Overview:The department of inorganic chemistry is one of the six departments in the Central Laboratory for Environmental Quality Monitoring (CLEQM). The core areas of the laboratory are metal ions (minor, trace and heavy metals), anions, cations and physical parameters (pH, EC, alkalinity, odor, color, turbidity and dissolved oxygen). The research has links several application areas like soil, plant and ecotoxicology departments. Each laboratory houses a number of up-to-date and fully automated analytical instruments that are capable of handling a wide range of physico-chemical parameter in the field of water and digested samples analyses. Inorganic department includes four major analytical laboratories. The department is participating in the United Nation (UN) GEMS/ Water Performance Evaluation (PE) program. The laboratories has successfully obtained ISO/IEC 17025 from an internationally.
