GASERA ONE SHED

Evaporative emissions testing for automotive

Selective simultaneus monitoring of ethanol and methanol
Sensitivity in the ppb-region for all measured gases
Highly selective against ambient background gases and other VOC’s

DIRECT MONITORING OF EVAPORATIVE EMISSIONS WITH GASERA ONE SHED

Evaporative losses from the fuel system are tested for vehicle certification. GASERA ONE SHED allows direct monitoring of evaporative emissions as part of the qualification testing procedures for vehicles. The GASERA ONE SHED’s photoacoustic technique is approved by the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).

Three testing options with GASERA ONE SHED

Sealed Housing for Evaporative Determination (SHED)

The Sealed Housing for Evaporate Determination (SHED) test monitors evaporative emissions in the automotive industry. Photoacoustic IR spectroscopy (PAS) is used for SHED testing and it is approved by the United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).

Refrigerant emissions

Quantitative leakage testing on mobile A/C equipment for verifying compliance with international standards. The photoacoustic technique provides an accurate and rapid result with a high rate of repeatability, even at very low emission rates, such as those that occur at low to moderate temperatures.

Tail pipe testing

The GASERA ONE SHED can be configured for exhaust gas analysis through bag sampling allowing direct quantitative measurements of trace pollutants in exhaust.

GASERA ONE SHED photoacoustic multi-gas analyzer is based on combining ultra sensitive cantilever enhanced photoacoustic detection technology with a widely scanning external cavity quantum cascade laser source operating in Mid-IR fundamental spectral absorption range.

This combination provides an unmatched sensitivity for ppb-level monitoring. Due to the wide scanningrange of four gases can be measured selectively and simultaneously.
