Under the supervision of the Dean of the College of Pharmacy, Associate Professor Dr. Sarmed H. Kathum Alkhateeb, and for the students of the fifth stage to benefit from practical graduation projects, A fifth-stage student visited the Ministry of Science and Technology/Department of Environment and Water/Environmental Research Center to learn how to identify the volatile oils extracted from the Iraqi Cupressus sempervirens plant. Supervised by Assistant Teacher Mais Abd Alreza, a faculty member at the Pharmacognosy and Medicinal Plants Department . The volatile oils were investigated using a gas chromatography/mass spectrometer device. It consists of two different parts of qualitative analysis. The first part, gas chromatography, is an analytical technique used to separate the chemical components of the sample mixture and then determine their presence or absence. It uses carrier gas in separation operations. The carrier gas perfectly transports the sample molecules without interacting with the sample or damaging the device components. The second part, mass spectrometry, is an analytical technique added to gas chromatography and used instead of a gas chromatography detector. Neutral molecules are separated from the analytical column and ionized at the ion source to produce molecular ions. The fragment and molecular ions are then separated and detected on the mass analyzer based on their mass/charge ratio.
