Product Name – Arsenic, 10 ppm ICP-ML, single-element standard Quantity/Pack Size – 100 ml Form – Liquid Grade – ICP-ML Application – ICP-MS/OES calibration, trace elemental analysis
Product Overview
This Arsenic 10 ppm ICP-ML single-element standard is a high-purity liquid solution designed for precise calibration in inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectroscopy (ICP-OES). Formulated with ultra-low background impurities, it ensures accurate quantification of arsenic in environmental, food, or industrial samples. The 10 ppm concentration provides optimal sensitivity while maintaining linearity across analytical ranges. Each batch undergoes rigorous quality control, including multi-point verification against NIST-traceable reference materials, to guarantee consistency and reliability. The solution is stabilized in a nitric acid matrix (2% v/v) to prevent precipitation and extend shelf life. Packaged in HDPE bottles with tamper-evident seals, it minimizes contamination risks during storage or handling. Compatible with most ICP instruments, this standard eliminates matrix interferences, reducing the need for complex sample preparation. Its single-element formulation simplifies method development for arsenic-specific testing protocols.
FAQs
1. What is the shelf life of this Arsenic 10 ppm standard when unopened?
When stored at 15–25°C in its original sealed container, the standard remains stable for 24 months from the date of manufacture. Avoid exposure to direct sunlight or temperature fluctuations.
2. Can this standard be used for both ICP-MS and ICP-OES applications?
Yes, the 10 ppm concentration is optimized for compatibility with both ICP-MS and ICP-OES instruments, though dilution may be required for ICP-OES depending on your detection limits and linear range.
3. Is this standard traceable to NIST or other international reference materials?
The arsenic concentration is verified against NIST SRM 3103a (Arsenic Standard Solution) and certified with a traceability statement included in the Certificate of Analysis.
4. What precautions should be taken during handling to avoid contamination?
Use dedicated polypropylene or PFA pipette tips and containers to prevent cross-contamination. Always wear nitrile gloves and work in a laminar flow hood if handling in ultra-trace environments.
5. Does this standard contain any preservatives or stabilizing agents?
The solution is stabilized with 2% v/v high-purity nitric acid to maintain homogeneity and prevent microbial growth. No additional preservatives are added.
