  • Simulated Distillation (SimDist)
  • Elemental Analyzer (EA)
  • High-Performance Liquid Chromatograph (HPLC)

Determination of paraffins, isoparaffins, olefins, naphthenes and aromatics by carbon number in naphtha and Gasoline.

Gas Chromatography (GC)

Whole Oils, Crude oils and Petroleum Products.

Gas Analyzer

Compositional Analysis for LPG, Refinery Gases and Natural Gas

Co/Co2 Analyzer

Determination of trace level analysis of carbon dioxide/monoxide in various hydrocarbon matrices as well as pure gases like Oxygen, Hydrogen, Helium and Nitrogen.

Simulated Distillation (SimDist)

For determination of boiling distribution of petroleum fractions or petroleum products using gas chromatography.

Offers a range of “SimDist” applications to determine True Boiling Point data of petroleum streams up to 750Co, based on the CP-3800 GC.

Elemental Analysis (EA)

Determination of Carbon, Hydrogen, Nitrogen Sulfur Oxygen (CHNS-O) in crude oils and solid organic samples.

High Performance Liquid Chromatography (HPLC)
  • To determine the Fatty acid in waters
  • To determine Poly Aromatic Hydrocarbons (PAH) in Waters
  • Any other application
Gas Chromatography Mass Spectrometer (GC-MS/MS)
  • Environment determination of volatiles organic compounds in wastewater, tap
  • water, and solids
  • Inorganic Geochemistry applications
  • Determination of naphthenic acid in crude oils, organic acids, alcohol and PAHS

Spectrometric Analysis Lab.

Different spectrometric equipments:

Atomic Absorption Spectrophotometer (AAS)

Trace metals in crude oils, petroleum products, water and other samples by Atomic Absorption Spectrometer (AAS)

Inductive Coupled Plasma (ICP-OES)
  • For Environmental, Chemical and Industrial Applications.
  • Determination of Metals in Lubricating Oils, Crude Oils and Petroleum Products.
  • Determination of Metals in different Water and Rock Samples.
X-ray Fluorescence (XRF)

Determination of elements in gases, liquid and solid samples (water, petroleum products, rocks and cement).

Direct Mercury Analyzer

Spectrometric Analysis Lab.

Following up implementation of calibration and maintenance plans in PLRS to cope with the ISO 17025 requirements and to assist in accomplishing the required quality levels of measurement data that satisfy customer requirements.
