Accurate analytical data underpins every decision in environmental monitoring, mining, water quality assessment, and industrial quality control. Whether a laboratory is validating soil contamination levels, verifying potable water safety, or analysing mineral composition, the reliability of results depends on one critical component: Certified Reference Materials (CRMs).
At Graham B Jackson(GBJ), we provide LGC Standards certified reference material to laboratories across Australia, enabling precise calibration, method validation, and regulatory compliance across a wide range of applications, including CRM soil testing, ERA water testing, certified reference ores, and NCS reference materials.
Why Certified Reference Materials Matter
CRMs are not ordinary test materials. They are rigorously characterised, traceable to recognised standards, and supplied with detailed Certificates of Analysis (CoAs). These certificates define certified values, measurement uncertainty, homogeneity, and stability—making CRMs essential for:
- Instrument calibration
- Method validation and verification
- Quality control and proficiency testing
- Audit and regulatory defensibility
Without CRMs, analytical data lacks the traceability and confidence required by ISO, environmental regulators, and accreditation bodies.
LGC Standards: A Global Authority in Reference Materials
LGC Standards is one of the world’s most respected producers and distributors of reference materials, serving environmental, pharmaceutical, food, forensic, and geochemical laboratories globally. With decades of expertise, LGC provides CRMs that support compliance with ISO/IEC 17025, ISO 17034, and international regulatory frameworks.
Through Graham B Jackson(GBJ), Australian laboratories gain access to LGC’s extensive portfolio, including ERA water testing standards, certified reference ores, and internationally recognised NCS reference materials.
CRM Soil Testing: Accurate Assessment of Environmental Risk
Soil testing laboratories face increasing regulatory scrutiny, particularly for heavy metals, nutrients, and contaminants in agricultural, industrial, and remediation projects. CRM soil testing materials are essential to verify analytical accuracy across diverse and complex soil matrices.
LGC soil CRMs are characterised for parameters such as:
- Trace metals (As, Cd, Pb, Hg, Cr, Ni)
- Major and minor elements
- Nutrients and selected organic contaminants
Using matrix-matched soil CRMs helps laboratories:
- Validate digestion and extraction methods
- Improve recovery and reproducibility
- Demonstrate compliance during environmental audits
This is particularly important when results influence land-use decisions or remediation strategies.
ERA Water Testing: Trusted Standards for Water Quality Laboratories
ERA® water testing standards, part of the LGC portfolio, are widely used for quality control in drinking water, wastewater, and environmental water analysis. ERA standards are designed to simulate real-world samples and are commonly used for:
- Routine QC checks
- Proficiency testing and performance evaluation
- Instrument and method verification
ERA water testing CRM support parameters, including:
- Trace metals
- Nutrients
- Inorganic ions
- Select organic contaminants
Because water testing often involves reporting at very low regulatory limits, the stability, homogeneity, and uncertainty documentation of ERA standards are critical to maintaining confidence in reported data.
Certified Reference Ores: Essential for Mining and Geochemical Analysis
Mining, exploration, and metallurgical laboratories rely on certified reference ores to ensure accurate elemental analysis of geological samples. Small analytical errors can significantly impact resource estimation, process optimisation, and commercial decisions.
LGC-certified reference ores are developed from well-characterised geological materials and are used to:
- Validate XRF, ICP-OES, and ICP-MS methods
- Monitor analytical drift over time
- Ensure comparability between laboratories and instruments
These CRMs cover a wide range of matrices and elements, supporting base metals, precious metals, and multi-element ore analysis.
NCS Reference Materials: Internationally Recognised Accuracy
NCS reference materials (China National Analysis Centre for Iron & Steel) are globally recognised CRMs used extensively in metallurgical, geological, and environmental laboratories. Distributed through LGC Standards, NCS reference materials are valued for:
- Robust certification processes
- International traceability
- Wide coverage of metals, ores, and industrial materials
For laboratories engaged in comparative studies or international projects, NCS reference materials support harmonisation of analytical results across borders.
Data-Driven Documentation and Traceability
A key strength of LGC Standards CRMs is the depth of technical documentation. Certificates of Analysis typically include:
- Certified values with expanded uncertainty
- Detailed characterisation methodology
- Homogeneity and stability assessments
- Guidance on storage and usage
This level of transparency supports defensible results in regulatory inspections, third-party audits, and accreditation assessments.
