Product Overview
This Specpure® arsenic AAS standard solution delivers 1000µg/ml concentration in a stabilized, acidified matrix, ensuring exceptional accuracy for trace metal analysis. Manufactured under stringent quality controls, it meets the highest purity standards for atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) applications. The solution is prepared from ultra-high-purity arsenic metal dissolved in high-grade acids, minimizing matrix interferences and background noise. Each batch undergoes rigorous testing for homogeneity, stability, and contaminant levels, with full traceability to NIST or equivalent reference materials. The acidified formulation prevents precipitation and microbial growth, guaranteeing long-term stability even in tropical Indian lab conditions. Packaged in HDPE bottles with tamper-evident seals, it eliminates cross-contamination risks during storage or handling. Whether used for calibration curves, quality control checks, or routine analysis, this standard ensures reproducible results across instruments and operators. The 100ml and 500ml pack sizes offer flexibility for both high-throughput labs and occasional users, reducing waste while maintaining cost efficiency.
FAQs
1. What is the shelf life of this arsenic AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15-25°C. Once opened, use within 12 months for optimal accuracy.
2. Is this standard compatible with both flame and graphite furnace AAS?
Yes, the 1000µg/ml concentration is suitable for both techniques. For graphite furnace applications, further dilution may be required depending on your instrument’s sensitivity.
3. What acid matrix is used in this standard solution?
The solution is stabilized in a nitric acid matrix (typically 2-5% v/v), which ensures complete arsenic solubility and prevents adsorption losses.
4. Can this be used as a primary standard for calibration?
While it’s a high-purity secondary standard, it can serve as a primary standard if your lab validates its traceability to certified reference materials through proper documentation.
5. How should I dispose of unused arsenic standard solution?
Follow your institution’s hazardous waste protocols for arsenic-containing solutions. Neutralize with appropriate reagents before disposal as per Indian environmental regulations.
