Dallas, Houston, Austin Indoor Air Quality (IAQ) Testing for VOCs, SARS-CoV-2 / CoViD-19, Bacteria, Mold, Formaldehyde, Organic Dust

214.912.4691

ScanTech now offers rapid SARS-CoV-2 virus testing in both air grab and surface swab sampling along with bacterial level (relative biological cleanliness for hospitals and other facilities) using an ATP luminometry. We can also check the following key indoor air quality level indicators and can give rapid answers onsite – no waiting for lab results in most cases. (radon testing and mold / dust characterization sampling are some exceptions)

*EFFECTIVE January 1st, 2019 ScanTech will no longer perform residential testing OR consulting for homeowners / tenants – all services are COMMERCIAL ONLY. Here is a page for resources to common questions – CLICK HERE.

CONTACT US

For your Indoor Air Quality Testing Quote please contact with the following information:

1) Physical address of the site including the company name and the nature of your business (office, industrial, manufacturing, chemical, etc.)

2) The narrative of your concern (dust, mold, ventilation, a specific contaminant, biological agents, etc.)

3) General layout of the floors involved and the square footage to determine the number of test points. It does not have to be an MPE CAD drawing, but more than a fire escape plan if possible

4) How soon you need the survey

5) Path to payment (check, credit card, etc.) and what vendor vetting process is involved if any or if your company directly pays out

6) If you are a 3rd party (General Contractor, Engineering / Forensic Firm, etc.) looking to serve another end client

 

We have been testing formaldehyde in the Dallas – Fort Worth area for years and DO NOT require cutting into your laminate floor or charge $525 – $600 per sample and then make you wait for results like some laboratories.

BASIC INDOOR AIR QUALITY (IAQ) INSPECTION

• Formaldehyde (HCHO) – non-destructive testing – immediate results
• VOCs (Volatile Organic Compounds) including benzene, toluene
• Carbon Dioxide (CO2) – general measure of ventilation quality
• Carbon Monoxide (CO) – deadly gas
• Respirable Dust Particles in PM2.5 (fine) and PM10 (coarse) size regimes
• Oxygen Levels (where applicable)
• HEPA Filtration, MERV rating and other air purifier efficiency metrics
• Relative ventilation levels – critical to know in newer buildings that are built “tight” for energy efficiency

 

SPECIAL / OPTIONAL AIR QUALITY SERVICES

• Mold Assessment Consulting (MAC licensed by the State of Texas)
• Radon Rn-222 Levels (known alpha emitter lung carcinogen)
• Forensic laboratory field testing (air grab, bulk, tape lift, swab / wipe, etc.) where required for bacterial, viral issues
• Particulate counts by size channel: 0.3 um, 0.5 um, 1.0 um, 2.5 um, 5 um, 10 um as well as PM 2.5 and PM 10
• Ozone gas levels and hydrogen sulfide (associated with sewer gas leaks)
• Positive / negative air pressure checks to confirm tendency for contamination

along with atmospheric factors such as:

• Temperature
• Relative Humidity
• Barometric Pressure (to judge whether the structure is under positive or negative pressure with respect to the outside air)

and for commercial applications such as HVAC metrics, we can also measure:

• Absolute Humidity
• Dew Point
• Mixing Ratio
• Vapor Pressure
• Heat Stress (WBGT) & Heat Index Factors

(my personal favorite is Icelandic, very refreshing with a pH of 8.4 which is somewhat alkaline and has a very slight, sweet mineral taste)
