Technical Approach

The experienced staff of scientists employed by Nordon Corporation operate custom built mobile laboratories designed for efficient, real-time sampling of emissions from stationary sources with the capability to provide results the day of the emission test. Our mobile laboratories are efficient, effective tools to show compliance with air pollution state and federal requirements, and for process engineers, they are learning tools to determine ways of reducing and controlling source emissions to save clientele time and money.

Each mobile laboratory has specially designed sample manifolds with the capability of delivering wet or dry emission samples dependent of the requirements of the analysis equipment. The continuous analyzers are rack mounted to protect and maintain the integrity of the equipment. Each analyzer rack is large enough to add different types of analyzers for single source sampling or two sets of duplicate analyzers for dual source sampling. Calibration and support gases are rack mounted for safe transport and storage. The results of sampling are recorded in each trailer by data acquisition systems customized to the needs of our clientele.

The mobile laboratories are either trailers (16-foot and 12-foot) or vans. All mobile laboratories can be set up for dual source sampling. The larger 16-foot trailers provide expanded analytical capabilities including gas chromatography as well as additional room for manual sampling method recovery or on-site wet chemistry analysis. The vans are specially designed for emission source sampling with the use of fourier transform infrared spectroscopy (FTIR).

Nordon Corporation incorporates the best technologies into its mobile laboratories. An example is our use of FTIR. Newer and changing EPA rules are now allowing the use FTIR as approved analytical equipment. Basically, an FTIR allows the analysis of typical combustion analytes of interest (NOx, CO, and VOC) as well as many other analytes real-time using one analyzer. With the assistance and training of leading figures in the FTIR equipment field, we have streamlined the quality assurance, data reduction, and reporting procedures. Where applicable and convenient, the FTIR is becoming the preferred analysis tool.

The FTIR can also analyze formaldehyde and ammonia concentrations real-time. Other formaldehyde and ammonia sampling and analysis techniques are equipment intensive and time consuming, and samples are usually analyzed off-site using wet chemistry analysis. A determination of compliance for these compounds may be available days after the sample collection. The FTIR allows us to provide the client with information on the compliance status of formaldehyde and ammonia emissions real-time which may eliminate unnecessary equipment maintenance and limit regulatory exposure. With our dual FTIR capabilities, real-time catalyst formaldehyde reduction efficiency is available to our clients.
