A109. If the FID or IR monitor measures total hydrocarbons, an annual non-methane organic carbon correction factor must be established, per section 98.344(b)(6)(ii). Some infrared monitors operate in such a manner as to detect only methane; these “methane-specific” analyzer systems do not need to establish or use a correction factor.
