Merlin will qualify each system for detection limits, separation efficiency, method optimization as well as response factors and humidified blank criteria. Guidelines used by Merlin for this qualification are accepted by EPA standards and are provided in our Quality Assurance Plan. A written certification is provided with each system for future reference that outlines all standards used, operational parameters and retention time road maps. Merlin will provide daily standards to be used with the blending system, which are certified and will last the duration of the operating season. Daily standards contain certified concentrations of Propane and Benzene for recovery calculations and up to 12 additional constituents used as reference peaks in the processing methods for the system. Additional EPA 56 component retention time standards and audit samples should be supplied by the customer at the time of installation to be incorporated into the certification document.

System Qualification offers users a comprehensive evaluation of the monitoring system from the onset of its deployment into a field setting. This data can provide operators with concise and detailed documentation by which they can evaluate the system’s subsequent performance. It also provides a standard, which can be used in the event of a system failure to guide operators and maintenance personnel in their efforts to return the system to a similar level of performance.
