Air Toxics Ltd. New Products

NCASI 99.02

FOLSOM, California -- May 1, 2004 -- Air Toxics Ltd. introduces the addition of NCASI 99.02 to our list of services. NCASI 99.02 is a canister/impinger method designed for the analysis of a select group of volatile organic compounds in air emissions from stationary sources at wood product facilities. The interest in this method has increased greatly since the plywood MACT controls were finalized. The method itself is composed of four different sections; a colorimetric analysis of formaldehyde, a canister analysis by GC/FID, an aqueous analysis by GC/FID and a canister analysis by GC/MS. At Air Toxics Ltd, we have the capability to perform this method on a large or small scale basis and can support your next project. Call us to find out more about NCASI 99.02 and how we can help you.

Redefining 8260b

FOLSOM, California -- January, 14, 2004 -- Air Toxics Ltd. introduces the use of Modified TO-14A methodology for use in 8260b and 8015/8021 applications for vapor phase samples.

Air Toxics Limited has a Modified TO-14A method that characterizes volatile organic constituents by GC/MS/FID. The mass spectral analysis provides the confirmation of BTEX compounds and halogenated VOCs while the FID provides the analysis of total petroleum hydrocarbons (TPH) via a proven vapor phase method.

Data defensibility is ensured by incorporating QC requirements common for the Toxic Organic (TO) compendium of methods written specifically for vapor phase analysis. Why use soil and water methodology to analyze vapor phase samples, when a more relevant and reliable vapor method is available? The EPA TO- series of methods was written specifically for air analysis.

The standard product offering includes:

GC/MS analysis for a standard reporting list of 37 VOC compounds at 5 ppbV reporting limits.
GC/FID analysis of TPH.
Vapor phase standards used for calibration...not liquid standards made in methanol.
Samples analyzed on systems specifically designed for vapor samples.
Standard 5 day Turn Around Time (TAT)

Extraction Improvements

FOLSOM, California -- January, 15, 2004 -- Extractions fifty times faster….that’s what ATL’s new extraction technology can do for you. ATL now has the capability to extract samples using high pressure fluid extraction technology with the Dionex Accelerated Solvent Extractor (ASE). The traditional method of extracting semivolatile compounds relies on a soxhlet extraction which requires cycling large volumes of solvent through the sample media over an 18 hour period. In contrast, the ASE extracts samples under high pressure and elevated temperature. Benefits for using the ASE include:

Faster Turn Around Time	What once took 18-24 hours now can be done in 20 minutes. This means you can have data in your hands as quickly as the same day we receive your sample.
Commitment to Quality	ATL has performed extensive extraction efficiency testing to verify that there will be no loss in quality from using the accelerated extraction versus 18 hour soxhlet extraction.
Complete Automation	Less sample manipulation and more consistent extraction conditions maximizes data precision.
Environmentally Friendly	Much less solvent is required to extract samples using this new technology, allowing those of us working in the environmental industry to be friendlier to the environment.
Cost Savings	If it’s faster and more efficient, you can bet that it saves money too, and this cost savings will be passed onto you.
EPA approved technology	Accelerated solvent extraction is a promulgated method in EPA SW-846 Method 3545.
ATL utilizes the ASE to extract samples for the following methods: TO-4/TO-10A Polychlorinated Biphenyls TO-13A Polynuclear Aromatic Hydrocarbons Other extractable methods
ATL has a history of providing industry-leading service. Much of what makes us special is our dedication to staying on the cutting edge of the environmental industry through the development and application of new technologies.
