The EZReporter Natural Gas Liquids (NGL) Module is designed to perform Natural Gas Liquids extended analysis and reporting for dual detector (TCD+FID) analyses such as those based on the GPA 2186/2286 standards where bridging or allocation calculations are required. The results from these calculations are available for reporting, monitoring, trend plotting, and exporting.
Overview
The EZReporter Natural Gas Liquids (NGL) Module is designed to perform Natural Gas Liquids extended analysis and reporting for dual detector (TCD+FID) analyses such as those based on the GPA 2186/2286 (and related) standards. The results from these calculations are available for reporting, monitoring, trend plotting, and exporting.
The EZReporter 4.0 Natural Gas Liquids Edition also includes a license for the Natural Gas Analysis module.

Extended Fraction Calculation Methods
There are several different methods to calculate extended (Hexanes Plus) analysis results. EZReporter 4.0 supports the following calculation methods:
- Separate: The TCD and FID extended analysis results are each calculated and reported separately. The TCD results, including C6+, are used to generate the total sample results, while the FID results are used to generate the average extended fraction results.
- Hybrid: The FID extended fraction average results are calculated first and are then used as the constants for the TCD C6+ calculations.
- Combined/Bridging: The TCD and FID extended analysis results are combined into a common report with the option of applying “bridge” factors to normalize the relative response from each detector. The C6+ results in the total sample report are derived from the individual combined FID extended component calculated results. The Calibrated Raw Bridging calculation requires both the TCD and FID to be calibrated, and the bridging calculation is performed using the raw/un-normalized component amounts. Uncalibrated FID calculation methods use peak areas and Unversal Relative Response Factors to estimate FID component concentration.

- GPA 2186-22 Bridging (FID Calibrated and Uncalibrated)
- GPA 2286-24 Bridging (FID Uncalibrated)
- Allocation: The individual FID extended component amounts are first adjusted so that the total FID C6+ amount is equal to the total TCD C6+ amount. The C6+ results in the total sample report are then derived from the individual combined FID extended component calculated results. The Calibrated Raw Allocation calculation requires both the TCD and FID to be calibrated, and the allocation calculation is performed using the raw/un-normalized component amounts. Uncalibrated FID calculation methods use peak areas and Unversal Relative Response Factors to estimate FID component concentration.

Standard Component Data Sources
EZReporter 4.0 includes component physical property constants from the following standard data sources that can be used in the NGL calculations:
- GPA 2145-16
- GPA 2145-09
- GPA 2145-03
- GPSA Engineering Data Book
