Product Overview
This Specpure® gold plasma standard solution delivers a certified concentration of 10,000µg/ml (1% w/v) in a stable hydrochloric acid matrix, engineered for unmatched accuracy in trace metal analysis. The ultra-high purity grade ensures minimal interference from contaminants, making it ideal for calibrating high-sensitivity instruments like ICP-OES, ICP-MS, and atomic absorption spectrometers (AAS). Each batch undergoes rigorous quality control to guarantee consistency, with full traceability to NIST or equivalent reference materials. The solution’s homogeneous composition eliminates precipitation risks, while the acid matrix enhances long-term stability—critical for repetitive lab workflows. Compatible with most plasma spectroscopy systems, this standard eliminates the need for in-house dilution errors, providing ready-to-use reliability for quantitative elemental analysis. The amber glass packaging protects against photodegradation, preserving integrity during storage and transport. Whether for routine calibration or research-grade precision, this gold standard solution meets the exacting demands of modern analytical laboratories, offering reproducibility that reduces recalibration frequency and operational costs.
FAQs
1. What is the shelf life of this gold plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C in its original packaging. Avoid exposure to direct sunlight or temperature fluctuations to prevent degradation of the matrix or concentration shifts. Once opened, use within 6 months for optimal accuracy, though stability may extend if handled under inert conditions.
2. Can this standard be used with organic solvents for sample preparation?
This aqueous solution is formulated for direct use in plasma-based techniques and is not designed for organic solvent compatibility. Introducing organic solvents may alter the solution’s viscosity or cause phase separation, compromising the gold concentration. For organic matrices, consider a gold standard dissolved in a compatible solvent or perform a validated extraction procedure before analysis.
3. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to remove trace metallic and anionic impurities that could interfere with ultra-low detection limits. Unlike general analytical grades, Specpure® provides certified purity levels (typically <10 ppb for most contaminants) and tighter concentration tolerances (±0.5%), backed by lot-specific certificates of analysis. This grade is essential for applications where background noise or matrix effects must be minimized, such as environmental or clinical trace metal testing.
4. What precautions should be taken when handling this hydrochloric acid-based solution?
Always wear nitrile gloves, safety goggles, and a lab coat when handling, as the hydrochloric acid matrix (typically 1–5% v/v) can cause skin and eye irritation. Work in a fume hood to avoid inhaling vapors, especially during pipetting or dilution. In case of spillage, neutralize with sodium bicarbonate solution before cleaning. Store the bottle upright with a secondary containment tray to prevent leaks, and ensure the cap is tightly sealed after each use to prevent acid evaporation.
5. Is this solution compatible with mercury or other heavy metal standards in multi-element calibration?
While this gold standard can be combined with other Specpure® single-element standards for multi-element calibration, avoid mixing with mercury standards due to potential redox reactions that may precipitate gold or alter concentrations. For multi-element workflows, prepare fresh dilutions daily using a common acid matrix (e.g., 2% HNO₃) and verify compatibility via spike recovery tests. Pre-mixed multi-element standards are recommended for routine use to ensure stability and accuracy.
