Enhancing Quality Control and Efficiency in Parenteral Drug Manufacturing with PolyCHECK Particle Identification Service

by | Jun 1, 2023


Maintaining the highest quality standards in parenteral drug manufacturing is vital to ensure the safety and efficacy of medications. The detection and elimination of visible particles play a critical role in quality control processes. Traditional manual and automated inspection methods have limitations when it comes to definitively identifying the source of particles. However, the PolyCHECK particle identification service introduces a game-changing solution. This innovative service allows quality engineers to efficiently sample the entire production train for particle contamination, enabling the definitive identification of material and process sources of visible particles. In this blog post, we will explore how the PolyCHECK particle identification service reduces the cost of quality in parenteral drug manufacturing facilities and streamlines inspection processes for subsequent batches.

The Power of Comprehensive Sampling

The PolyCHECK particle identification service revolutionizes quality control by providing comprehensive sampling capabilities throughout the production train. By utilizing specialized wipers and advanced techniques, quality engineers can efficiently collect samples from various stages of the manufacturing process, including equipment, surfaces, and rejected products. This comprehensive sampling approach enables a holistic analysis of particle contamination and facilitates the identification of the source.

Sophisticated Analysis Techniques

The collected samples undergo rigorous analysis using advanced techniques such as Scanning Electron Microscopy/Energy Dispersive X-ray (SEM/EDX) and Fourier Transform Infrared (FTIR) analysis. These techniques allow for detailed characterization of the particles, including their elemental composition and molecular structure. Quality engineers can identify the material and process source of visible particles by comparing the rejected product and contamination samples.

Benefits of the PolyCHECK Particle Identification Service:

  1. Improved Quality Control: The PolyCHECK particle identification service offers a precise and accurate method for identifying the source of visible particles. Quality engineers can implement targeted root cause corrective actions by identifying the material and process sources. This proactive approach leads to improved quality control and a significant reduction in particle-related issues, ensuring the safety and efficacy of parenteral drug products.
  2. Streamlined Inspection Processes: Traditional inspection methods often rely on random sampling, leading to potential uncertainties in identifying particle sources. The comprehensive sampling capability of the PolyCHECK service allows for a more thorough examination of the entire production train, leaving no stone unturned. This comprehensive approach reduces the need for extensive inspections and expedites subsequent batch release, streamlining the overall inspection process.
  3. Cost Reduction: By quickly sampling the entire production train and employing advanced analysis techniques, the PolyCHECK service enhances operational efficiency and reduces costs. The definitive identification of particle sources allows for targeted corrective actions, minimizing the risk of recurring contamination. This leads to cost savings by reducing waste, preventing unnecessary rejections, and optimizing resource allocation in quality control efforts.
  4. Regulatory Compliance: The PolyCHECK particle identification service aligns with regulatory requirements for root cause analysis and corrective actions. The ability to definitively identify particle sources and document the inspection process ensures compliance with stringent regulations. This maintains the facility’s reputation and provides reassurance to regulatory bodies and patients about the commitment to quality and safety.


The PolyCHECK particle identification service is a groundbreaking solution that enhances quality control and efficiency in parenteral drug manufacturing facilities. By enabling comprehensive sampling of the entire production train and employing sophisticated analysis techniques, this service allows for the definitive identification of material and process sources of visible particles. With improved quality control, streamlined inspection processes, and reduced costs, pharmaceutical manufacturers can optimize productivity, maintain regulatory compliance, and deliver safe and effective parenteral drug products. Implementing the PolyCHECK particle identification service marks a significant step forward in enhancing the quality and efficiency of the manufacturing process, benefiting both the industry and the patients it serves.
