A Leader in Air Analysis for Over 3 Decades

After three decades as a leader in the air quality measurement field, YORK continues significant investment in equipment and instrumentation to measure volatile organics from soil vapors, vapor intrusion, indoor air, and landfill gas.

Since the late 1990s, YORK has been and continues to provide VOC analysis by EPA Compendium Method TO-15 for numerous public and private clients.

YORK provides a turnkey TO-15 sampling package of certified clean summa canisters, flow controllers, and filters that have been engineered to simplify sample collection in the field. We offer a variety of air sampling analyses using Tedlar bags, summa canisters, and charcoal tubes (see below for more detail).

Air Sampling Services

YORK and has been involved with the analysis of volatile organic compounds (VOCs) in various air matrices since 1982. Early analyses by EPA Compendium methods TO-1 and TO-2 using thermal desorption-GC/MS techniques were employed to characterize VOCs in ambient air and landfill gas.

During the late 1980s through the mid-1990s, YORK was involved in analyzing thousands of ambient air samples in urban environments for VOCs using EPA compendium methods TO-14 and TO-14A. The YORK mobile air quality laboratory trucks traveled all over the country.

Importance of Air Analysis

Recently, there has been a resurgence in air monitoring including indoor air quality, sub-slab soil vapor, and soil vapor extraction wells analysis in support of regulatory initiatives such as NYSDEC DER-10 and other state-specific report formats.

Soil Vapor Intrusion (VI) studies have become more common and are being mandated in many commercial property transfers. In fact, closed sites are being reopened to examine SVI potential.

These initiatives have raised the bar for air VOC analysis in the sense that the limits of detection required to meet regulatory needs are on the order of 0.25 – 1.0 ug/m3 (0.05 to 0.5 ppb depending upon the compound of interest).

YORK has made significant investments to meet these regulatory requirements and provide a turnkey solution for particular programs with:
  • Increased inventory of inert Summa™ passivated Silonite canisters
  • Various sample flow controllers to meet from 1 hour to 24 hours to meet sampling needs.
  • Automated Summa Canister Cleaning systems
  • Three Stage microscale purge/trap systems for sample introduction into GC/MS systems for TO-15 analyses
  • Multiple Gas Chromatography/Mass Spectrometry Systems (GC/MS) Systems including simultaneous SCAN/SIM Agilent 7890GC/5975C-MS system
  • Strategic partnering with instrument manufacturers to maximize technical parameters
  • LIMS system to produce a myriad of fully automated Electronic Data Deliverables (EDDs) including EQuIS, EZ-EDD, NJDEP, and NYSDEC Environmental Information Management System (EIMS) Equis among more than 100 other formats from simple excel to more complex Staged EDDs.
  • Fully automated data packages for validation including NYSDEC ASP B-Like, CTDEP RCP, and EPA CLP-Like.
