Product Overview
The Sodium, 1000 ppm ICP-ML single-element standard is a high-purity solution engineered for inductively coupled plasma-mass spectrometry (ICP-MS) applications. Formulated with ultra-low matrix interference, this standard ensures exceptional accuracy in trace sodium quantification, making it indispensable for laboratories requiring stringent analytical precision. The solution is stabilized to prevent precipitation or degradation over time, guaranteeing long-term reliability in calibration curves and routine quality control procedures. Each batch undergoes rigorous testing to confirm concentration accuracy, with traceability to NIST or equivalent reference materials. The liquid form allows for seamless integration into automated sample preparation workflows, minimizing handling errors. Designed for compatibility with most ICP-MS instruments, this standard eliminates the need for complex dilutions while maintaining linear response across a broad dynamic range. Its low background contamination levels make it particularly suitable for environmental, pharmaceutical, and food safety testing where sodium detection at trace levels is critical. The solution comes in a high-density polyethylene bottle with tamper-evident sealing to preserve integrity during storage and transport.
FAQs
1. What is the shelf life of this sodium ICP standard when stored properly?
When stored unopened at room temperature in its original container, this standard maintains its specified concentration for 24 months from the date of manufacture. After opening, use within 6 months for optimal accuracy.
2. Is this sodium standard compatible with ICP-OES instruments?
While primarily formulated for ICP-MS applications, this 1000 ppm sodium standard can be used with ICP-OES systems. However, you may need to adjust dilution factors as ICP-OES typically requires higher concentration standards for optimal signal response.
3. What matrix components are present in this standard solution?
The solution contains ultra-pure sodium in a dilute nitric acid matrix (typically 2-5% v/v HNO₃) to ensure stability. The acid concentration is optimized to minimize polyatomic interferences while maintaining solubility.
4. Can this standard be used for preparing calibration curves?
Yes, this 1000 ppm sodium standard is specifically designed for preparing multi-point calibration curves. Its certified concentration allows for precise serial dilutions to create standards ranging from ppb to ppm levels as required by your analytical method.
5. What certification or traceability documentation is provided with this standard?
Each bottle includes a certificate of analysis detailing the exact concentration, uncertainty values, expiration date, and traceability information to NIST SRM or equivalent reference materials. The certificate also specifies the analytical methods used for verification.
