In today’s analytical environment, water testing laboratories are under increasing pressure to deliver accurate, traceable, and audit-ready results. Whether testing drinking water, wastewater, industrial process water, or environmental samples, laboratories must demonstrate technical competency while meeting strict regulatory expectations.
This is where ERA water testing solutions have become a global benchmark.
As a trusted supplier of ERA products in Australia, Graham B Jackson (Graham B Jackson) supports laboratories with high-performance ERA-certified materials, proficiency testing programs, and laboratory quality solutions designed to improve analytical confidence and compliance.
The Growing Importance of Laboratory Quality Assurance
Water quality testing directly impacts public health, environmental safety, manufacturing processes, and regulatory compliance. Even advanced analytical instruments such as ICP-MS, GC-MS, TOC analysers, ion chromatography systems, and spectrophotometers require reliable calibration and validation standards to produce defensible results.
Without appropriate quality assurance measures, laboratories risk:
- Instrument drift
- Calibration errors
- False positives or negatives
- Failed accreditation audits
- Non-compliance penalties
- Poor inter-laboratory reproducibility
This is why Laboratory Quality Assurance programs increasingly depend on accredited certified reference material (CRM) and Proficiency Testing Studies.
According to the U.S. Environmental Protection Agency (EPA), laboratories conducting drinking water compliance testing must successfully participate in proficiency testing programs annually to maintain certification.
What Is ERA Water Testing?
ERA, part of Waters Corporation, is one of the world’s leading providers of environmental and purified water certified reference materials and proficiency testing products. Founded in 1977, ERA now supports thousands of laboratories across more than 80 countries.
At Graham B Jackson, we supply ERA water testing solutions to laboratories across Australia, helping organisations strengthen quality assurance, improve analytical accuracy, and support regulatory compliance in environmental and purified water testing applications.
ERA specialises in:
- Certified Reference Materials (CRMs)
- Proficiency Testing (PT) standards
- Custom analytical reference standards
- Environmental water testing solutions
- Regulatory compliance support
Their products are widely used in:
- Drinking water laboratories
- Wastewater treatment facilities
- Environmental monitoring labs
- Pharmaceutical manufacturing
- Food and beverage industries
- Industrial quality control laboratories
Why ERA Certified Materials Matter
A certified reference material acts as a scientifically validated benchmark used to verify analytical accuracy and traceability.
When laboratories use ERA-certified materials, they gain confidence that their methods, instruments, and analysts are producing reliable results.
ERA’s CRM portfolio supports testing for:
- Heavy metals
- PFAS compounds
- Nutrients
- Pesticides
- Organic contaminants
- TOC and turbidity
- Microbiological parameters
- Volatile compounds
These materials are manufactured under internationally recognised quality systems and include detailed Certificates of Analysis for full traceability.
Accreditation Builds Analytical Confidence
One of the strongest advantages of ERA water testing products is their accreditation framework.
Graham B Jackson maintains multiple globally recognised certifications, including:
- ISO/IEC 17025
- ISO/IEC 17034
- ISO/IEC 17043
- ISO 9001
These standards verify competence in testing laboratories, reference material production, and proficiency testing operations.
For laboratories pursuing or maintaining ISO/IEC 17025 accreditation, using accredited reference materials significantly strengthens audit readiness and data defensibility.
Understanding Proficiency Testing Studies
While certified reference materials validate instruments and methods internally, Proficiency Testing Studies evaluate how accurately a laboratory performs compared to peer laboratories.
In a typical PT study:
- Laboratories receive blind-coded samples
- Samples are analysed using routine methods
- Results are submitted to the PT provider
- Statistical performance reports are generated
- Laboratories compare performance against peer groups
Graham B Jackson proficiency testing programs help laboratories:
- Detect systematic analytical bias
- Identify training gaps
- Improve reproducibility
- Demonstrate competency to regulators
- Reduce accreditation risk
ERA’s PT systems are trusted globally because they provide detailed benchmarking and corrective action support.
Industry discussions among wastewater laboratories also consistently identify ERA as a long-term trusted PT provider for regulatory compliance programs.
Graham B Jackson’s Role in Environmental Water Testing
Environmental laboratories face increasingly complex testing demands, especially with emerging contaminants such as PFAS, pharmaceuticals, and ultra-trace metals.
Graham B Jackson supports these challenges through:
- Matrix-matched environmental standards
- Custom blended standards
- Low-level contaminant calibration solutions
- Rapid-response PT studies
- Specialised wastewater and groundwater programs
According to ERA Environmental Solutions, proficiency testing is considered a critical indicator of superior laboratory quality and regulatory competency.
ERA also develops over 1,000 custom standards annually, enabling laboratories to match exact analytes, matrices, and concentration ranges required for complex analytical workflows.
