In today’s regulatory and quality-centric world, precision in analytical water testing is non-negotiable. Whether you’re a municipal laboratory, industrial facility, or environmental consultancy, data accuracy isn’t just a best practice — it’s a regulatory requirement. That’s where ERA Life Sciences Certified Reference Materials and ERA Proficiency Testing standards, distributed by Graham B Jackson (GBJ), become indispensable assets for any water testing program.
At GBJ, we help laboratories and quality departments in Australia and beyond integrate ERA’s globally respected CRM water testing solutions to strengthen analytical credibility, ensure compliance, and improve overall confidence in decision-making based on water quality data.
Why Precision Matters in Water Testing
Water quality data directly influences public health decisions, environmental protection strategies, industrial process validation, and regulatory compliance. Instruments like ICP-OES, GC-MS, TOC analysers, ion chromatography, and spectrophotometers are only as reliable as the standards used to calibrate and verify their performance. Without accurate calibration and method validation, even state-of-the-art equipment can produce biased or inconsistent results.
Certified Reference Materials (CRMs) provide that benchmark for accuracy. Unlike regular laboratory reagents, CRMs come with metrologically traceable values, uncertainties, and documented certificates of analysis that meet international norms — making them essential for defensible results.
ERA: A Global Leader in CRM Water Testing & Proficiency Programs
Waters ERA (often referred to simply as ERA) has been at the forefront of analytical quality assurance since 1977. Today, ERA serves thousands of laboratories in over 80 countries, providing one of the most comprehensive suites of certified reference materials and proficiency testing programs in the world.
ERA’s solutions are tailored to support multiple applications — from environmental compliance and industrial water analysis to life sciences and pharmaceutical quality programs. Their products are engineered to deliver reliable data with global acceptance, backed by robust accreditation and independent quality assurance.
What Makes ERA Certified Materials Stand Out?
1. Internationally Recognised Accreditations
ERA’s CRMs and PT schemes are backed by some of the most stringent global accreditation standards:
- ISO/IEC 17034:2016 – Ensures competence in producing certified reference materials.
- ISO/IEC 17025:2017 – Demonstrates technical proficiency of testing and calibration laboratories.
- ISO/IEC 17043:2023 – Governs proficiency testing providers.
- ISO 9001:2015 – Quality management assurance across operations.
These accreditations verify that every CRM is produced, analysed, and documented according to internationally accepted principles — giving laboratories confidence in traceability and result defensibility.
The Role of CRMs in Water Testing
Certified Reference Materials are not mere calibration standards — they are cornerstones of quality assurance. Their roles include:
Calibration and Traceability: CRMs ensure that analytical instruments are calibrated to internationally traceable standards, reducing bias and systematic error in test results.
Method Validation: Before introducing new analytical methods into routine use, CRMs help verify accuracy and precision across measurement ranges.
Quality Control: Regular use of CRMs in internal QC programs helps laboratories detect drift or anomalies over time.
Accreditation Support: Many regulatory bodies and accreditation schemes, including NATA and ISO/IEC 17025, require or strongly recommend CRM use to establish metrological traceability and method integrity.
Comprehensive CRM Water Testing Solutions
ERA’s CRM portfolio for water quality is expansive, covering organic and inorganic analytes across ultra-pure, drinking, wastewater, and environmental matrices. Examples include:
| Application | Analytes / Parameters | Typical Methods |
| Drinking & Purified Water | Conductivity, TOC, Turbidity | Spectrophotometry, TOC Analysers |
| Environmental / Wastewater | Nutrients, BOD, COD, Metals | Ion Chromatography, ICP-MS |
| Trace Metals | Lead, Mercury, Arsenic | ICP-OES, ICP-MS |
| Microbiology | E. coli, Total Coliforms | Membrane Filtration, MPN |
These CRMs come with detailed certificates of analysis noting assigned values, uncertainties, and traceability — essential documentation for compliance, audits, and reporting.
ERA Proficiency Testing: Benchmarking Your Lab’s Performance
Beyond CRMs, ERA Proficiency Testing (PT) programs allow labs to measure their performance against peer groups and established standards. Through periodic inter-laboratory assessments, PT provides invaluable insights into analytical competency, method reliability, and areas requiring corrective action.
PT participation also supports accreditation bodies’ requirements that laboratories demonstrate ongoing performance verification. The associated reports and trend data become strategic tools for quality improvement and risk mitigation.
