Accurate water analysis starts with traceable standards. For Australian laboratories that perform environmental, process-water or drinking-water testing, ERA (Waters ERA) certified reference materials and era Proficiency Testing programs are widely used to prove method performance, quantify uncertainty and satisfy accreditation. Graham B Jackson Pty Ltd (GBJPL) is the authorised ERA partner in Australia, delivering ERA water CRMs, PT enrolment and local technical support so you get audit-ready results faster.
Why ERA CRMs matter (short, data-driven)
ERA has supplied proficiency testing (PT) and certified reference materials (CRMs) since 1977 and positions itself as a global specialist in environmental and water QA. Their CRMs and PT programs are covered by internationally recognised accreditations (examples include ISO/IEC 17025, ISO 17034 and ISO/IEC 17043), which directly supports traceability and the uncertainty statements many labs must submit during accreditation. Using accredited CRMs reduces calibration drift, gives defensible uncertainty budgets and strengthens audit outcomes.
ERA’s water expertise — what’s in the product toolbox
ERA’s environmental and process-water product lines include matrix-matched CRMs and standards for key water parameters (trace metals, nutrients, total organic carbon, conductivity, turbidity and more). Their product catalogues and environmental product pages show dedicated offerings for routine monitoring, wastewater, and industrial process water — making it straightforward to select ICP standard material and other water-specific CRMs that match your sample matrix and concentration range.
Proficiency testing (era Proficiency Testing) — more than a pass/fail
Proficiency testing is one of the strongest indicators of laboratory quality. ERA runs global PT schemes designed for environmental water programs and pairs those programs with web-based reporting and analytics (eDATA) so labs can rapidly evaluate performance, identify bias, and implement corrective actions. Regular participation in ERA PT programs supports ISO/IEC 17025 compliance and is commonly requested during regulator or audit reviews.
What ERA accreditation means for your uncertainty budget
Accredited CRMs arrive with a Certificate of Analysis (COA) that documents assigned values, measurement uncertainty and the traceability chain. ERA’s accreditations (and their globally recognised quality systems) mean those COAs can be used directly in a lab’s uncertainty budget and method validation paperwork — a practical advantage when preparing audit packs or responding to regulator queries. ERA maintain multiple facility accreditations internationally (US, UK, Ireland), reinforcing consistency across their product range.
Why Graham B Jackson Pty Ltd (GBJPL) as your Australian ERA partner matters
Buying CRMs from an overseas manufacturer can create logistical friction: customs paperwork, delayed COAs, or uncertain delivery windows. Graham B Jackson Pty Ltd (GBJPL) has supplied CRMs in Australia since 1982 and is listed as ERA’s Australian sales partner — combining ERA’s manufacturing credentials with local warehousing, import permits and technical support. That local presence simplifies ordering ERA-certified materials and helps labs meet tight audit timelines.
Practical, data-oriented steps for water labs
Map matrices and ranges. Identify your routine matrices (raw water, finished drinking water, effluent) and the concentration windows you analyse. Select ERA CRMs that are matrix-matched or closest in composition to reduce bias.
Use COAs in your uncertainty calculations. Incorporate the CRM assigned value and uncertainty from the ERA COA into your measurement uncertainty budget and method validation dossiers.
Enroll in ERA PT when possible. Choose PT studies aligned with your testing scope and use eDATA outputs to trend performance and demonstrate continual competence.
Ask about custom or specialist CRMs. ERA offers bespoke solutions for unusual matrices or concentrations; Graham B Jackson Pty Ltd (GBJPL) can coordinate requests to shorten lead times and ensure correct documentation.
Use case examples where ERA CRMs add measurable value
Municipal and drinking-water labs: matrix-matched standards for low-ppb metals and nutrient reporting.
Industrial/process water: turbidity, conductivity and TOC standards for in-process verification and instrument validation.
Environmental monitoring: PT participation combined with CRMs for soils, sediments and water to demonstrate long-term method performance.
ERA’s long history, multiple international accreditations, broad environmental product range and linked PT programs make their CRMs a reliable backbone for water QA programs. Partnering with Graham B Jackson Pty Ltd (GBJPL)means Australian labs can access ERA certified materials with local support, complete documentation and practical supply-chain advantages. If you’re planning an audit, upgrading your uncertainty budget, or building a PT calendar, Graham B Jackson Pty Ltd (GBJPL) can help match ERA CRMs and PT schemes to your exact needs.
