Product Overview
This Specpure® Terbium plasma standard solution delivers exceptional purity and accuracy for demanding elemental analysis applications. Formulated at a precise 1000µg/ml concentration in a stabilized nitric acid matrix, it ensures minimal background interference and superior signal stability in ICP-OES, ICP-MS, and AAS instruments. The solution undergoes rigorous quality control to meet international standards, with traceability to NIST SRMs for reliable quantification. Its low particulate content and consistent homogeneity eliminate calibration drift, reducing the need for frequent recalibration. The Specpure® grade guarantees ultra-low levels of contaminant metals, making it ideal for trace-level determinations in complex matrices. Packaged in HDPE bottles with tamper-evident seals, the solution maintains stability for extended shelf life under proper storage conditions. Each batch includes a comprehensive Certificate of Analysis detailing elemental impurities, density, and pH values for full transparency. Compatible with most autosampler systems, this standard solution integrates seamlessly into existing lab workflows without requiring additional preparation steps.
FAQs
1. What is the matrix composition of this Terbium standard solution?
The solution is prepared in a high-purity nitric acid matrix (typically 2-5% HNO₃) to ensure complete dissolution and long-term stability of the Terbium ions.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000µg/ml concentration is optimized for dilution across both techniques, though you may need to adjust final concentrations based on your instrument’s sensitivity requirements.
3. What is the typical shelf life of this plasma standard solution?
When stored unopened at 15-25°C in its original container, the solution remains stable for 24 months from the date of manufacture as indicated on the label.
4. Are the bottles provided with this standard solution autosampler-compatible?
The HDPE bottles feature a screw cap design that fits most standard autosampler racks, though you may need to transfer to vials for specific instrument requirements.
5. How does the Specpure® grade differ from standard analytical grades?
Specpure® standards undergo additional purification steps to achieve lower detection limits for contaminant elements, with certified impurity levels typically below 10 ppb for most metals.
