Air pollution

Detecting and diagnosing poor air quality can be a significant challenge. Emissions Analytics’ laboratory services apply the powerful analytical technique of two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GCxGC-TOF-MS).

Pollutants identification

Utilising this industry-leading scientific approach, we are able to handle complex matrices, detect a wide range of contaminants, volatile organic compounds (VOCs, including benzene, toluene, and phthalates), semi-volatile organic compounds (SVOCs, including aldehydes) and persistent organic pollutants (POPs) in air and gas samples.

Source identification

Based upon the contaminants found, we can then begin to identify potential sources of the pollution. This is a consultative process, and Emissions Analytics provides support throughout.

Applications

1. Ambient air monitoring

2. Indoor air quality assessment

3. Industrial emissions monitoring

Our advantage: GCxGC-TOF-MS vs. GC-MS

• Enhanced separation: two-dimensional chromatography provides superior separation power, allowing for the resolution of complex mixtures.

• High sensitivity and selectivity: time-of-flight mass spectrometry provides excellent sensitivity and the ability to detect and identify trace-level contaminants.

• Comprehensive analysis: together, the techniques are capable of analysing a wide range of compounds in a single run, reducing the need for multiple analytical methods.

• Identification and quantification: many unknown compounds can be identified, their structure elucidated, and concentrations quantified.
