The Air Measurement Specialists

Environmental Analytical Service (EAS Inc.) was founded in 1985 and has specialized in ambient air, indoor air, and source gas analysis for over 20 years, and was the first dedicated specialty air testing laboratory in the country. EAS uses only EPA, California Air Resources Board (CARB) and other agency approved methods for all routine analysis, and has an extensive NELAP Quality Assurance program to guarantee the highest quality data. For special analytical projects, EAS has full capabilities for method development and evaluation. EAS participated in the EPA Special Analytical Services (SAS) program and has been audited by EPA and by the DOD under the Navy Clean  program specifically for air testing services.

The personnel at EAS are all dedicated to providing quality analytical data for any size project. Past projects range in size from one grab sample to projects involving in excess of one thousand samples collected over a several month period. One of the advantages of EAS is that your project gets the research experience of Dr. Steven Hoyt who has over twenty years experience in method development, measurement, and interpretation of ambient air data. Supporting Dr. Hoyt is his staff of well trained technicians whose commercial laboratory experience means the project will be run with a completely documented Quality Assurance program.

COMPANY DESCRIPTION

Environmental Analytical Service, Inc. (EAS) was founded in 1985 by Dr. Steven D. Hoyt, and is a privately held California Corporation, whose primary mission is to provide high quality Air Measurement Testing. EAS is located in a modern facility and employs a staff of qualified professionals that are trained in air and gas analysis.

EAS Corporate Mission Statement:

We at Environmental Analytical Service, Inc. are a well trained team dedicated to providing quality state of the art analysis to assist our clients in meeting their project objectives.

Corporate Goals:

• Assist the client in selecting the correct standard analytical method or developing a modified method to meet the project objectives, rather then limit the project objectives based on available methods.

• Provide high quality analytical data backed by an extensive QA/QC program.

• EAS will provide a standard turnaround time of 10 working days for the final report, and 5 to 7 days for preliminary results on routine analytical tests.

FACILITIES

Environmental Analytical Service, Inc. is located in a modern 5000 sq foot facility that is dedicated to ambient air and gas analysis. All equipment at EAS is dedicated to air and gas analysis.

Instrumentation Room

EAS has a 2000 sq foot instrumentation room that has been specially designed to provide a solvent free environment to achieve the low MDL values that EAS is known for. The room has five GC/MS systems with full data processing and NIST mass spectral libraries, five gas chromatographic systems equipped with FID, FPD, PID, and ECD detectors, and one GC/TCD that is dedicated to source/refinery process gas analysis and permanent gas analysis. A complete line of concentrators from an automated cryogenic concentrator to purge and trap units are available. One gas chromatograph (GC) with FID detectors is dedicated to methane, non-methane hydrocarbons, and EPA Method 25.

Chemistry Lab

The chemistry lab is located next to the analytical lab, but is in a separate unit to avoid solvent contamination of the instrumentation room. The chemistry lab is equipped with hoods and extraction area for handling semi-volatile sample extractions. The chemistry lab also houses the HPLC system used for phenols and aldehydes.

Sample Control/Sampling Equipment

The Sample Control area houses the EAS computer LIMS system and houses the 400 plus SUMMA canister inventory as well as other sampling equipment. Samples are shipped and received in this area. All canisters are tracked by the EAS computer system, and all samples are logged into the LIMS system as they are received. This room also houses the canister cleaning system and the pressurization system for measuring, pressurizing, and adding surrogate standards to canisters.
