Custom Reference Materials
& Matrix-Matched Standards
Alpha Prime Lab supports the sourcing and development of Custom Reference Materials, Custom Standards, Matrix-Matched Standards and hard-to-find reference materials for laboratories where standard catalog products do not adequately match the real sample matrix, concentration range, analytical method or quality requirement.
When a standard reference material does not fit the real application.
A catalog reference material may contain the correct analyte but still be technically unsuitable because the matrix, concentration, physical form, preparation route or intended analytical use is different from the real sample.
This matters because calibration, method validation and routine quality control are only as meaningful as the relationship between the reference material and the analytical problem being evaluated.
The available CRM or RM does not sufficiently represent the real sample matrix.
The certified or assigned values fall outside the required calibration or verification range.
A previously used standard may no longer be available or practical to source.
The application needs an unusual analyte combination, material form, preparation route or documentation set.
A technically weak match can reduce confidence in calibration, validation, QC and verification activities.
Custom and specialized standards
for real analytical requirements.
Depending on the analytical need, the most appropriate route may be an existing CRM, a hard-to-find standard from another manufacturer, a matrix-matched standard or a newly developed custom reference material.
Custom Reference Materials
Reference materials developed around specified matrix, analytes, concentration range, form and intended analytical use.
Matrix-Matched Standards
Standards designed to more closely represent the composition or physical characteristics of the real sample matrix.
Hard-to-Find Reference Materials
Technical sourcing across global manufacturers when common distributors or catalog searches do not produce a suitable option.
Calibration & QC Standards
Specialized standards for instrument calibration, method validation, verification, routine QC and performance monitoring.
Custom does not always mean better. It means closer to the real requirement when necessary.
If an existing catalog CRM or RM is technically suitable, it may remain the most efficient option. A custom or matrix-matched route becomes relevant when standard materials cannot adequately support the measurement objective.
The sample matrix has a strong effect on analytical response.
Especially relevant in XRF, NIR and matrix-sensitive analytical workflows.
The required concentration range is not available in standard products.
Custom values or a dedicated calibration range may be needed.
The required analyte combination is uncommon or application-specific.
Standard single-analyte or multi-element products may not match the real need.
The preferred standard is discontinued, unavailable or impractical to source.
An alternative manufacturer or custom route may provide a better technical path.
Custom reference materials
across analytical techniques.
Custom and matrix-matched reference materials can support analytical workflows where calibration quality, matrix similarity and application-specific confidence are important.
XRF Calibration Standards
Calibration and validation materials for metals, ores, cement, geological samples, industrial products and pressed-pellet or fusion-bead workflows.
ICP-OES & ICP-MS Standards
Single-element, multi-element and application-specific standards for major, minor and trace-element analysis across industrial, environmental and research applications.
NIR Calibration Samples
Reference samples for calibration-model development, validation and ongoing performance verification in food, agriculture, chemical and process applications.
Method Validation & Quality Control
Reference standards for validation, routine QC, instrument verification, accuracy checks and laboratory-quality assurance activities.
The quality of the custom standard begins with the quality of the specification.
The more clearly the matrix, analytes, concentration range, analytical technique and intended use are defined, the more effectively a custom or matrix-matched reference-material route can be evaluated.
Material type, product, ore, alloy, soil, cement, battery material, food or another matrix.
Elements, compounds, contaminants or properties that need assigned or certified values.
Target values, tolerance, calibration points or range required for the analytical method.
XRF, ICP-OES, ICP-MS, OES, AA, NIR or another measurement technique.
Calibration, method validation, quality control, verification, method development or research.
Required certificate, uncertainty, traceability, homogeneity, stability or other technical documentation.
Which type of reference material
fits the application?
The appropriate reference material depends on the analytical objective, documentation requirement, sample matrix and degree of technical matching required.
| Reference Material Type | Best Suited For | Typical Applications | Key Consideration |
|---|---|---|---|
| Catalog Standard | General applications where a technically suitable product is already available. | Routine calibration, general QC, verification. | Fastest route when matrix, range and intended use already match. |
| Certified Reference Material (CRM) | Applications requiring documented certified values, uncertainty and traceability. | Method validation, QA/QC, audit, accreditation support. | Certification scope and intended use must still fit the method. |
| Matrix-Matched Standard | Applications where matrix effects materially influence analytical response. | Ore CRM, soil CRM, cement, metals, XRF and NIR. | Similarity to the real matrix may be more important than product familiarity. |
| Custom Reference Material | Specialized applications where existing products are technically inadequate. | XRF calibration, ICP standards, NIR samples, industrial R&D. | Requires clear specification, feasibility review and appropriate development route. |
Specialized reference-material support
across industries.
Custom or matrix-matched standards may be relevant wherever the real sample cannot be represented adequately by a conventional catalog product.
From technical requirement
to sourcing or custom development.
Every request begins with the analytical objective. We then determine whether an existing product, alternative manufacturer, matrix-matched option or custom-development route is the most appropriate path.
Submit the Requirement
Provide matrix, analytes, concentration range, instrument, method, intended use and documentation needs.
Technical Review
We assess whether an existing RM/CRM can meet the need or whether a custom route should be evaluated.
Feasibility & Matching
Potential manufacturers, specialist laboratories, material sources and development routes are reviewed.
Solution Proposal
We provide the proposed technical route, quotation, expected lead time and documentation scope.
Production / Sourcing
We coordinate the selected manufacturer or laboratory and track technical and quality requirements.
Delivery & Technical Support
The material is delivered with relevant documentation and application-oriented technical guidance where required.
Custom-standard sourcing should begin with the analytical problem.
Our role is to help define the real requirement first, then identify the most technically suitable route — whether that is an existing CRM, a hard-to-find standard, a matrix-matched product or a custom development project.
Matrix, analytes, range, method, instrument, intended use and documentation are considered together.
We do not assume custom development is necessary before checking technically suitable alternatives.
The objective is technical suitability for the real analytical application rather than similarity in product description.
Manufacturer communication, documentation and lead-time tracking are coordinated through the project.
Support can extend into sample preparation, analytical instruments, proficiency testing and laboratory setup.
Frequently asked questions about
Custom Reference Materials.
These answers provide a practical starting point. Final suitability always depends on the specific analytical method, matrix and intended use.
What is a Custom Reference Material?
A Custom Reference Material is a reference material developed around a defined technical requirement such as matrix, analytes, concentration range, physical form, analytical technique or intended use.
When should a custom or matrix-matched standard be considered?
It may be appropriate when existing catalog standards do not adequately match the real matrix, concentration range, analyte combination, material form or analytical objective.
Does every custom standard become a Certified Reference Material?
No. A custom material, matrix-matched standard and Certified Reference Material are not automatically equivalent. The available certification, uncertainty, traceability and documentation depend on the selected development route and provider.
What information is needed to evaluate feasibility?
Useful information includes the sample matrix, target analytes, concentration range, analytical method, instrument technique, intended use, required quantity and documentation expectations.
Can Alpha Prime Lab help with hard-to-find standards before developing a custom one?
Yes. The technical review can include searching alternative manufacturers and specialist sources before recommending a custom-development route.
Can custom standards support XRF, ICP-OES, ICP-MS and NIR applications?
Yes, depending on feasibility and the technical requirement. These are common application areas for matrix-matched, calibration or custom reference-material projects.
Cannot find a reference material that fits the real sample?
Send us your sample matrix, target analytes, concentration range, analytical method, instrument and intended use. Alpha Prime Lab can help evaluate whether an existing CRM, alternative reference material, matrix-matched standard or custom-development route is the most appropriate technical option.
