Product Overview
This Barium 1000 ppm ICP-ML single-element standard is a high-purity liquid solution designed for precise inductively coupled plasma (ICP) spectroscopy applications. Formulated with ultra-low trace impurities, it ensures accurate calibration and reliable quantification in ICP-OES (Optical Emission Spectrometry) and ICP-MS (Mass Spectrometry) systems. The standard is stabilized in a nitric acid matrix to prevent precipitation and maintain long-term stability, making it suitable for demanding analytical workflows. Each batch undergoes rigorous quality control to guarantee consistency, with certified concentration values traceable to NIST standards. The solution is provided in a high-density polyethylene (HDPE) bottle with a tamper-evident seal to prevent contamination during storage and handling. Its ready-to-use formulation eliminates the need for dilution in most applications, reducing preparation time and minimizing human error. The low background interference ensures clean spectra, while the extended shelf life under proper storage conditions makes it a cost-effective choice for laboratories requiring frequent calibration.
FAQs
1. What is the shelf life of this Barium ICP standard?
When stored unopened at room temperature in its original container, this standard remains stable for 24 months from the date of manufacture. Exposure to direct sunlight or temperature fluctuations may reduce stability.
2. Is this standard compatible with both ICP-OES and ICP-MS instruments?
Yes, the 1000 ppm concentration is optimized for both ICP-OES and ICP-MS applications. For ICP-MS, further dilution may be required depending on your instrument’s sensitivity and the expected sample concentration range.
3. What alternatives are available if I need a different concentration?
Lower concentrations such as 100 ppm or 10 ppm can be prepared by serial dilution of this standard using high-purity nitric acid. Pre-diluted standards are also available separately for convenience.
4. How should I store this standard to maintain accuracy?
Store the unopened bottle upright at 15-25°C in a clean, dry environment away from direct sunlight and corrosive fumes. Once opened, recap tightly after each use and avoid prolonged exposure to air.
5. Does this standard contain any preservatives or stabilizers?
The solution contains trace amounts of high-purity nitric acid as a stabilizer to prevent hydrolysis and microbial growth. No additional preservatives are added to maintain spectral purity.
