| Description |
The IP391195 method using high performance liquid chromatography (HPLC)
with refractive index detection. has been utilized to determine hydrocarbons group type
(saturates, monoaromatics, diaromatics and polyaromatics) in middle distillates. A
modification to this method is proposed involving the use of hydrocarbon group type
concentrates separated using liquid chromatography as standards in place of single
compound and use of area % and response ratio in lieu of area, slope and intercept has
been investigated. The results from the above two approaches are compared with
standard IP391195 as well as with the gas oil of known composition prepared by mixing
hydrocarbon concentrates. The results from above comparison suggested that the data
derived using hydrocarbon group type concentrates was reliable. Appreciable difference
was not observed in data derived using area percent response ratio and area slope
intercept. The former method was suggested for regular use, as repeatability of area
percent was better than the data based on area. The data generated by both the original
and modified procedure for a set of five gas oil samples obtained from different sources
have been compared and a difference of 0.5-6.5% w/w in saturates. 1.0-3.2% wlw in
