Description
Verify Real-World Handheld XRF Performance with the SdAR-M2 Soil Certified Reference Material
The SdAR-M2 Soil Certified Reference Material (CRM) is an ideal quality control standard for professionals who perform routine handheld XRF analysis on environmental soils, mining samples, and geochemical materials. Representing a moderately contaminated soil matrix, SdAR-M2 bridges the gap between background soils and highly contaminated reference materials, making it one of the most practical CRMs for everyday instrument verification.
Whether you're conducting Phase II Environmental Site Assessments (ESAs), brownfield investigations, mining exploration, industrial compliance testing, or laboratory quality assurance, SdAR-M2 helps verify that your handheld XRF continues to deliver accurate and repeatable analytical results.
Unlike extremely low- or high-concentration standards, SdAR-M2 closely reflects the elemental concentrations encountered during many real-world environmental investigations, making it an excellent choice for daily quality control.
Alloy Geek supplies genuine SdAR-M2 Certified Reference Material packaged for convenient laboratory and field use.
Why Choose SdAR-M2?
Not every quality control sample needs to represent pristine soil or heavily contaminated waste. Most handheld XRF projects fall somewhere in between.
SdAR-M2 was developed to represent a moderate concentration soil matrix, allowing users to verify instrument performance where many environmental action levels, remediation projects, and mining samples are routinely encountered.
For many handheld XRF operators, this makes SdAR-M2 the CRM that spends the most time on the workbench.
Typical Applications
SdAR-M2 is commonly used for:
- Daily handheld XRF quality control
- Environmental consulting
- Brownfield investigations
- Phase II Environmental Site Assessments (ESAs)
- Mining and mineral exploration
- Geochemical analysis
- Instrument performance verification
- Calibration verification
- Laboratory QA/QC programs
- Government and regulatory testing
- University research
- Training and operator qualification
Compatible Handheld XRF Analyzers
SdAR-M2 is compatible with virtually every modern handheld XRF analyzer designed for environmental, mining, and soil analysis.
Why Use a Certified Reference Material?
Quality assurance begins with confidence in your measurements.
Using a Certified Reference Material allows you to verify that your handheld XRF continues producing results within expected limits before valuable field time is lost or analytical data becomes questionable.
Routine verification can help identify:
- Instrument drift
- Detector contamination
- X-ray tube aging
- Calibration changes
- Operator inconsistencies
- Unexpected analytical bias
Many organizations incorporate CRM testing into their standard operating procedures and ISO-compliant quality management systems.

Frequently Asked Questions
Is SdAR-M2 a Certified Reference Material?
Yes. SdAR-M2 is a Certified Reference Material (CRM) with certified elemental concentrations and documented uncertainties, making it suitable for professional quality assurance, calibration verification, and method validation.
Why choose SdAR-M2 instead of SdAR-L2 or SdAR-H1?
SdAR-M2 represents a moderate-concentration soil matrix that closely reflects many routine environmental and mining samples. It is an excellent choice for everyday quality control, while SdAR-L2 is better suited for low-level verification and SdAR-H1 is intended for high-concentration contaminated soils.
Can I use SdAR-M2 to calibrate my handheld XRF?
SdAR-M2 is primarily intended for calibration verification, instrument quality control, and analytical method validation. Users developing custom calibrations should follow their instrument manufacturer's recommended procedures.
Is the Certificate of Analysis included?
Yes. Every SdAR-M2 purchased from Alloy Geek includes the official digital Certificate of Analysis containing certified concentrations and associated uncertainties.
