Name: Boron standard solution (as elemental B).
-
Intended use: Calibration standard for ICP-OES / ICP-MS / colorimetry, QC, method validation.
-
Matrix: Deionized water (optionally 0.1–1% nitric acid for ICP stability if desired).
-
Typical concentration options: 0.1 mg·L⁻¹ to 1000 mg·L⁻¹ (1000 mg·L⁻¹ = 1000 ppm) prepared by dilution of a primary 1000 mg·L⁻¹ standard.
-
Appearance: Clear, colorless solution.
-
Storage: Amber glass or HDPE bottles, tightly capped; store at 15–25 °C, avoid direct sunlight.
-
Shelf life (typical): 6–12 months if prepared and stored cleanly; verify periodically.
