ESS Asia Conducts Isokinetic Training for EATC Students

Hanoi, Vietnam – Environmental Source Samplers, Inc. (ESS) continues its growth in the air-testing and environmental air-consulting markets of Southeast Asia. Continuing its multi-year expansion into the networks of the environmental sector of Vietnam, ESS was awarded a contract to provide training in the conduct of isokinetic emissions sampling for employees of the Vietnamese company Environment Analyze and Technique (EATC). EATC selected four of their most-experience and qualified technicians to attend the ESS training seminar, in order to further expand their skills with Apex Instruments isokinetic sampling equipment.

EATC students in Vietnam 2The objective of the three-day seminar was to introduce the EATC technicians to the basic principles of isokinetic testing and develop their sampling skills. The course was designed to train the students to develop the ability to plan, guide, evaluate, and personally conduct the source-sampling techniques and measurements in order to determine certain pollutant’s emission rates from stationary sources. The course provided a detailed review of EPA Methods 1 through 5, used to measure emission rates of Filterable Particulate Matter (FPM) from emissions sources.

Chief among the skills, methods, and techniques provided by the course was an overview of the basic operations of the sampling equipment, including the nomenclature and terminologies associated with its usage. Also covered were the purpose of the relevant testing methods, and an introduction to the field and lab calibrations and calculations that are a part of the methodology. Finally, ESS hosted a field sampling exercise to demonstrate the conduct of a Method 5 test, utilizing the Apex Instruments Source Sampling Train.

Emissions sampling is an increasingly important aspect of environmental protection in the Asian market, as the environmental impact of increasingly-rapid growth and industrialization are felt in the quality of air and water. As ESS’s work has grown in the Southeast Asian region, it has been increasingly important to maintain a staff and local presence in these growing markets. In January of 2013 ESS opened its first Asian office in Hanoi, Vietnam. In early February, ESS signed an agreement with Berkman Systems, allowing ESS to combine its expertise in US EPA sampling methodologies with the Berkman network of operations in Metro Manila, Cebu, and Davao, Philippines. ESS has leveraged its connections to grow rapidly in the region’s environmental sector, and continues to provide cost-effective solutions, and superior technical support for our client’s consulting and air-testing needs.

ESS is proud of our growing list of clients and network with key Vietnamese environmental firms such as EATC. ESS will continue to maintain its competitive advantage by building on its international experience; developing offices in strategic markets and assuring client satisfaction on every project.
