Laboratory Accreditation and Quality Assurance Strengthening the PFAS Testing Market

Reliable Testing Requires Strong Laboratory Standards

PFAS analysis is a technically demanding activity that requires specialized equipment, trained personnel, and carefully controlled laboratory procedures.

Environmental agencies, industrial customers, and water utilities depend on analytical results to make decisions involving contamination, compliance, and environmental management.

The reliability of these results is therefore central to the PFAS testing market, creating opportunities for laboratories that maintain strong quality systems and appropriate technical capabilities.

Accreditation Builds Confidence in Analytical Results

Laboratory accreditation provides an independent framework for evaluating technical competence and quality management.

Accredited laboratories typically demonstrate compliance with applicable requirements involving personnel, equipment, analytical procedures, documentation, and quality assurance.

For customers, accreditation can provide additional confidence that testing activities follow recognized standards.

However, accreditation alone does not mean every analytical method or sample type is automatically covered. Laboratories must verify that their accreditation scope includes the relevant testing activities.

Method Validation Supports Analytical Accuracy

PFAS testing methods must be evaluated according to their intended applications.

Method validation can involve assessing analytical sensitivity, precision, accuracy, selectivity, recovery, and other relevant performance characteristics.

Laboratories also need to determine whether methods are suitable for particular sample matrices.

Drinking water, wastewater, soil, and food may require different analytical procedures.

Appropriate validation helps ensure that results are meaningful and defensible.

Contamination Prevention Is Essential

PFAS contamination can occur during sample collection, transportation, preparation, or analysis.

Certain laboratory materials and environmental sources may introduce background contamination.

Testing facilities therefore implement procedures designed to minimize contamination risks.

These measures may include suitable sampling equipment, carefully selected laboratory materials, procedural blanks, and controlled handling practices.

Contamination prevention is especially important when laboratories analyze samples containing very low concentrations of PFAS.

According to a recent report by Market Research Future, technological developments and growing testing requirements are influencing the capabilities and competitive landscape of PFAS analytical services.

Quality Control Supports Consistent Performance

Laboratories use quality-control procedures to monitor analytical performance.

Common activities may include calibration verification, blank analysis, recovery checks, duplicate testing, and reference material evaluation.

These procedures help identify analytical problems and support consistency across sample batches.

Laboratory information management systems can also improve documentation and traceability.

Opportunities for Quality-Focused Laboratories

Testing providers can differentiate themselves through dependable analytical services.

Customers may value laboratories that offer:

• Appropriate accreditation.

• Reliable analytical methods.

• Transparent reporting.

• Strong quality management.

• Experienced technical personnel.

• Effective sample tracking.

• Consistent turnaround times.

These capabilities can support long-term partnerships with industrial and environmental customers.

Challenges in Maintaining Quality

Quality assurance requires continuous investment.

Laboratories must maintain equipment, train personnel, update analytical procedures, and monitor changing requirements.

Specialized instruments can involve substantial operating expenses.

Staff shortages or increasing sample volumes may also create operational pressures.
