FAQs
1. What is the shelf life of this selenium standard solution?
The selenium standard solution has a shelf life of 24 months when stored unopened at room temperature in its original packaging. Once opened, it should be used within 6 months for optimal accuracy.
2. Is this solution compatible with ICP-OES or ICP-MS instruments?
While primarily designed for AAS, this selenium standard solution can be used with ICP-OES or ICP-MS instruments, provided the concentration is adjusted to match the instrument’s detection range.
3. Are there lower-concentration alternatives available for this selenium standard?
Lower-concentration selenium standards (e.g., 100 mg/L or 10 mg/L) are available and can be prepared by diluting this 1000 mg/L solution with an appropriate solvent, such as deionized water or dilute acid.
4. How should this solution be stored to maintain stability?
Store the solution in a tightly sealed container at room temperature (15–25°C), away from direct sunlight and moisture. Avoid freezing, as it may alter the solution’s homogeneity.
5. Does this solution require any special handling precautions?
Yes, selenium compounds can be toxic. Handle with gloves in a well-ventilated area, and avoid inhalation or skin contact. Dispose of waste according to local environmental regulations.
