Product Overview
This Tungsten 10 ppm ICP-ML single-element standard delivers exceptional purity and consistency for demanding inductively coupled plasma mass spectrometry (ICP-MS) applications. Formulated in a high-purity acid matrix, this standard eliminates interference risks while providing stable tungsten concentrations for accurate instrument calibration. The 10 ppm concentration offers optimal sensitivity for trace-level tungsten analysis in environmental samples, metallurgical studies, and material characterization. Each batch undergoes rigorous multi-point verification against NIST-traceable reference materials to ensure ±1% concentration accuracy. The solution’s extended shelf life (24 months when stored properly) and low particulate content (<0.2 µm filtered) make it ideal for routine lab operations. Packaged in HDPE bottles with tamper-evident seals, this standard maintains integrity during transport and storage. The ICP-ML grade certification guarantees compatibility with modern ICP-MS systems, including those with collision/reaction cell technologies. For laboratories requiring tungsten analysis at ppb levels, this standard provides the precision foundation needed for reliable quantitative results across diverse sample matrices.
FAQs
1. What is the matrix composition of this tungsten standard?
This standard is prepared in a 2% nitric acid matrix using ultra-pure reagents to minimize background interference while maintaining tungsten stability.
2. Can this standard be used for tungsten isotope ratio measurements?
Yes, the high purity and certified isotopic composition make it suitable for isotope ratio analysis when proper mass bias correction procedures are applied.
3. What’s the recommended storage temperature for long-term stability?
Store between 15-25°C in the original container, away from direct sunlight and strong magnetic fields to maintain certified concentration values.
4. Does this standard contain any preservatives or stabilizers?
The solution contains no additional preservatives – stability is maintained through the acid matrix and proper storage conditions.
5. What’s the typical detection limit when using this standard?
With modern ICP-MS instrumentation, this 10 ppm standard enables reliable quantification down to low ppt levels when properly diluted.
