Product Overview
This Specpure® silicon plasma standard solution delivers 1000µg/ml silicon in a 1% nitric acid matrix, engineered for unmatched accuracy in spectroscopic analysis. The ultra-high-purity grade (99.999% minimum) eliminates matrix interferences, ensuring reliable calibration curves for ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS) systems. Each batch undergoes rigorous multi-element impurity testing (≤10 ppb for most contaminants) and is NIST-traceable for compliance with ISO 17025 standards. The solution’s acid-stabilized formulation resists precipitation and microbial growth, guaranteeing a 24-month shelf life when stored at 15–25°C. Packaged in HDPE bottles with tamper-evident seals, it minimizes leachables while the amber tint protects against photodegradation. Compatible with most autosamplers, the low-viscosity matrix reduces carryover in automated systems. Ideal for semiconductor doping analysis, environmental silica monitoring, or alloy composition verification, this standard eliminates the need for in-house dilution in routine lab workflows.
FAQs
1. Can this silicon standard be used directly for ICP-MS without further dilution?
While the 1000µg/ml concentration is suitable for ICP-OES, ICP-MS typically requires dilution to 1–100 ppb ranges to avoid detector saturation. Always validate with your instrument’s linear range.
2. What’s the difference between Specpure® and regular analytical-grade silicon standards?
Specpure® undergoes additional purification steps to reduce metallic impurities below 10 ppb (vs. 100+ ppb in standard grades), critical for ultra-trace analysis in semiconductor or high-purity material testing.
3. Is this solution compatible with organic solvents like methanol or acetone?
The nitric acid matrix may react with organic solvents. For organic-compatible standards, consider our silicon standards in hydrochloric acid or request a custom solvent blend.
4. How should I handle the bottle to prevent contamination?
Use powder-free nitrile gloves and work under a laminar flow hood. Avoid touching the bottle neck or cap interior. For sub-sampling, use dedicated Class A volumetric pipettes.
5. What’s the typical lead time for the 500ml pack size?
Stock items ship within 2–3 business days. The 500ml size may require 5–7 days for batch certification; check real-time availability in the cart.
