scope:

This analytical method is applicable for liquid hydrocarbon mixtures which may contain components of N, CO₂, and/or hydrocarbon compounds C₁ - C₁₄ which fall within the ranges listed in Table 5.1. This method is performance based, so any GC system may be used if it meets or exceeds acceptance criteria using the GPA 2186 precision table data in Section 9 to evaluate performance.

NOTE 5.1 - The round-robin data used to produce the precision tables for this standard includes a sample containing 62 mole percent of C₆ plus with a molecular weight of 93, therefore it is recommended that the analysis of samples containing a higher molecular weight C₆ plus be made in accordance with GPA 2103.
