Product Overview
This Lead AAS standard solution from Specpure® delivers unmatched purity and consistency for demanding analytical applications. Formulated at a precise concentration of 1000µg/ml, it serves as a reliable reference material for atomic absorption spectroscopy (AAS), ensuring accurate calibration and trace metal quantification. The Specpure® grade guarantees minimal matrix interference, with impurities controlled to sub-ppm levels, making it ideal for high-sensitivity analyses. Each batch undergoes rigorous quality control, including ICP-MS verification, to confirm traceability and stability. The solution is provided in high-density polyethylene (HDPE) bottles to prevent contamination, with tamper-evident seals for integrity assurance. Its long shelf life and ready-to-use formulation eliminate the need for dilution in most standard protocols, streamlining workflow efficiency. Whether used for environmental monitoring, industrial quality control, or research applications, this standard solution maintains performance consistency across diverse sample matrices. The 100ml and 500ml pack sizes offer flexibility for both low-volume testing and high-throughput laboratories, reducing waste while ensuring cost-effectiveness.
FAQs
1. What is the shelf life of this Lead AAS standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15-25°C). Always check the label for the exact expiration date.
2. Can this standard be used with graphite furnace AAS systems?
Yes, this 1000µg/ml Lead standard is compatible with both flame and graphite furnace AAS instruments, though you may need to dilute it further for graphite furnace applications depending on your detection limits.
3. How should I store the solution after opening?
After opening, tightly recap the bottle and store it in a cool, dry place away from direct sunlight. For extended stability, consider aliquoting into smaller amber glass vials if frequent access is required.
4. Is this solution certified or traceable to NIST standards?
The Specpure® grade follows ISO 17034 and ISO/IEC 17025 guidelines, with traceability to NIST SRMs (Standard Reference Materials) where applicable. The certificate of analysis provides detailed traceability information.
5. What alternatives are available if I need a lower concentration?
For lower concentrations, you can prepare dilutions using high-purity nitric acid (1% v/v) as the diluent. Alternatively, some suppliers offer pre-diluted standards at 100µg/ml or 10µg/ml concentrations.
