FAQs
1. How is this Selenium standard primarily used in laboratories?
This Selenium (Se) 1000 mg/L AAS standard is predominantly used for calibrating Atomic Absorption Spectrometry (AAS) instruments, validating analytical methods, and as a quality control standard for elemental analysis in various samples.
2. What does NIST traceable mean for the accuracy of my experiments?
NIST traceable means that the standard’s concentration has been measured against primary reference materials certified by the National Institute of Standards and Technology. This ensures the highest level of accuracy, reliability, and international comparability for your analytical results.
3. Why is this Selenium standard supplied in a Nitric Acid (HNO3) matrix?
The HNO3 matrix provides excellent stability for the Selenium ion, preventing precipitation or adsorption to container walls. It also offers good compatibility with most AAS and ICP instruments, minimizing matrix effects and ensuring accurate measurements.
4. How should I properly store this Selenium AAS standard to maintain its stability?
For optimal stability and to preserve its certified concentration, this standard should be stored tightly capped in its original container at room temperature, away from direct sunlight and extreme temperature fluctuations. Avoid contamination during use.
5. Can this 1000 mg/L standard be diluted for lower concentration applications?
Yes, this 1000 mg/L Selenium standard is designed to be diluted. Always use high-purity diluents (e.g., deionized water, diluted HNO3) and calibrated volumetric glassware to prepare working standards of lower concentrations accurately.
