Centek Laboratories, LLC Air Testing Laboratory has extensive experience sampling and analyzing a broad range of air contaminants including, but not limited to, Volatile Compounds, Air Toxics, and Hazardous Air Pollutants. In fact, Centek Laboratories, LLC opened it doors in 2003 working with New York State to develop and implement the NYSDOH Soil Vapor Intrusion Guidance. To this day, the NYSDOH Vapor Intrusion Guidance is regarded as one of the most recognized documents relevant to Vapor Intrusion Sampling and Analysis.

Centek Laboratories, LLC has the analytical expertise and project management capabilities to support a variety of soil vapor intrusion and indoor air investigations.

Centek offers specialized sampling programs to fit your projects budget and sampling / analytical goals.

• Soil Gas Vapor Intrusion Testing
• Indoor Air Vapor Intrusion Testing
• Ambient Air Testing
• Helium Leak Testing
• Soil Gas Tracers
• Appropriate Methods and Procedures

Subsurface Vapor Intrusion has become a topic of particular interest due to factors including:

• Increased recognition of Vapor Intrusion as an important exposure pathway
• Greater emphasis on the remediation of contaminated sites that introduce harmful substances into indoor air
• The recent publication of key state and federal Vapor Intrusion Guidance documents

Centek Laboratories, LLC is accredited by both NELAP and AIHA-LAP, LLC (ISO/IEC1725) to run EPA Method TO-15, as well as several other local, state, and federal programs. Most current guidance documents recommend the use of EPA Method TO-15. Contact the laboratory for our most up to date certification information.

Centek Laboratories, LLC are expert analysts of fuel hydrocarbons in air from gasoline, diesel, oil, mineral spirits, bunker fuel, jet fuel etc. and other specific compounds of concern. Specific target compounds for analysis include, but are not limited to benzene, toluene, ethylbenzene, xylenes, fuel aromatics, fuel oxygenates (MTBE, ETBE, TAME, TBA, DIPE), and chlorinated solvents (PCE, TCE and their breakdown products such as vinyl chloride, 1,1-DCE and others). In addition to Centek’s TO-15 list is the ability to scan for over 170,000 additional hazardous compounds within the air matrix.

Our state-of-the-art instrumentation, in many cases, is specifically designed and modified by our technical staff to achieve low detection limits while maintaining the highest quality data for your Vapor Intrusion Projects. Centek Laboratories, LLC has experience working with large conglomerates, government agencies, as well as smaller private firms and homeowners.

The age-old saying of “One man’s garbage…Is another’s mans Gold” is becoming true in the reclaiming of Biogas from landfill operations. While we still depend on fossil fuels as our primary energy resource, the use of newer and cheaper energy sources such as landfill gas is increasing throughout the world today.

Biogas, and particularly landfill gas, or LFG, is usually heavily contaminated with VOCs (Volatile Organic Contaminants). VOC levels can exceed 1,000 ppmv, and are usually at least 50 ppmv, requiring removal by specialized treatment equipment so LFG can be used as a reliable fuel. Treatment systems for heavily contaminated biogas utilize media that is regenerated on a continuous basis to prevent siloxanes, halogenated VOCs, and other harmful VOCs from entering combustion equipment or being released to the atmosphere.

Organosilicons cause most of the damage to Internal Combustion (IC) engines, microturbines, boilers, and SCR catalysts. We measure the organosilicon content, major gas components (methane, nitrogen, oxygen, carbon monoxide & carbon dioxide), complete VOC (volatile organic contaminant) spectrum, plus organic and inorganic sulfur of your biogas. From this analysis, our biogas molecular scientists can determine the fouling potential (from silica formation) and treatability of your biogas.

Along with our industry partners, we can provide you with test results. We can develop a complete gas profile and determine the proper treatment processes needed to meet even the most stringent biogas specifications for use as a fuel. These treatment methods can include:

• Siloxane (and other organosilicons) Removal
• Moisture Removal
• Sulfur Removal
• Methane Content Upgrade
• System Maintenance

Are You Ready for the New V4 IAQ Test?

TO ESTABLISH BETTER QUALITY INDOOR AIR IN THE BUILDING AFTER CONSTRUCTION AND DURING OCCUPANCY.

The New V4 requirements are as follows:

Air testing now worth (2 points)

After construction ends and before occupancy, but under ventilation conditions typical for occupancy, conduct baseline IAQ testing using protocols consistent with the methods listed in Table 1 for all occupied spaces. Use current versions of ASTM standard methods, EPA compendium methods, or ISO methods, as indicated. Laboratories that conduct the tests for chemical analysis of formaldehyde and volatile organic compounds must be accredited under ISO/IEC 17025 for the test methods they use. Retail projects may conduct the testing within 14 days of occupancy.

Demonstrate that contaminants do not exceed the concentration levels listed in Table 1.
