We provide answers to all the analytical needs of the sector

An emission is the release of polluting substances into the environment. These substances can be emitted by natural sources (volcanoes or forest fires) or by humans through factories, vehicles and other activities. A immission is the concentration of pollutants in the air as a result of emissions. They can be influenced by meteorology, topography and the distance between the emission source and the receptor.

The analysis of both requires a high level of technical expertise that can only be found in a network of laboratories such as Eurofins Environment Testing Spain.

Our Analysis:

Our team specializes in the following analyses of atmospheric emissions and immissions:

Gas analysis

Analysis of inorganic compounds

Analysis of volatile organic compounds

Metal analysis

Total particulate matter, PM10 and PM2.5 analysis

Gas analysis:

Medición de muestras de biogás o muestras de aire tomadas en bolsas de muestreo para análisis: metano (CH₄), hidrógeno (H2), mercaptanos (RSH), siloxanos, compuestos orgánicos volátiles, aminas (NH2R) y otros contaminantes.

Analysis of inorganic compounds:

Measurement of the concentration of gases in air such as Hydrochloric acid (HCl), Nitrogen oxides (NOx), Sulfur oxides (SO₂, SO₃), Hydrofluoric acid (HF), Ammonia (NH3), Hydrogen sulfide (H₂S), among others.

Analysis of volatile organic compounds:

Measurement of the concentration of volatile organic compounds in the air, such as BTEX, aldehydes, PAHs and other organic chemical compounds.

Metals analysis:

Measurement of metal concentrations in air, and in atmospheric depositions. Individual metals, metal packages, and metal speciation (Cr VI).

Analysis of total particles, PM10 and PM2.5:

Measurements of total particulate matter in emissions, PM10 and PM2.5 particles in immissions and settleable particles in non-channelled emissions.

Supply of sampling materials

Eurofins Environment Testing Spain is one of the few laboratories that supplies sampling materials. Our organization is characterized by the following:

We adapt to the needs of our customers

Strict compliance with delivery deadlines

Our emission and immission analysis techniques

The analysis of emissions and immissions is done with a variety of techniques and methodologies, depending on the pollutant and the nature of the sample.

At Eurofins Environment Testing Spain we are specialists in the following types of techniques:

Gas chromatography

Different types of detectors are used: mass (MS), flame ionization (FID), electron capture (ECD) and thermal conductivity detector (TCD).

High performance liquid chromatography

Separation of organic compounds according to their chemical properties, identification and quantification by ultraviolet and fluorescence.

Ion chromatography

Separation of inorganic contaminants based on their properties by electrical conductivity.


Quantification of metals in a sample by inductively coupled plasma optical emission mass spectrometry (ICP-MS, ICP-OES).

Mass Spectrometry (ICP-MS) – High Performance Liquid Chromatography (HPLC)

Identification and quantification of metal species such as Cr VI in air samples.


Identification and quantification of the inorganic components of a sample as a function of their absorbed radiation.


Quantification of the mass of particles in a sample by weighing them on highly sensitive balances under strictly controlled conditions of temperature and humidity.
