Palladium standard solution. Description: Palladium standard solution is a high-purity, traceable reference material used for instrument calibration and quantitative analysis of palladium (Pd) in various matrices. It is commonly utilized in ICP-OES, ICP-MS, AAS, and other elemental analysis methods. Key Features: Composition: Palladium (Pd) dissolved in a nitric acid matrix Concentration: Commonly available at 1000 mg/L (ppm) Pd in HNO₃ (2–10% v/v) Purity: Prepared from ultra-pure palladium metal or salt (e.g., Pd(NO₃)₂) Matrix: Typically 2–10% HNO₃ (trace metal grade) Packaging: Sealed HDPE or glass bottles, often in 100 mL to 500 mL sizes Certifications: Supplied with Certificate of Analysis (CoA) and traceability to NIST standards Shelf Life: Long shelf life when stored properly (cool, dark conditions)
