Basic Knowledge on Chemistry Division

         The Chemistry Divison of the PNP Crime Laboratory was established in 1960 under the name Physical Science Division with the mission to respond to the need for Scientific Examination through the application of chemistry theories and principles in the examination of physical evidences. In February 2000, the Physical Science Division was split into Chemistry Division and Physical Identification Division.   The Chemistry Division examines substances using analytical technique while the Physical Identification Division handles trajectory and trace evidences.

Functions of Chemistry Division

1.    Conducts qualitative and quatitative examination for dangerous drugs, essential chemicals and controlled precursors under RA 9165 .
2.    Conducts examination of explosive and explosive ingredients.
3.    Conducts examination of gunshot residue.
4.    Conducts toxicological(chemical) examination of poisons in body fluids and food.
5.    Conducts blood alcohol determination.
6.    Conducts examination of fake products for unfair trade competition.
7.     (The Chemistry Division personnel)testifies and gives expert opinion where his expertise is required.
8.     Conducts field lab work and clandestine lab operation.
9.    Performs other duties assigned by the Director, Crime Laboratory and other superiors.

Sophisticated Instruments

1.    Scanning Electron Microscope(SEM) - Used for the physical examination of variuos forensic specimens such as hair, fibers, paint particles, drugs, metals, and other compounds. It is a software-controlled digital scanning elctron microscope used to produce striking images over a wide range of magnification (3X300,000X) on rough or covered surface of minute specimen.

2.    Gas Chromatography (GC) - An instrumental chromatography which utilizes the retention time for the detection of drugs, toxic compounds, explosives, volatile, and semi-volatile compounds. Qualitative and quantitative analysis can be achieved in one detection.

3.    Gas Chromatography Mass Spectrometer (GCMS) - A very powerful tool in the analysis of drugs, toxic substances, explosives and other compounds. It can be used for qualitative identification of the substance present as well as quantitative for the determination amount of the susbtance present.

4.    Fourier-Transforminfrared Spectrophotometer((FT-IR) - It identifies organic sustances particularly abused drugs and explosive ingredients by means of their characteristics functional groups resembling fingerprints of an individual.
