For additional information,
Southwest Research Institute.
Since the late 1970s, Southwest Research Institute
provided unique engineering and analytical services to help the automotive industry
worldwide comply with requirements of the U.S. Clean Air Act.
Using a liquid chromatograph, a
technician evaluates exhaust samples for a number of aldehydes and ketones including toxic
formaldehyde and acetaldehyde.
In addition to monitoring regulated emissions, SwRI helps
manufacturers ensure that emission control devices and engine design elements do not
result in significant increases in unregulated pollutants. SwRI has numerous engine
dynamometer test cells (1 to 60 hp) and several chassis dynamometers equipped with
state-of-the-art sampling systems for both regulated and unregulated emissions, where
engineering teams operate engines and vehicles through a number of transient cycles,
including the Federal Test Procedure.
SwRI analyzes a number of pollutants
including ammonia, formic and acetic acids, and sulfate, using chromatography.
In-house analytical support includes:
- Gas chromatographs equipped with a variety of detectors
- Liquid chromatographs
- Ion chromatographs
SwRI collects samples using a variety of
techniques including impingers, traps, bags, and filters.
Using analytical procedures for more than 20 unregulated
emissions, SwRI evaluates and reports data on such pollutants as benzene, formaldehyde,
acetaldehyde, alcohols, hydrogen sulfide, 1,3-butadiene, and many others.
