Product Overview
This 1000 ppm Tellurium ICP-ML single-element standard delivers exceptional purity and stability for demanding trace elemental analysis. Formulated in a high-purity nitric acid matrix (2-5%), it eliminates matrix interference while ensuring long-term stability with minimal drift. The standard is rigorously tested for accuracy against NIST-traceable reference materials, providing ±1% concentration tolerance for reliable calibration curves. Packaged in HDPE bottles with tamper-evident seals, it prevents contamination from leachables or environmental exposure. The low-particulate formulation minimizes nebulizer clogging in ICP systems, while the optimized acidity ensures compatibility with most sample preparation protocols. Each batch undergoes multi-point quality control including ICP-OES verification to confirm homogeneity and absence of spectral interferences. The extended shelf life of 24 months under proper storage conditions reduces replacement frequency while maintaining performance consistency. Designed for laboratories requiring ultra-low detection limits, this standard enables precise quantification of tellurium in complex matrices like geological, environmental, or metallurgical samples where matrix effects commonly challenge accuracy.
FAQs
1. What is the exact matrix composition of this Tellurium standard?
The standard is prepared in 2-5% high-purity nitric acid with <0.1% HCl to stabilize tellurium in solution while maintaining compatibility with most ICP instruments. The ultra-low total dissolved solids content prevents matrix effects during analysis.
2. How does the packaging prevent contamination during storage?
The HDPE bottles feature a triple-layer barrier with an inner PTFE lining and tamper-evident seals. The leak-proof design maintains concentration integrity even during temperature fluctuations, while the amber tint blocks UV degradation of the standard.
3. Can this standard be used for tellurium speciation studies?
While optimized for total tellurium analysis, the standard’s purity profile (with <0.0005% organic carbon content) makes it suitable as a calibration reference for speciation workflows when combined with appropriate chromatographic separation techniques.
4. What is the recommended storage temperature range?
Store between 15-25°C in the original sealed container. Avoid refrigeration as temperature cycling can cause condensation that may alter the concentration. The standard remains stable for 24 months under these conditions.
5. How does this compare to multi-element standards containing tellurium?
This single-element standard eliminates potential inter-element interactions that can occur in multi-element solutions, particularly with tellurium’s tendency to form volatile hydrides. The dedicated formulation ensures 100% bioavailability of tellurium ions during nebulization.
