Cement manufacturers and power plants that are required to comply with the latest U.S. Environmental Protection Agency (EPA) regulations can now rely on enhanced mercury calibrators to speed compliance with the new regulatory requirements of individual facilities.PROD-ThermoScientific-300

The Thermo Scientific High-Level Model 81iH and Low-Level Model 81iL Mercury Calibrators fully integrate with the Thermo Scientific Mercury Freedom System, enhancing the capabilities currently provided in the standard Thermo Scientific Model 81i calibrator. The new models give operators the flexibility to choose multiple sampling ranges, which provide a wider range of mercury outputs.

The High Level Model 81iH calibrator is designed for applications measuring high levels of mercury, intended to help cement manufacturers comply with EPA’s Maximum Achievable Control Technology (MACT) standards. Mercury emissions can vary depending on the operating condition of the equipment in cement kilns, and the High-Level Model 81iH calibrator allows the mercury system to conduct span checks and calibrations across a large dynamic range.

The Low-Level 81iL calibrator measures low levels of mercury and provides added flexibility to help power plants comply with EPA’s Utility Mercury and Air Toxics Standards (MATS). The emission limit for power plants per the MATS rule is close to the lower end of the standard Model 81i range, and the Low-Level Model 81iL calibrator is specifically designed to maximize performance at lower ranges. Facilities must comply with MACT and MATS requirements in 2015.

“Deadlines for MACT and MATS compliance are looming, and many facilities may need to take action immediately,” said Brent LeClaire, product line manager, environmental and process monitoring for Thermo Fisher Scientific. “We enhanced the calibrators for the Mercury Freedom System to enable our customers to prepare quickly and flexibly for the 2015 deadlines.”

The Thermo Scientific High-Level Model 81iH and Low-Level Model 81iL Mercury Calibrators also offer: a vapor generator to allow calibration of the instrument directly, as well as calibration through the extraction probe; Ethernet connectivity to provide efficient remote access for downloading data from the instrument; ability to perform diagnostic calibrations directly to the analyzer and probe; National Institute of Standards and Technology (NIST) traceability; and additional benefits of the iSeries platform, including flexible communications, ease of service and a simplified interface.
