Environmental testing laboratories face increasing pressure to deliver accurate, traceable, and defensible results. Whether assessing soil contamination, monitoring drinking water quality, or supporting environmental compliance programs, analytical data drives critical decisions that impact public health, agriculture, industry, and the environment.
The foundation of reliable testing lies in the use of a high-quality certified reference material (CRM).
From CRM soil testing applications to advanced-era water testing programs, certified reference materials help laboratories verify analytical performance, maintain compliance, and ensure confidence in reported results. As a trusted supplier of ERA products, Graham B Jackson provides laboratories across Australia and New Zealand with access to internationally recognised certified reference materials designed to support environmental excellence.
What Is a Certified Reference Material?
A certified reference material is a highly characterised material accompanied by a certificate that provides certified values, measurement uncertainty, and traceability information.
These materials serve as analytical benchmarks, allowing laboratories to compare test results against known values and verify the accuracy of their methods.
Certified reference materials are commonly used to:
- Validate analytical methods
- Verify instrument calibration
- Assess measurement uncertainty
- Monitor laboratory performance
- Support ISO/IEC 17025 accreditation
- Demonstrate data traceability
Without reliable reference standards, laboratories risk producing inaccurate results that may lead to compliance issues, environmental risks, and costly retesting.
The Growing Importance of CRM Soil Testing
Soil testing plays a critical role in agriculture, mining, environmental monitoring, and land remediation projects.
Laboratories routinely analyse soils for:
- Heavy metals
- Nutrients
- Organic contaminants
- PFAS compounds
- Salinity
- pH and soil chemistry indicators
Accurate soil analysis is essential because environmental decisions often depend on small differences in concentration levels. Regulatory thresholds for contaminants such as lead, arsenic, cadmium, and mercury require laboratories to maintain exceptional analytical precision.
CRM soil testing provides laboratories with a proven method for validating analytical performance. By testing certified soil reference materials alongside routine samples, laboratories can confirm that methods are performing as expected and identify potential errors before results are reported.
This process strengthens confidence in environmental assessments, remediation projects, and agricultural management decisions.
Why Era Water Testing Relies on Certified Standards
Water quality testing is equally dependent on analytical accuracy.
According to global health organisations, contaminated drinking water remains one of the leading environmental risks to public health, making reliable testing a critical component of water safety programs.
Modern-era water testing programs use certified reference materials to evaluate the accuracy of analytical methods used for:
- Drinking water monitoring
- Wastewater analysis
- Groundwater assessments
- Surface water testing
- Industrial water treatment
- Environmental compliance reporting
ERA has built a global reputation for producing certified reference materials and proficiency testing solutions that support water laboratories in maintaining data quality and regulatory compliance.
By incorporating ERA standards into routine quality control programs, laboratories can verify analytical performance and ensure that reported results are both accurate and defensible.
Supporting ISO 17025 and Laboratory Accreditation
Accredited laboratories are expected to demonstrate ongoing confidence in their analytical processes.
Under ISO/IEC 17025 requirements, laboratories must validate methods, verify performance, and maintain traceability throughout the testing process.
Certified reference materials support these objectives by helping laboratories:
Verify Method Accuracy
CRMs provide an independent benchmark against which analytical methods can be evaluated.
Monitor Long-Term Performance
Routine CRM analysis helps identify trends, bias, or instrument drift before they impact customer results.
Improve Audit Readiness
Traceable reference standards provide documented evidence of quality control during accreditation assessments and regulatory inspections.
Strengthen Data Integrity
Using certified materials increases confidence that reported results accurately reflect sample composition.
