Product Overview
The Specpure® Semi Metals Plasma Standard Solution is a high-precision calibration standard designed for trace metal analysis in advanced spectroscopic techniques. This solution contains 11 semi-metals—Arsenic (As), Bismuth (Bi), Gallium (Ga), Germanium (Ge), Indium (In), Lead (Pb), Antimony (Sb), Selenium (Se), Tin (Sn), Tellurium (Te), and Thallium (Tl)—each at a concentration of 100µg/ml, ensuring consistent and accurate measurements. The Specpure® grade guarantees ultra-high purity, minimizing matrix interferences and background noise for superior analytical performance. Formulated in an aqueous matrix, this standard is optimized for compatibility with Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and Atomic Absorption Spectroscopy (AAS). Its stability and homogeneity make it ideal for routine calibration, method validation, and quality control in laboratories requiring precise quantification of semi-metals. The solution is supplied in amber glass bottles to protect against light-induced degradation, ensuring long-term stability and reliability in critical applications.
FAQs
1
What is the shelf life of this plasma standard solution when stored properly?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature in its original packaging, protected from light and moisture. 2
Is this standard compatible with organic solvent-based sample preparation methods?
This aqueous-based standard is primarily designed for water-compatible systems. For organic solvent applications, dilution or matrix-matching may be required to prevent phase separation or precipitation. 3
Can this solution be used for environmental water analysis without further dilution?
The 100µg/ml concentration is typically used for stock preparation. For environmental samples, serial dilution is recommended to match the expected analyte range and avoid instrument saturation. 4
What is the recommended storage temperature for long-term stability?
Store the unopened solution at 15–25°C in a dark, dry place. Avoid refrigeration unless specified for extended storage beyond the labeled shelf life. 5
Are there lower-concentration alternatives available for trace-level detection?
Lower-concentration standards (e.g., 10µg/ml or 1µg/ml) are often derived from this stock by dilution. For pre-diluted options, check compatibility with your specific analytical requirements.
