Regulatory programs and customer audits don’t just ask for “good data”—they expect defensible data. That’s why Graham B Jackson Pty Ltd (GBJPL) now supplies ERA certified materials and ERA Proficiency Testing (PT) programs in Australia, giving environmental and process-water labs a proven route to traceable calibration and objective performance checks. ERA (a Waters company) has supported environmental testing since 1977 and today serves labs worldwide with ISO-accredited PT and ERA Life Sciences Certified Reference Materials as well.
Who is ERA and why does accreditation matter?
ERA is part of Waters Corporation and operates globally with accreditations that align with how NATA and international assessors evaluate quality systems: ISO/IEC 17043 for proficiency testing providers, ISO 17034 for certified reference material production, and ISO/IEC 17025 for testing. ERA highlights these accreditations across its program documentation and explains how they underpin confidence in reported values.
ERA’s U.S. facility is accredited by A2LA to ISO 17025, 17034 and 17043, and its Ireland facility is accredited by INAB to ISO 17025 and 17034—alongside ISO 9001 registrations—supporting global acceptance of both era water testing PT results and CRMs.
What Australian water labs can source via Graham B Jackson Pty Ltd (GBJPL)
Graham B Jackson Pty Ltd (GBJPL) is listed by ERA as the Australian sales partner, providing local quotations, import compliance and technical matching. That means you can procure ERA water PT studies and ICP standard material in Australia quickly, with documentation ready for audits.
Environmental & process-water CRMs (ready-to-use)
Low-level CRMs in synthetic drinking/wastewater matrices—ideal for method development, system checks and routine QC without time-consuming dilution.
Process water / ultrapure water programs for facilities that must verify extremely low background levels across ionic, organic and particulate contaminants.
These cpachem testing Australia keywords aren’t relevant here, but your focus term “era water testing” applies: ERA’s environmental portfolio covers drinking water, wastewater, ground water and pollution studies with matching CRMs and PT options.
Life sciences & pharma
Many Australian labs straddle utilities and GxP. ERA also supplies Life Sciences Certified Reference Materials for process water in pharma and precision manufacturing environments—useful when a site quality system must harmonise environmental and GxP testing under one supplier.
Custom reference standards—fast
When a standard method doesn’t fit, ERA can manufacture custom CRMs in as little as five business days (complex projects may take longer). Graham B Jackson Pty Ltd (GBJPL) coordinates the specification (analytes, acids/matrix, concentration levels, bottle sizes) and delivery.
ERA Proficiency Testing: frequency, speed and coverage
External PT is a cornerstone of ISO/IEC 17025 accreditation. ERA runs frequent water PT studies across the calendar, so you can align participation with audit cycles and staffing constraints.
Speed matters after submission. ERA promotes two-business-day reporting on many programs, helping labs close corrective actions and keep accreditation on track. (This fast turnaround is also noted in historical coverage of ERA’s PT operations.)For industrial dischargers and contract labs tied to U.S. regulatory customers, ERA supports the EPA’s DMR-QA program—useful if your Australian site participates in multinational QA schemes or benchmarks performance against U.S. affiliates.
CRM vs PT—how they work together
ERA provides both:
CRMs certified under ISO 17034/17025 for calibration, trueness checks and method validation—what you use every day to ensure the instrument is reading correctly.
PT under ISO/IEC 17043 to independently demonstrate competence—what you use periodically to prove the whole process works under blind conditions.
Using era certified materials (CRMs) to lock in traceability, then confirming performance via ERA Proficiency Testing, is the most efficient path to defensible data—and it’s the approach auditors expect to see.
Practical wins we see in Australian labs
Reduced prep time & risk
Low-level, matrix-matched CRMs minimise on-bench dilutions and the error that comes with them—especially at sub-ppb levels. Labs report smoother verifications and fewer repeats.
Faster accreditation responses
Frequent PT windows plus rapid grading compress the time from “action required” to “closed,” protecting accreditation status and client SLAs.
Clear audit trail
ERA’s documentation packages (CoAs, SDS, program instructions) are centralised, which simplifies internal QA reviews and external assessments.
Choosing the right ERA products with Graham B Jackson Pty Ltd (GBJPL)
Step 1 — Define the decision.
Routine compliance? Start with standard era water testing PT studies mapped to your permit or method set and stock CRMs that match your analytes/matrices.
Step 2 — Match matrix & range.
Pick CRMs that mirror your sample matrix (drinking water, wastewater, process water) and concentration range (e.g., low-level CRMs for trace metals by ICP-MS).
Step 3 — Plan the calendar.
Book PT from ERA’s schedule to align with NATA surveillance audits and internal QA reviews; keep a standing cadence for critical analytes.
Step 4 — Custom where it counts.
Use custom ERA certified materials for non-standard matrices or combined analyte sets to eliminate error-prone multi-supplier blending.
