Your needs: identify and count contaminant particles
Particle counting is essential for quality control and preventing contamination in demanding sectors such as pharmaceuticals and microelectronics. This analysis enables certain particles to be detected and characterized, meeting strict standards and industrial needs in terms of safety and performance. FILAB offers tailor-made solutions for analysing contaminants and particles.
Particle counting
Particle counting is an analytical technique used to quantify and characterize the presence of particles in a sample, be it a liquid or gaseous medium, or the raw materials used in production processes.
Particle counting measures the size, shape and distribution of particles, and provides valuable data for understanding the processes at play in the systems under study. The particle counting process involves the use of particle counters that detect and count particles, often expressed in micrometres.
Particles identification
Combining particle counting with detailed identification is essential for guaranteeing control of production environments and product quality in demanding industries.
Counting quantifies the number and size of particles, while identification reveals their nature (metallic, organic, inert) and origin (equipment wear, packaging, environment). This combined approach makes it possible to prevent contamination, resolve critical problems (batch rejections, technical failures) and comply with strict standards.
Why combine counting and identification?
The combination of counting to quantify and identification to characterise provides a complete picture of the particles present. This makes it possible to :
- Prioritise corrective actions according to the type of contaminant.
- Propose appropriate solutions to limit risks (equipment changes, process adjustments).
- Guarantee compliance with strict standards and regulations (USP 788 Particle cleanliness analysis according to the standard ISO 16232 for the automotive industry, European Pharmacopoeia).
Samples and materials
Particle counting and particle identification can be carried out in a variety of matrices depending on industrial needs and the sectors concerned.
Liquid matrices :
- Pharmaceutical solutions: injectable medicines, vaccines, serums.
- Water: ultrapure water for microelectronics, purified water used in pharmaceuticals.
- Cosmetics: Lotions, creams or gels containing liquid phases.
Gaseous matrices
- Cleanroom air: control of airborne particles to ensure the cleanliness of sterile environments.
- Industrial gases: monitoring the purity of gases used in manufacturing processes, such as microelectronics or chemicals.
Solid matrices
- Pharmaceutical powders: active ingredients, excipients or powder mixtures.
- Industrial materials: debris on surfaces or resulting from mechanical wear.
- Particles on medical devices: analysis of particles deposited on implants, syringes or other equipment.
Complex matrices
- Biological: body fluids or culture media used in biotechnology.
- Composite products: polymers, alloys or coating materials.
- Environmental samples: deposits collected on filters or surfaces.
Why carry out a particle analysis of contaminants?
Particle counting of contaminants makes it possible to identify, measure and characterise particles likely to compromise product performance, safety or reliability. This analysis also has regulatory implications, specific to each industry.
Microscopic counting is used to detect particles such as :
- Inorganic particles: metals or silicates.
- Organic particles: fibres or polymer residues.
- Biological particles: cellular debris.
The method is adapted to identify both visible and sub-visible particles, according to the size criteria defined in the standard.
Contaminants identified by particle counting
Particle counting is used to control contamination and guarantee product quality. As a particle counting laboratory, we frequently monitor certain types of contaminants:
Industrial sector :
– Metal particles: from wear and tear on machinery, important in the mechanical industries.
– Dust and debris: from materials processing, affecting the finish of products.
– Combustion particles: derived from combustion processes, typical in welding operations.
– Chemical particles: residues of manufacturing chemicals, requiring control to avoid contamination.
Pharmaceutical sector:
– Inert particles: Dust and other residues that can cause cross-contamination between products.
– Fibres and equipment: From clothing, packaging materials or the wear and tear of medical devices, which can contaminate medicines during packaging.
These analysis require high sensitivity to detect and quantify contaminants, in order to maintain product safety and integrity in highly regulated environments.

Particle counting in the pharmaceutical industry
Particle counting is a crucial stage in the drug manufacturing process in the pharmaceutical industry. It involves measuring the number of particles present in a product, and identifying them, in order to ensure the safety and quality of the medicine.
Particle counting is carried out using sophisticated and precise instruments, such as laser particle counters. These instruments allow rigorous control of raw materials, excipients and the final product.
They also enable particulate contaminants to be accurately identified and counted. In the pharmaceutical industry, particulate contaminants can take different forms, such as fibres, organic or mineral particles, and can cause harmful effects. Thanks to these analysis, manufacturers are able to determine the source of contaminants and implement preventive measures to ensure risk-free production.
