Lead Standard Solution (1000 mg/L or ppm) is a highly precise, certified liquid used for calibrating analytical instruments (AAS, ICP-OES, ICP-MS) to detect trace amounts of lead, containing 1 gram of lead (Pb) per liter, typically dissolved from high-purity lead salts (like lead nitrate) in a dilute nitric acid (HNO₃) matrix for stability, acting as a reference material for accurate lead analysis in environmental or quality control labs.Concentration: Exactly 1000 mg/L (milligrams per liter) or 1000 ppm (parts per million) of lead (Pb).
Matrix: A dilute acid (usually nitric acid, HNO₃) to keep the lead ions (Pb²⁺) stable and prevent precipitation.
