Product Overview
This Zinc 1000 ppm ICP-ML single-element standard is meticulously formulated to deliver exceptional precision in inductively coupled plasma-mass spectrometry (ICP-MS) applications. The solution is prepared using ultra-high-purity zinc in a stabilized nitric acid matrix, ensuring long-term stability and minimal interference during analysis. Each batch undergoes rigorous quality control to guarantee concentration accuracy within ±1% tolerance, with full NIST traceability for compliance with international standards. The low-particle formulation minimizes instrument contamination, while the acidified base prevents precipitation or microbial growth, extending shelf life without compromising performance. The standard is packaged in high-density polyethylene (HDPE) bottles with tamper-evident seals, designed to prevent leaching or external contamination. Its compatibility with most ICP-MS and ICP-OES systems makes it versatile for diverse analytical workflows, from environmental monitoring to industrial process control. The 1000 ppm concentration offers optimal sensitivity for both high- and low-range dilutions, reducing preparation time while maintaining linear response across calibration curves. Whether used for routine lab testing or research-grade analysis, this standard eliminates variability associated with in-house preparations, ensuring reproducible results batch after batch. The solution’s clarity and homogeneity are verified through advanced spectroscopic techniques, with certificates of analysis provided for each lot.
FAQs
1. What is the shelf life of this Zinc 1000 ppm ICP standard when stored properly?
The standard remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original container, protected from direct sunlight and moisture. Once opened, use within 6 months for optimal accuracy, though recertification via internal standards is recommended for extended storage periods.
2. Can this standard be used directly for ICP-OES (Optical Emission Spectrometry) applications?
Yes, this 1000 ppm Zinc standard is fully compatible with ICP-OES systems, though you may need to adjust dilution factors based on your instrument’s detection limits and the expected concentration range of your samples. The nitric acid matrix (typically 2–5%) is suitable for most ICP-OES methodologies without requiring additional digestion steps.
3. What materials are used for the bottle and cap to prevent contamination?
The solution is packaged in high-density polyethylene (HDPE) bottles with polypropylene (PP) caps, both of which are pre-cleaned using Class 100 cleanroom protocols. The materials are tested for trace metal leaching and comply with ASTM E1727 standards for ultra-low background contamination, ensuring no interference with zinc measurements.
4. Is this standard suitable for preparing multi-element calibration curves?
While this is a single-element standard, it can be combined with other eqipped ICP standards (e.g., copper, lead, cadmium) to create custom multi-element calibration solutions. Ensure all standards share a compatible acid matrix (preferably nitric acid-based) and verify compatibility via a blank test before mixing to avoid precipitation or spectral overlaps.
5. How does the acid concentration in this standard affect sample preparation?
The standard contains ~2% v/v nitric acid, which acts as a stabilizer and matches the acidity of most digested environmental or biological samples. For samples with higher organic content, you may need to adjust the final acid concentration to 5–10% to maintain solubility and prevent matrix effects during analysis. Always perform matrix matching when possible for highest accuracy.
