Instrumentation

The staff of AAC is supported by a wide variety of state-of-the-art laboratory equipment and supplies in order to meet your analysis needs. We are confident that our instrumentation can meet and/or exceed the analytical requirements as specified in each of the methodologies that we provide services for.

We have three custom built GC/FID Total Carbon Analyzers (TCA) for EPA methods 25, 25C & 25D as well as for SCAQMD methods 25.1 and 25.3. In addition, we have recently finished modifying our custom built trap burning system which now allows for cold purging to the original sampling tank minimizing CO2 interference and low bias from the loss of light end condensables.

AAC currently utilizes several GC-SCD’s for speciated sulfur compounds analysis, many of which are specifically tuned for various industries. Our newest system was custom built to detect sub ppbV levels for trace level monitoring and ambient air analysis, far exceeding those requirements for ASTM D-5504 and SCAQMD 307.91. Our second system is specifically geared for LNG/LPG, landfill and biogas samples containing elevated levels of these compounds.

AAC has several GC/MS systems capable of providing low-level TO-14/15 analysis with reporting limits as low as 200 pptV for full SCAN mode and 10 pptV using SIM mode. A few of these systems are also equipped with FID’s for trace level C2 - C12 speciated Hydrocarbon analysis by EPA method TO-12/PAMS Protocol. These systems also offer various other AAC custom developed methods such as our Siloxanes and speciated Sulfur compounds methods.

AAC also has several GC/FID’s and HPLC’s as well as an IC and TOC analyzer utilized for the analysis of Carbonyl’s, PAH’s, Isocyanates, Alcohols, Solvents, Inorganic & Organic Acids, Amines and various other custom VOC’s.

Daily operation and calibration of our equipment allows us to maintain instrumentation that is always immediately available for your analysis needs including rush projects.
