该方法用于测定UOP Pacol、UOP Define和UOP Olex工艺进料和产品流中的总正构烯烃（TNO）、单个碳数正构烯烃、总正构烷烃（TNP）和单个正构烷烃。样品可以在C9到C18碳数范围内，由轻端（裂解副产物）、正构烷烃、正构烯烃和相关的非正构化合物组成。正常烯烃包括二烯烃（如果存在）。少量非正构烷烃和正构烯烃洗脱，得到总非正构烷烃（TNN）的近似值。 更准确的TNN值可通过UOP方法411单独确定（见注1）。任何化合物的定量下限为0.01质量%。任何碳数基团的定量下限约为0.05质量-%。

This method is for determining total normal olefins (TNO), individual carbon number normal olefins, total normal paraffins (TNP), and individual normal paraffins in the UOP Pacol, UOP Define, and UOP Olex process feed and product streams. Samples can be in the C9to C18carbon number range, consisting of light ends (cracked by-products), normal paraffins, normal olefins, and associated non-normals compounds. Normal olefins include diolefins, if present. Small amounts of non-normals elute with the normal paraffins and normal olefins resulting in an approximate value for the total non-normals (TNN). A more accurate TNN value can be determined separately by UOP Method 411 (see Note 1). The lower limit of quantitation for any compound is 0.01 mass %. The lower limit of quantitation for any carbon number group is approximately 0.05 mass-%.
