In elemental analysis, precision is everything. Whether testing drinking water, pharmaceutical products, mining samples, food, or industrial materials, laboratories rely on accurate analytical data to support quality control, regulatory compliance, and scientific research. However, even the most advanced instruments are only as reliable as the standards used to calibrate and verify them.
This is why ICP standards and Certified Reference Materials (CRMs) are indispensable in modern analytical laboratories. They provide the traceability, consistency, and confidence required for accurate measurements using techniques such as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
At Graham B. Jackson (GBJ), we supply high-quality Certified Reference Materials and standards for ICP analysis from globally recognised manufacturers, helping Australian laboratories achieve dependable analytical performance across a wide range of industries.
Why ICP Standards Are Essential
ICP-OES and ICP-MS are among the world’s most widely used elemental analysis techniques because they offer exceptional sensitivity and multi-element capability. These techniques are routinely used to detect trace metals at concentrations ranging from parts per million (ppm) to parts per trillion (ppt).
However, achieving reliable results depends on properly prepared ICP standards.
ICP standards are used to:
- Calibrate analytical instruments
- Verify calibration accuracy
- Validate analytical methods
- Monitor instrument stability
- Detect calibration drift
- Support quality assurance programmes
Without properly characterised standards, analytical results may become inaccurate, leading to incorrect conclusions, failed audits, or costly production errors.
The Role of Certified Reference Materials
While calibration standards establish instrument response, Certified Reference Materials (CRMs) verify the accuracy of the complete analytical process.
CRMs are extensively characterised materials accompanied by documentation that includes:
- Certified values
- Measurement uncertainty
- Metrological traceability
- Storage recommendations
- Expiry information
Unlike routine laboratory standards, certified reference materials undergo rigorous homogeneity testing and stability studies, providing laboratories with greater confidence in their analytical results.
They are widely used for:
- Method validation
- Instrument performance verification
- Quality control
- Proficiency testing
- Laboratory accreditation
- Regulatory compliance
Many laboratories accredited to ISO/IEC 17025 incorporate CRMs into routine testing programmes to demonstrate analytical competence and measurement traceability.
Standards for ICP Analysis: Choosing the Right Solution
Selecting appropriate standards for ICP analysis depends on several factors.
Match the Analytical Matrix
Choose standards that closely resemble the sample matrix whenever possible, whether analysing:
- Drinking water
- Wastewater
- Soil
- Geological samples
- Food products
- Pharmaceuticals
- Industrial chemicals
Matrix-matched standards minimise analytical bias and improve measurement accuracy.
Select Appropriate Concentrations
Calibration standards should bracket the expected concentration range of the samples being analysed.
Verify Elemental Composition
Ensure standards contain the required analytes at certified concentrations suitable for your analytical method.
Maintain Traceability
Always use standards produced under recognised quality systems with documented traceability to national or international measurement standards.
Why Laboratories Depend on Certified Reference Material Suppliers
Not all laboratory standards provide the same level of confidence. Reliable certified reference material suppliers invest heavily in manufacturing processes, quality control, and analytical verification to ensure every product meets strict international requirements.
Choosing an experienced supplier provides laboratories with:
- Consistent product quality
- Comprehensive documentation
- Reliable technical support
- Batch-to-batch consistency
- Traceable certified values
- Confidence during audits and accreditation
These benefits are particularly important in regulated industries where analytical accuracy directly affects compliance and product quality.
Understanding the CPAChem Certificate of Analysis
Every high-quality reference material should be accompanied by comprehensive documentation. One important example is the CPAChem Certificate of Analysis (CoA).
A CPAChem certificate of analysis typically includes:
- Product identification
- Certified concentration values
- Measurement uncertainty
- Lot number
- Expiry date
- Storage recommendations
- Traceability information
- Quality assurance details
This documentation enables laboratories to demonstrate full traceability while supporting internal quality systems and external audits.
Reviewing the Certificate of Analysis before use helps laboratories verify that the reference material meets the requirements of the intended analytical application.
