Sunset Labs

Carbonaceous aerosol data can be central to understanding combustion sources, urban air pollution, wildfire smoke, diesel emissions and workplace exposure. Sunset Laboratory has specialised in OC/EC aerosol analysis for decades, with instrumentation used across government, academic and commercial monitoring programmes. Its analysers are designed to produce consistent, defensible results while helping teams manage the practical demands of routine sample processing and field deployment.

Sunset Laboratory systems use thermal-optical methods to separate and quantify organic and elemental carbon collected on quartz filters. This approach provides the detail needed to distinguish carbon fractions, investigate pollution sources and compare results across established monitoring networks. For consultants, that means stronger evidence for baseline surveys, impact assessments, compliance-related investigations and client reporting. For researchers, it means a robust platform for repeatable aerosol characterisation.

Sunset equipment is suited to established analytical approaches including NIOSH Method 5040, IMPROVE protocols and EUSAAR 2. Choosing an instrument aligned with recognised methods can simplify method development, support data comparability and strengthen confidence in reported results. Whether you are building a new particulate analysis capability or maintaining an established programme, the right configuration helps keep workflows clear from filter handling through to final data review.

The Sunset Laboratory range covers laboratory analysers, semi-continuous field analysis and supporting items for carbonaceous particulate sampling and measurement. Select equipment around your monitoring objective: routine analysis of collected filter samples, near-real-time OC/EC/BC data at a field site, or a workflow designed for higher sample throughput. TES can help environmental teams identify the appropriate Sunset solution for their method, sample load and deployment conditions.
