Alkyl PAH by EPA Method SW8270D-SIM

Analytical Resources has extended its expertise with the SW8270D-SIM (Selected Ion Monitoring) method by testing for a wide range of substituted Alkyl PAH (Polyaromatic Hydorcarbons) in sediments. The Alkyl PAHs range from C1-Decalin to C3-Dibenzo(a)anthracenes. Samples can also be simultaneously analyzed for a standard list of target PAHs. Reporting limits for the Alkyl PAHs can be as low as 50 ppb in sediments depending on percent moisture and screening levels. Please contact a project manager if you have any questions about the method or the analyte list. Pricing for the test can be found here.

EDB/DBCP By EPA Method SW8011

Analytical Resources is now equipped to test for 1,2-dibromoethane (EDB) and 1,2-dibromo-3-chloropropane (DBCP) by EPA Method SW8011. The reporting limit for both analytes is 0.010 ppb in water. If you have any questions regarding this analysis please contact your project manager or use the contact information below. Pricing for the test is available here.

PBDE Congeners

Analytical Resources is pleased to now offer the testing of Polybrominated Diphenyl Ether (PBDE) congeners in a range of environmental samples. PBDE congeners are similar to PCB congeners in that they are resistant to degradation, bioaccumulate in tissue, and are used in a broad spectrum of industrial applications. Monitoring has shown that these chemicals are ubiquitous in the environment and evidence suggest that PBDEs may cause detrimental health effects in animals and humans.

A selected list of PBDE congeners, representing the major components of common technical grades, are analyzed using a GC equiped with dual capillary columns and a electron capture detector (ECD).

Please contact us for a list of target analytes, reporting limits, and pricing.

Oxygenates

Gasoline additives, or oxygenates, are a concern in the environment as they have been found to have contaminated groundwater through leaking underground gasoline storage tanks (USTs). ARI is now testing for an a number of oxygenates, including MTBE, TAME, ETBE, Diisopropyl Ether and tert-Butanol, using volatile GC/MS Method SW8260C. Please contact us to for more information regarding reporting limits and other analytical details.

Now Testing Biodiesel

ARI is now testing for Biodiesel with a 5-day turn around time. Contact us for details.

Low Level Mercury Analysis

Increased public concern with the bioaccumulative affects of Mercury and advances in technology are driving regulatory levels to lower requirements. ARI has validated a modification to the CVAA method to report mercury at 20 parts-per-trillion.

Lower Reporting Limits for TPHG/BETX

We now offer lower detection limits of 0.03 ppm for gasoline and 0.08 ppb for BETX analyses.

Dissolved Methane, Ethane and Ethene

Dissolved gases are often used as indicators of the biodegradation process under anoxic conditions. ARI purchased new instrumentation and validated the RSK-175 method, allowing us to offer RSK-175 with ARI quality and turn-around time.

Semivolatiles by SIM

While there is increasing concern for monitoring compounds at lower concentrations in water, sediment samples with low TOC values or high contaminant levels often make it difficult to meet screening levels. ARI has validated a SIM method for the 'problematic' semivolatiles at approximately 0.1 ug/L levels for waters and 6.7ug/kg for soils/sediments. Solid samples require screening prior to extraction and both matrices require concurrent analysis by full-scan GC/MS. PAH only can be analyzed at 0.01 ug/L in clean waters.

Congener Analysis

Regulatory limits are currently expressed as Aroclors, but factors may dictate that a site be evaluated based on the results of PCB congener analysis. The cost of HR-GC/MS analysis may be prohibitively high and may be inappropriate for initial investigations. As an alternative, ARI will offers Congener analysis using GC/ECD-8082 method.

Tissue Analyses

Mercury, PCBs, Chlordane, Dioxin or DDT have been the primary constituents responsible for fish consumption advisories in the past. Additional chemicals have the potential to cause adverse effects after release to surface waters due to bioaccumulation in aquatic organisms. In response, agencies are increasing efforts to monitor fish and shellfish contamination and to identify the cause and source of the contamination. ARI has years of experience analyzing Tissues for Butyl Tins, Aroclor PCBs, Chlorinated pesticides, Semivolatile Organics, Pentachlorophenol, metals, Mercury and lipids. New for 2006 are method specific clean-ups to reduce interferences from the matrices and addition of a large capacity grinder for homogenizing larger organisms.
