Chemical Analysis Unit

CNH Analyzer

Analyses are performed on a Perkin Elmer Elemental Analyzer model 2400. The Elemental Analysis Service performs quantitative analyzes of solid and viscous liquid samples for the content of C (carbon), H (hydrogen) and N (nitrogen) measured as a percentage of the weight.

TOC Analyzer

The total organic carbon (TOC) analyzer is used to determine the Carbon content in fluids and semi-solid samples. This Service performs the quantification of the organic carbon (OC) and black carbon (BC) content of atmospheric particulate material retained in quartz fiber filters.

Arsenic Speciation Analyzer

This Service carries out arsenic speciation (arsenite, arsenate, monomethyl arsenic and dimethyl arsenic) by high performance liquid chromatography (HPLC) coupled to atomic fluorescence spectroscopy (AFS).

Jasco PU-2080 HPLC, with Rheodyne 7125 injection valve, coupled to PS Analytical Millenium 10.33 atomic fluorescence spectrometer.

HRMS LC-MS/MS QTOF Spectrometer

Mass spectrometry data can be acquired on a Bruker Compact QTOF spectrometer, equipped with an autosampler and UHPLC unit. It provides high resolution mass spectral data (HRMS) and also the possibility to isolate and analyze ionized species (MS/MS) . It is used for a wide range of applications, compound identification, quantification and characterization, and for synthetic chemistry support.

ICP-MS Analyzer

Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique that can be used to measure elements at trace levels.  The main advantages of this technique lie in the high precision, low detection limits and low economic cost, analyzing most of the elements and isotopes of the Periodic Table simultaneously.

ICP-OES Analyzer

Inductively Coupled Plasma optical emission spectrometry (ICP-OES) analysis provides identification and detection of trace metals contents in chemical samples. This ICP technique provides extensive trace metals testing and analyses.


The Agilent 5977B GC/MSD is in the series of most trusted single quadrupole GC/MS instruments. It is ideal for different applications such as environmental, chemical, petrochemical, food, forensic, pharmaceutical, and material testing.

Ion-Exchange Chromatography

Ion-exchange chromatography or ion chromatography is used for analysing ions in parts-per-million (ppm) from aqueous samples. Common anions are fluoride, chloride, nitrate, nitrite and sulphate; and common cations are sodium, potassium, ammonium, lithium, calcium and magnesium. Ion chromatography allows the separation of ions and polar molecules based on their charges.

Gas Chromatography (GC-MS)

GC is one of the most widely used analytical techniques in research laboratories since its qualities include its speed, precision and accuracy. GC can be coupled with mass spectrometry (MS) in a mass spectrometer chromatograph, by which complex mixtures of chemicals may be separated, identified and quantified.
