Instrumental Analysis

A specialized laboratory to conduct analysis related to environmental contaminants for all the environment elements, including soil, water, air, and following international quality standards with an emphasis on the regulation standard ISO / IEC 17025: 2005. It offers laboratory services to researchers and university students in the undergraduate and higher studies as well as supporting governmental institutions and companies of private sector interested in environmental affairs studies. Our goal is to achieve best accuracy and workmanship to reach excellence in community service and strive through our specialist society, the state and humanity in environmental aspects.

The laboratory obtained the reliability according to the Standard ISO⁄IEC 2005:17025 from the Laboratory Accreditation Department in the Central Agency for Standardization and Quality Control, the Iraqi Ministry of Planning in the testing of heavy metals and the measurement of dissolved salts.

Laboratory Staff:

1-  Prof. Dr. Abdul Hameed M. J. Al-Obeidi.

2- Senior Chief Eng. Athmar A. M. Jaafar

3- Senior Eng. Ali Nasser Ali

The laboratory is equipped with the following sophisticated instruments:

  1. Atomic Absorption Spectrophotometer 6300, Shimadzu, Japan.
  2. Flame Photometer, PFP7, Jenway, UK.
  3. Auto Analyzer, AA3, SEAL Analytical, Germany.
  4. UV1800-Spectrophotometer, Shimadzu, Japan.
  5. pH meter and electrical conductometer.

As well as the needed supporting equipments and devices such as:  distillation apparatus, fumes hood, microbalances, oven, furnace, vibrators, and water bath. The vast requirements of the Iraqi environment neceistate a lot of work ongoing analysis of its components to make sure no contamination and propose appropriate solutions for the treatment and disposal of contaminants, if any .... seeks Environmental Research Center and through laboratory automatic analysis to provide all the facilities available for those interested in the field in addition to providing educational lectures and education in the field of chemical analysis to environmental pollutants.

Many graduate and postgraduate students get the benefits from the experience and the facility of ERC. In 2014, five research projects for the analysis of heavy elements in favor of the employees of the center and postgraduate students from the College of Science for Girls, Baghdad University and the Institute of Laser, and the Department of Building and Construction at the University of Technology. In 2015, heavy metals analysis were as well as conducting various tests using UV-visible spectrometer (Shimadzu UV-1800) for the benefit of employees of the center and postgraduate students in the Building and Construction, and the Applied Science Departments at the University of Technology, as well as the completion of four research projects at ERC.
