Product Overview
This Specpure® Antimony plasma standard solution delivers exceptional purity and stability for demanding trace metal analysis applications. Formulated at a 10,000µg/ml concentration in a low-acidity nitric acid matrix (1-5%), it minimizes matrix interference while ensuring long-term stability. The Specpure® grade guarantees ultra-high purity (99.999% trace metals basis) with rigorous quality control, including NIST-traceable certification for analytical reliability. The solution is packaged in HDPE bottles with tamper-evident seals to prevent contamination and evaporation. Its homogeneous composition eliminates the need for pre-dilution shaking, while the amber tint protects against photodegradation. Compatible with most autosamplers and nebulizers, this standard maintains consistency across ICP-OES, ICP-MS, and AAS platforms. The extended shelf life (24 months unopened) and lot-specific certificates of analysis make it ideal for laboratories requiring reproducible results in environmental monitoring, toxicology studies, or industrial quality control. Each batch undergoes multi-element scanning to confirm the absence of interfering contaminants, with detection limits below 10ppt for most common interferents.
FAQs
1. What is the exact nitric acid concentration in this Antimony standard solution?
The matrix contains 1-5% ultra-pure nitric acid, optimized to balance solubility and instrument compatibility without introducing background interference.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
While the 10,000µg/ml concentration is suitable for some ICP-MS applications, most protocols require dilution to 1-100µg/ml working ranges to prevent detector saturation and matrix effects.
3. How does the Specpure® grade differ from standard ACS-grade antimony solutions?
Specpure® undergoes additional purification steps including sub-boiling distillation and ion exchange to remove trace impurities (e.g., As, Pb, Bi) that ACS-grade solutions may contain at ppm levels.
4. What storage conditions are required to maintain the 24-month shelf life?
Store unopened bottles at 15-25°C in the original packaging, away from direct sunlight and strong oxidizing agents. Opened bottles should be resealed with parafilm and consumed within 6 months.
5. Are the HDPE bottles compatible with organic solvent mixtures?
The bottles are tested for compatibility with aqueous solutions and dilute acids. For organic solvents (e.g., methanol, acetone), transfer to glass containers as HDPE may leach additives over time.
