Product Overview

This Specpure® mercury standard solution delivers 1000µg/ml Hg in a stabilized hydrochloric acid matrix, engineered for uncompromising accuracy in atomic absorption spectroscopy. The ultra-high purity formulation minimizes matrix interferences, ensuring reliable calibration curves and trace-level quantitation down to ppb concentrations. Each batch undergoes rigorous multi-point verification against NIST-traceable reference materials, with certified values provided for Hg content. The solution’s acid-stabilized composition prevents mercury precipitation or adsorption to container walls, maintaining homogeneity throughout the shelf life. Packaged in HDPE bottles with tamper-evident seals, it meets ISO 17034 and ISO Guide 31 requirements for reference materials. The low background impurity profile (<10 ppb for most common interferents) makes it particularly suitable for environmental, clinical, and industrial applications requiring ultra-low detection limits. Compatibility with most AAS and ICP instruments is verified, though users should confirm instrument-specific matrix requirements. For long-term storage, the solution remains stable for 24 months when unopened and stored at 15-25°C, protected from light exposure.

FAQs

1. What is the exact matrix composition of this mercury standard?

The solution contains mercury nitrate in 2-5% v/v hydrochloric acid, with proprietary stabilizers to prevent mercury loss through volatilization or adsorption. The exact acid concentration is optimized for compatibility with most AAS instruments while maintaining mercury solubility.

2. Can this standard be used for cold vapor AAS applications?

Yes, the solution is fully compatible with cold vapor generation techniques when properly diluted. The hydrochloric acid matrix actually enhances mercury vapor generation efficiency compared to nitric acid-based standards, though you may need to adjust your reduction conditions slightly.

3. What alternatives exist for lower concentration mercury standards?

For working standards below 1000µg/ml, we recommend serial dilution using 1% v/v nitric acid as the diluent. Pre-diluted standards at 100µg/ml and 10µg/ml concentrations are also available in our Specpure® line, prepared from the same parent solution to maintain traceability.

4. How should I handle potential mercury vapor exposure during use?

Always work in a properly ventilated fume hood when handling this solution. The concentrated form can release hazardous mercury vapor, particularly when heated or agitated. Use spill containment trays and wear nitrile gloves with arm protection, as mercury can permeate standard latex gloves.

5. What documentation comes with each bottle for quality assurance?

Every bottle includes a Certificate of Analysis detailing the certified mercury concentration, uncertainty values, expiration date, and batch-specific stability data. The CoA also lists tested interferents and their maximum concentrations, along with recommended storage conditions and handling precautions.
