Product Overview
The Lanthanum 10 ppm ICP-ML single-element standard is a high-purity, matrix-matched solution engineered for precise calibration in inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES). Formulated in a stabilized aqueous matrix, this standard ensures minimal interference and maximum signal stability during elemental analysis. The 10 ppm concentration is optimized for mid-range calibration curves, providing linear response across typical analytical ranges while maintaining compatibility with most ICP instrumentation. Each batch undergoes rigorous multi-point verification against NIST-traceable reference materials to guarantee accuracy within ±1% relative standard deviation. The solution is packaged in HDPE bottles with tamper-evident seals to prevent contamination and evaporation. Its low acidity (≤2% HNO₃) preserves instrument longevity while maintaining element solubility. The standard’s extended shelf life of 24 months under proper storage conditions (15-25°C) reduces frequency of recalibration, enhancing laboratory efficiency. The accompanying Certificate of Analysis documents traceability, expiry, and lot-specific data for GLP/GMP compliance. This standard is particularly valuable for laboratories requiring consistent performance in rare earth element analysis, where matrix effects and spectral interferences are common challenges.
FAQs
1. What is the matrix composition of this Lanthanum standard?
The standard is prepared in a dilute nitric acid matrix (≤2% HNO₃) with 18.2 MΩ·cm ultrapure water, optimized to minimize polyatomic interferences while maintaining element stability. The matrix matches typical ICP sample preparation protocols for seamless integration into existing workflows.
2. Can this standard be used for ICP-OES as well as ICP-MS?
Yes, the 10 ppm concentration is suitable for both ICP-MS and ICP-OES applications. For ICP-OES, you may need to dilute further depending on your instrument’s linear range for lanthanum’s primary emission lines (379.478 nm, 392.702 nm, 407.735 nm). Always verify against your method’s calibration requirements.
3. What alternatives exist for higher concentration Lanthanum standards?
For higher concentrations, consider our 100 ppm or 1,000 ppm Lanthanum ICP standards, which allow for serial dilution to create multi-point calibration curves. These higher-concentration standards are ideal for laboratories analyzing samples with elevated lanthanum content or requiring wider dynamic ranges.
4. How should this standard be stored to maintain stability?
Store the unopened bottle at 15-25°C in its original packaging, away from direct sunlight and sources of heat or ignition. Once opened, tightly recap after each use and store upright to prevent leakage. Avoid freezing, as this may alter the solution’s homogeneity. Under these conditions, the standard remains stable for 24 months from the date of manufacture.
5. Is this standard compatible with automated liquid handling systems?
The solution’s viscosity and surface tension are optimized for compatibility with most automated pipetting systems and liquid handlers. For best results, use low-retention pipette tips and pre-rinse them with the standard before dispensing to minimize carryover. The HDPE bottle’s design also accommodates standard laboratory bottle-top dispensers.
