Product Overview
This Calcium 10 ppm ICP-ML single-element standard delivers exceptional purity and stability for demanding trace metal analysis applications. Formulated in a 2% nitric acid matrix, it eliminates spectral interferences while maintaining long-term homogeneity. The standard is manufactured under ISO 17034 and ISO/IEC 17025 accredited processes, ensuring NIST-traceable accuracy with ±2% relative uncertainty. Each batch undergoes rigorous multi-point calibration verification using reference materials, with stability guaranteed for 24 months when stored properly. The ultra-low particulate formulation prevents nebulizer clogging in ICP systems, while the acidified matrix preserves elemental integrity during extended storage. Compatible with all major ICP-MS and ICP-OES instruments, this standard provides consistent response factors across different plasma conditions. The amber HDPE bottle with tamper-evident seal prevents contamination while allowing easy dispensing. Ideal for laboratories requiring high-precision calcium determinations in environmental, geological, or biological matrices.
FAQs
1. What is the matrix composition of this Calcium standard?
This standard uses a 2% ultra-pure nitric acid matrix that maintains elemental stability while minimizing spectral interferences during ICP analysis. The acid concentration is optimized for compatibility with most ICP sample introduction systems.
2. Can this standard be used for both ICP-MS and ICP-OES applications?
Yes, the 10 ppm concentration is suitable for both ICP-MS and ICP-OES instruments. For ICP-MS, it provides optimal signal intensity in the mid-range of the calibration curve, while for ICP-OES it offers sufficient sensitivity for most analytical requirements.
3. What is the shelf life and recommended storage conditions?
The standard maintains its certified concentration for 24 months from the date of manufacture when stored unopened at 15-25°C. After opening, it should be tightly sealed and stored under the same conditions, with recertification recommended after 12 months.
4. How does this compare to multi-element calcium standards?
Single-element standards like this provide higher accuracy for calcium-specific determinations by eliminating potential inter-element interactions that can occur in multi-element solutions. They’re particularly valuable when analyzing complex matrices where spectral overlaps might be problematic.
5. What quality control measures are implemented during production?
Each batch undergoes multi-point calibration using NIST-traceable reference materials, with verification at 5 concentration levels. The production process includes 3-stage filtration (0.2 μm final) and homogeneity testing across 10 sample points per batch to ensure consistency.
