Product Overview
The 1000 ppm silver ICP-ML single-element standard is a high-purity reference solution designed for inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS) applications. Prepared in a 2% nitric acid matrix, this standard ensures minimal interference and maximum stability during analysis. Each batch undergoes rigorous quality control to guarantee accuracy within ±1% of the stated concentration, with traceability to NIST-certified reference materials. The solution is filtered through 0.22 µm membranes to eliminate particulate contamination, making it suitable for sensitive instrumentation. Housed in HDPE bottles with tamper-evident seals, the standard maintains integrity during storage and transport. The low matrix interference and extended shelf life (12+ months when stored properly) reduce the need for frequent recalibration, improving lab efficiency. Compatible with most ICP-OES, ICP-MS, and AAS systems, this standard delivers consistent performance across diverse analytical workflows. The nitric acid base ensures complete metal solubility while preventing precipitation or adsorption losses.
FAQs
1. What is the shelf life of this silver standard when unopened?
The unopened 1000 ppm silver standard remains stable for at least 12 months from the date of manufacture when stored at 15-25°C in its original packaging.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000 ppm concentration is suitable for both ICP-OES and ICP-MS, though you may need to dilute it further for ICP-MS to avoid detector saturation.
3. What material are the bottles made from, and are they leak-proof?
The bottles are made from high-density polyethylene (HDPE) with tamper-evident, screw-cap seals that prevent leakage during storage and shipping.
4. Is this standard compatible with mercury analysis in the same run?
While the nitric acid matrix is compatible with most metals, mercury requires special handling due to its volatility; sequential analysis is recommended.
5. How should I dispose of unused silver standard solution?
Follow local hazardous waste regulations for disposal; the nitric acid matrix and silver content typically classify this as chemical waste requiring professional handling.
