Product Name – Tantalum, 1000 ppm ICP-ML, single-element standard
Quantity/Pack Size – 100 ml
Form – Liquid (Aqueous Solution)
Grade – ICP-ML (Inductively Coupled Plasma-Mass Spectrometry)
Application – Trace elemental analysis, calibration standards
Product Overview
The Tantalum 1000 ppm ICP-ML single-element standard is a high-purity calibration solution designed for precise trace metal analysis in inductively coupled plasma-mass spectrometry (ICP-MS) applications. This aqueous standard is manufactured under stringent quality controls to ensure consistent accuracy and reliability in analytical testing. The 1000 ppm concentration provides an optimal balance for calibration curves, reducing dilution errors while maintaining sensitivity for low-level detection. Formulated with ultra-pure reagents and stabilized in a matrix-compatible solution, this standard minimizes matrix interferences and ensures long-term stability when stored properly. The ICP-ML grade certification guarantees compliance with international analytical standards, making it suitable for research laboratories requiring reproducible results. Packaged in a 100 ml HDPE bottle with tamper-evident sealing, the solution is protected from contamination and evaporation. Each batch undergoes rigorous multi-point quality testing, including spectral interference checks and concentration verification, to meet the demands of high-throughput laboratories. The solution’s homogeneity and stability are validated for at least 24 months when stored under recommended conditions.
FAQs
1. What is the matrix composition of this Tantalum standard?
This standard is prepared in a dilute nitric acid matrix (typically 2-5% v/v) to ensure complete dissolution and stability of the Tantalum ions while maintaining compatibility with ICP-MS instrumentation. The exact matrix composition is optimized to minimize polyatomic interferences that could affect Tantalum detection at 181 m/z.
2. Can this standard be used for ICP-OES applications?
While primarily formulated for ICP-MS, this 1000 ppm Tantalum standard can be used for ICP-OES applications with appropriate dilution. However, the higher concentration may require significant dilution to fall within the optimal working range of most ICP-OES instruments, typically in the low ppm to ppb range for Tantalum analysis.
3. What are the recommended storage conditions?
Store the unopened bottle at room temperature (15-25°C) in its original packaging, away from direct sunlight and heat sources. After opening, keep the bottle tightly sealed and store upright to prevent leakage. For long-term storage of opened bottles, consider transferring aliquots to smaller, airtight containers to minimize exposure to atmospheric contaminants.
4. How does the shelf life change after opening?
The certified 24-month shelf life applies to unopened bottles when stored properly. Once opened, the standard remains stable for at least 12 months if stored under recommended conditions and protected from contamination. Regular verification of concentration is advised for opened bottles used beyond 6 months, particularly in high-humidity environments.
5. What certification documentation is provided with this standard?
Each bottle is accompanied by a comprehensive Certificate of Analysis that includes the measured concentration with uncertainty values, lot-specific expiration date, storage instructions, and traceability information. The certificate also details the preparation method, matrix composition, and quality control test results, including spectral interference checks at relevant m/z values.
