Selecting the right reference material is critical for accurate, compliant analytical work. Consider the following factors when choosing Merck CRMs:
Q1: What level of certification is required for my application?
For regulated environments (e.g., pharma, environmental analysis), always select ISO 17034/ISO 17025 certified CRMs with NIST traceability, like Certipur® and matrix CRMs.
Q2: How do I verify traceability and batch quality?
All Merck CRMs are delivered with a COA specifying certified values, measurement uncertainty, lot number, and expiry date. Certificates are available for download from the Merck website for audit readiness.
Q3: Are Merck CRMs compatible with my analytical method?
Whether you use AAS, ICP-OES, ICP-MS, HPLC, or titration, Merck provides detailed method compatibility and instructions for each product. Contact technical support for method-specific advice.
Q4: How should I store and handle reference materials?
Follow the handling and storage instructions on the COA. Many solutions should be stored at 2–8°C, protected from light and contamination to ensure long-term stability.
By prioritizing certified, traceable materials from Merck, you ensure not only method accuracy but also full compliance with industry and regulatory requirements.
