Product Overview
This Manganese single-element standard is formulated at a precise 1000 ppm concentration in a stabilized nitric acid matrix, ensuring long-term stability and minimal matrix interference. The solution is manufactured under ISO 17034 and ISO/IEC 17025 guidelines, with full NIST-traceable certification to guarantee accuracy for instrumental calibration. The ultra-low impurity profile (<10 ppb for most contaminants) makes it suitable for high-sensitivity applications where background interference must be minimized. Packaged in HDPE bottles with tamper-evident seals, the standard resists leaching and contamination during storage. The 2-5% HNO₃ matrix prevents precipitation while maintaining compatibility with most ICP sample introduction systems. Each batch undergoes rigorous homogeneity testing and is supplied with a comprehensive Certificate of Analysis detailing uncertainty values, expiry date, and storage conditions. The solution’s shelf life extends to 24 months when stored unopened at 15-25°C, with no detectable degradation in concentration over time.
FAQs
1. What is the exact acid concentration in this Manganese standard?
The standard is prepared in a 2-5% nitric acid (HNO₃) matrix, which serves as both a stabilizer and a solvent for the manganese content. This concentration range is optimized to prevent precipitation while remaining compatible with most ICP instrumentation without requiring additional dilution for routine analysis.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000 ppm concentration and ultra-pure formulation make it suitable for both ICP-OES and ICP-MS. For ICP-MS, you may need to perform serial dilutions to reach the lower ppb working ranges typical for that technique, but the standard’s low impurity profile ensures minimal spectral interferences even at high sensitivity settings.
3. How does the packaging prevent contamination during storage?
The standard is supplied in HDPE (High-Density Polyethylene) bottles that are chemically inert to the nitric acid matrix. The bottles feature tamper-evident seals and are cleaned using a Class 100 cleanroom protocol to remove trace metal contaminants. The cap liners are made of PTFE-faced material to resist acid corrosion and prevent leaching of metals into the solution.
4. What alternatives exist if I need a different concentration of Manganese standard?
For lower concentrations, you can prepare working standards by diluting this 1000 ppm solution with 2% HNO₃ (matching the matrix). For higher concentrations, multi-element standards containing manganese at 10,000 ppm are available, though these may introduce additional elements that require compensation during analysis. Always verify compatibility with your specific application requirements.
5. Does this standard require any special disposal procedures?
As a nitric acid-based solution containing manganese, it should be disposed of according to local hazardous waste regulations for heavy metal-containing liquids. Neutralization with a base (e.g., NaOH or NaHCO₃) followed by precipitation of manganese as Mn(OH)₂ is a common pretreatment method before disposal, but always consult your institution’s environmental health and safety guidelines for specific protocols.
