacturing facility, microbial sampling is conducted using several methods, each with its own set of instruments and techniques. The primary methods include:
- Surface Sampling: Typically performed using swabs or contact plates to collect microbes from surfaces.
- Passive Aerosol (Air) Environmental Sampling: Involves the use of settle plates to capture airborne particles that settle over time.
- Active Aerosol (Air) Environmental Sampling: Utilizes devices that actively draw air through a collection medium, such as an impactor, to capture airborne microorganisms.

Particle measuring technology is used to control cleanliness of liquids and to identify quality deficiencies and excessive wear in order to avoid eventual costly machine failures. PAMAS particle counters measure solid particulate contamination of liquids and control the efficiency of filters and the cleanliness of liquids.
Particles circulating at high speed and pressure in the liquids of turbines, power plants, gearboxes and offshore applications are capable of damaging mechanical parts of the system.
Particles affect both the quality of liquids (e.g. contaminants in pharmaceutical solutions, drinking water or process water), and also the connected components and machines (e.g. in aviation and hydraulics in general).

Contact electrification (also known as triboelectricity) is a phenomenon that can occur at the interface between two materials. It means that the materials become electrically charged when they come into contact with each other. A well-known, everyday example of contact electrification is when your hair sticks out in all directions after rubbing it against a balloon.
In a recent journal article by Tang et al., the researchers investigated the relationship between electric charge density and wettability behaviour at a solid-liquid interface after contact electrification. The study looked at 24 different materials in total and found a linear relationship between charge density and wettability.

Determination of the surface potential and isoelectric point of ion-exchange membranes with a zeta potential analyzer

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. A powerful technique to evaluate charged surface functionalities is the measurement of the zeta potential, that is, the electric potential of solid surfaces in contact with an electrolyte solution. With this information it is possible to better understand the dissociation state of functional groups on the surface, and conclude the electrostatic interactions that will occur with other materials such as charged particles. The new Zeta Potential Analyzer ZPA 20 from DataPhysics Instruments (Fig. 1) measures the zeta potential of fibres, powders and plate shaped surfaces by means of a novel bidirectional oscillating streaming potential or streaming current technique. In this application note, we study the functional groups of different ion-exchange membrane surfaces with the ZPA 20.

Particle counting efficiency is crucial in particle measurement, especially when using optical particle counters. This term denotes the likelihood of precisely detecting and enumerating particles within a specified size spectrum. In this context, the term “particle counting efficiency” represents the ability of the particle counter to quantify particles of a given size accurately. It measures the instrument’s performance, indicating how effectively it can detect and count particles of various sizes.
The significance of particle counting efficiency lies in its direct impact on the reliability and accuracy of particle measurement. For instance, in applications such as air quality monitoring, pharmaceutical manufacturing, or research in aerosol science, the precision in measuring particle size and concentration is paramount. A higher counting efficiency means the counter is more effective in detecting and counting the particles within its designated size range, leading to more accurate and reliable data.

This study investigates the chemical degradation and dehydration behaviours of pharmaceutical compounds, acetylsalicylic acid (ASA) and citric acid monohydrate, used in drug formulation, stability, and drug delivery systems. The combination of DVS and Raman spectroscopy reveals changes during ASA degradation, influenced by humidity and temperature. Analysing the process of dehydration of citric acid monohydrate is important when understanding drug release mechanisms. This has been shown to be affected by temperature and humidity, with higher humidity necessitating elevated temperatures to produce its anhydrous form. Understanding the changes and kinetics involved in these processes can influence decisions in pharmaceutical design, enhancing drug efficacy and shelf-life.

ng a contamination-free environment is a prerequisite for high-tech manufacturing and scientific research. Cleanrooms are central to this endeavour. Although a cleanroom is a critical part of maintaining a working environment, they cannot guarantee required cleanliness standards without robust monitoring systems such as particle counters and air quality monitors. A cleanroom particle counter directly contributes to air quality by measuring the concentration of airborne particles in the environment, which is essential for quality assurance (QA) and compliance. Here is a guide on how to choose the right particle counter for your cleanroom
