Industrial Particle Contamination Control

Particle contamination causes product deterioration and challenges quality control in every industry and everywhere in the product life cycle. With over three decades of expertise in particle characterization and client collaboration, RJ Lee Group provides solutions for this problem. The company’s experts have developed an integrated modular approach called PC2 - Particle Contamination Control to detect and prevent particle contamination in production process.

PC2 - Particle Contamination Control

PC2’s modular approach provides suitable solution based on the type of industry and situation using its component modules.

PC2 Program Modules

PC2 program modules include:

Mitigation Planning

Root Cause: identifies the how and where the contaminant got into a process

Case Studies

Case study 1: Analysis Automation and Customized Reporting Provide the PC2 Solution

The issue was the catastrophic failure experienced in finished product and the root cause was particulate contamination found in a specific raw material. A screening process for particulate size and composition was required to prevent the use of contaminated powder.

RJ Lee Group recommended an automated SEM/EDS particulate characterization technique to solve the issue as it can provide the statistically significant data to meet the required criteria. The company created novel sample preparation methods to enable this automated technique. The huge amount of data generated by this analysis demanded a software solution capable of rapidly reducing the information. The company developed a package to set customized rules to instantly flag contaminant data and to create a mechanism capable of providing fail/pass summary reporting. This tailor-made information management system also facilitated assessment of overall pass/fail history per particular vendor or time of year.

Case study 2: Full Use of PC2 Program Mitigates Risk and Creates a Proactive Program

The issue was the presence of particle contamination in liquid product due to the shedding of process material into the product. What required was a program to monitor and classify contaminates found in the product.

For this issue, RJ Lee Group created a three tier strategy to detect root cause, create a monitoring program and make a library of reference materials to provide proactive investigation resolution. The company used various analytical techniques to determine the root cause, followed by physical characteristic evaluation utilizing simple, efficient analyses and then full characterization. Risk assessment identified and characterized likely contaminates to help any future root cause determinations. The monitoring program involved full characterization of particle types every year to ensure that there is no change in contaminates. The company created a completely customized solution that allowed contamination monitoring by material composition or physical property, trending contamination during specific production times, and identifying the origination of contaminates.


These case studies emphasize the modular approach of PC2 solution, which not only provides cost-efficient formula to identify root causes of contamination but also proposes measures to be taken for prevention of future contamination.
