Description

9-Methylbenzo[A]Pyrene Standard Solution is a high-purity, certified reference material (CRM) used for analytical calibration and quality control. This solution is critical for ensuring the accuracy and traceability of analytical methods in environmental and safety testing. It is an essential tool for analytical laboratories in the environmental monitoring, petrochemical, and occupational health sectors that require precise quantification of polycyclic aromatic hydrocarbon (PAH) derivatives.

Application

• Analytical Method Calibration: Primary standard for calibrating GC-MS, HPLC, and LC-MS instruments for the quantification of methylated PAHs.
• Environmental Analysis: Used in the testing of soil, water, and air samples for PAH contamination and source identification studies.
• Petrochemical & Fuel Testing: Essential for analyzing complex hydrocarbon mixtures, including crude oil, diesel, and lubricants, to assess composition and impurities.
• Occupational Health & Safety: Serves as a reference standard for monitoring workplace air and material safety in industries handling combustion products or coal tar derivatives.
• Food Safety Testing: Used in methods to detect and quantify PAH contaminants in smoked foods, grilled meats, and edible oils.
• Research & Development: A key reagent in toxicological studies, metabolic pathway research, and the development of new analytical protocols for complex organic compounds.
• Quality Assurance/Quality Control (QA/QC): Acts as a control standard to validate laboratory performance and ensure compliance with methods like EPA, ISO, and ASTM.
