Mobile Laboratory Facility


Mobile LaboratoryIn addition to our in-house laboratory facilities, CleanAir has a fleet of trailers and trucks that can provide a dedicated, fully-equipped on-site lab for wet chemistry, gas chromatography, FTIR and Continuous Emission Monitoring (CEM) systems. Regardless of location, our mobile laboratories can be transported to your testing site.

A dedicated wet lab speeds sample turnaround time and virtually eliminates problems due to sample degradation or loss.

Delays resulting from sample train contamination or overloading absorbing solutions are minimized due to rapid detection of these problems while the test crew is still deployed at the testing location.

In addition, air toxics can be analyzed using an on-line system such as a gas chromatograph or gas monitoring system.

Other benefits gained from real-time data include:
• Recovering valuable materials lost during the process
• More accurate emission inventories and factors
• Optimizing process emissions to achieve top performance
• Pinpointing contaminant sources in a multi-source facility
• Improving control of air quality in the workplace

Gas Chromatography
On-line gas chromatography is used to generate real-time compound speciated data. Our Analytical Services team has a wide variety of expertise in direct-sampling and quantifying specific compound emissions using gas chromatography. Various compounds are speciated and quantified using the following test methods:

Method 15
Utilized to measure the emissions of reduced sulfur compounds from tail gas control units of sulfur recovery plants, hydrogen sulfide in fuel gases and where specified in other applicable subparts.

Method 16
This method determines total reduced sulfur compounds from recovery furnaces, lime kilns and smelt dissolving tanks at kraft pulp mills and fuel gas combustion devices at petroleum refineries.

Method 18
Speciated gaseous organics emitted from industrial sources are determined by this method.

Fourier Transform Infrared (FTIR) Spectroscopy
Clean Air has the capability to perform Fourier Transform Infrared (FTIR) Spectroscopy for the analysis of various gaseous emissions from stationary sources. The test methods using FTIR for analysis are Method 320 and 321. We have the necessary field experience with the FTIR as well as the knowledge and skill to create new FTIR standards, test protocols and methods.

Method 320
This method determines compound-specific concentrations in a multi-component vapor phase sample in a closed-path gas cell. Specifically, organic or inorganic compounds which absorb energy in the mid-infrared spectral region (about 400 to 4000 cm-1). A computer program is used to analyze infrared spectra and report compound concentrations.

Method 321
This method determines hydrogen chloride (HCl) concentrations in a multi-component vapor phase sample in a closed-path gas cell. Specifically inorganic compounds which absorb energy in the mid-infrared spectral region (about 400 to 4000 cm-1). Computer software is used to analyze infrared spectra and report HCl concentrations.
