ENVIRONMENTAL LABORATORIES: CHEMICAL AND OLFACTOMETRIC

CHEMICAL LABORATORY

The Chemical Laboratory performs tests on air, water, soil, waste, emissions and occupational hygiene.

The official list of tests is available from the laboratory or the Databank section of the Accredia website, by entering accreditation number 1517 in the “testing laboratories page.

The Chemical Laboratory has the following analytical sections: Chemistry, Chromatography, Spectroscopy and Microscopy.
Chemistry: sample preparation and chemical analysis
Extraction of phenolic compounds (preparation for gas chromatography)

In this area, the sample is prepared (water, soil, waste) to ensure the analytical chemistry tests are performed under optimum conditions, delivering high-quality results.

 

This section also takes direct readings of the chemical-physical parameters of waters (wastewater, drinking water, groundwater and seawater), soils (agricultural, from polluted sites or remediated) and industrial waste, as well as readings for emission and occupational health monitoring.

Chromatography
GC-MS (gas chromatography mass spectrometry) interfaced with P&T (purge and trap)

The chromatography section performs highly accurate qualitative and quantitative analyses on all types and classes of organic compounds to detect their presence, even in traces, in various environmental compartments.

The compounds are analysed either individually or by class using the latest and most sophisticated purification and detection systems.

 

With the support of SARTEC’s other departments, the laboratory can operate on solid, liquid and gaseous samples, as collected or after extraction and/or purification.

Spectroscopy and microscopy
ICP-OES (inductively coupled plasma optical emission spectroscopy)

This sector has equipment for atomic and molecular spectroscopy, X-ray fluorescence and optical microscopy.

During processing, the most appropriate technique is used, for example for quantitative determination of the compounds in solutions (spectroscopy) or solid samples (microscopy).

 

Spectroscopy (e.g. NMR, UV, Raman, near/mid-infrared) is a fast and low-cost alternative for estimating the physicochemical properties and refining yields of crudes and their mixtures on-site, using chemometric techniques.

OLFACTOMETRIC LABORATORY

We have the only Olfactometric Laboratory in Sardinia,
with state-of-the-art instruments for measuring odour emissions from any type
 of sources.

Since 2011, the Olfactometric Laboratory has performed non-conventional monitoring of odour emissions from complex industrial sites, such as oil refineries.

The laboratory meets all the requirements of European technical standards. Its sampling and testing equipment includes GC/Mass/SCD for detection of trace volatile organic compounds and organosulfur compounds.

The Olfactometric Laboratory conforms to the requirements and procedures of UNI EN 13725:2004 “Air Quality – Determination of Odour Concentration by Dynamic Olfactometry”.

The OLF LAB’s olfactometry chamber

The Olfactometric Laboratory has a Scentroid SS600 dynamic dilution olfactometer. Using ad hoc software, this instrument mixes the sample air with clean diluting air, then sends it to the six stations of the panellists performing the odour analysis.

The panellists analyse the samples, assessing odour concentration and threshold, pleasantness or unpleasantness (hedonic tone) and perceived intensity.

A specific mathematical model is used to determine the rate of spread of odour-emitting substances over a given area, to obtain a predictive view of the phenomenon.
