Analytical Services

BioTriad has a wide range of field sampling and analytical services.  Our fully accredited and certified laboratories offer screenings with state and national certification programs and analytical services using standard test methods and specialty analytical methods that we have developed in-house.


BioTriad provides routine testing and specialty analytical services for various industries and municipal applications.  We regularly provide gas analysis for a wide range of industry sectors, including food processing plants, landfills, refineries, renderers, sewage treatment plants, and wastewater treatment plants.


Air Quality Analysis

We offer indoor and outdoor ambient air testing with services designed to screen for pollutants listed in EPA’s National Ambient Air Quality Standards (NAAQS).

Our air quality control screening includes analysis of a vast array of air pollutants such as ammonia, carbon monoxide, hydrogen sulfide, mildew and mold spores, nitrogen oxides, ozone, particulate matter (dust), sulfur dioxide, etc..


Activated Carbon Analysis

Our analytical services include a number of different tests used to determine the characteristics and adsorption capacity of activated carbon.

These tests are used with air and water filters to determine which carbon is best suited for an application and how long a specific batch of carbon has before it is spent.

Standard ASTM tests include apparent density, ash content, particle size distribution, and the carbon adsorption capacity methods butane, iodine, and methylene blue.


Field / Lab Odor Analysis

BioTriad provides expert olfactory analysis in both field and laboratory applications.

Our field studies include odor investigations, odor mapping, and odor monitoring using field olfactometers and sample-to-lab analysis .

Our laboratory studies involve odor panel analysis for odor classification, odor strength quantification, and odor dilution-to-threshold concentration.



Isopropylamine is an example of one of the amines included in BioTriad's amine gas content analysis group.

Amine Gas

Standard Test Method for Determination of Airborne Amine gas.

Test Method: Gas Chromatography

Sampling Media: Treated Alumina Tube

These nitrogenous compounds are produced by high temperature processes and by microbial decomposition of amino acids. A specially treated sorbent tube is utilized to collect the target amine compounds.

The fully validated method can detect the target amines present at levels as low as 2 μg/m3 (based on a 100-liter sample volume). Sample tubes are desorbed and analyzed by gas chromatography using a nitrogen phosphorus detector.


Propionic Acid

Propionic Acid is an example of one of the organic acids included in BioTriad's carboxylic acid content analysis group.

Carboxylic Acids

Standard Test Method for Determination of Airborne Carboxylic Acids

Test Method:  Acid Derivatization

Sampling Media:  Silica Gel Sorbent Tube

Carboxylic acids (also known as volatile fatty acids or organic acids) are
associated with landfills, wastewater treatment plants and composting

Samples are collected on a treated silica gel tube using a personal sampling pump.

The method involves the derivitization of carboxylic acids, with subsequent analysis by gas chromatography/mass spectrometry (GC/MS).


Methyl Mercaptan

Methyl Mercaptan is an example of one of the gases included in BioTriad's reduced sulfur compound content analysis group.

Reduced Sulfur Compounds

Standard Test Method for Determination of airborne Sulfur Compounds

Test Method: ASTM D 5504-01

Sampling Media: Tedlar Gas Sampling Bag

Reduced sulfur compounds are associated with wastewater treatment,
petroleum refining and pulp and paper processes, as well as landfill,
composting and agricultural activities.

Air samples are collected in Tedlar bags and analyzed by gas chromatography with sulfur chemiluminescence detection.



Ethanol is an example of one of the gases included in BioTriad's VOC content analysis group.

 Volatile Organic Compounds

Standard Test Method for Determination of Airborne VOC’s

Test Method: EPA Method TO-15 75

Sampling Media: Tedlar Gas Sampling Bag

Samples are collected on thermal desorption tubes packed with application specific sorbents.

At the laboratory, the samples are thermally desorbed and analyzed by gas chromatography/mass spectrometry.

Compounds are identified by comparing the spectra with those from the NIST library.
