Gas chromatographic method for simulated distillation up to a boiling point of 750°C using temperature‐programmed injection and high temperature fused silica wide‐bore columns

Abstract: It is demonstrated that linear injection characteristics are obtained for a wide boiling point range sample using a temperature‐programmed injector in combination with wide‐bore fused silica columns. The applicability of the described combination for high temperature simulated distillation is described. The method, using external standardization, gives accurate and repeatable results for different types of samples in the boiling range between 50 and 750°C. The lifetime of the fused silica wide‐bore columns was… Show more

“…Existem cinco métodos utilizados para a destilação simulada, que devem ser escolhidos de acordo com o tipo de amostra que será analisada: D-3710, D-5307 e D-2887, reconhecidos pela ASTM 17 , e D-2887 estendido e HT-750 2,[23][24][25] , não reconhecidos pela ASTM, mas bastante utilizados na indústria do petróleo. A Tabela 1 apresenta o tipo de amostra tipicamente analisada por cada mé-todo 26 .…”

“…Com relação à introdução de amostra, os injetores preferencialmente utilizados para as análises por DS são o injetor na coluna a frio 13,22,36 e o injetor por vaporização com temperatura programável 23,24,37,38 , já que os mesmos diminuem significativamente a discriminação, na agulha, de componentes mais pesados, na transferência da amostra da seringa para o cromatógrafo. Entretanto, o injetor com e sem divisão de fluxo já foi empregado em alguns estudos mais específicos 39,[40][41][42] .…”

“…Whilst an extended oil analysis by distillation takes many days and requires a relative large volume of sample, GC analysis can identify components as heavy as C 80 in a matter of hours using only a small fluid sample 58 . Individual peaks in the chromatogram are identified by comparing their retention times inside the column with those on known compounds previously analyzed at the same GC conditions.…”

“…The composition of oil samples can be determined by gas chromatography. Whilst an extended oil analysis by distillation takes many days and requires a relative large volume of sample, GC analysis can identify components as heavy as Go in a matter of hours using only a small fluid sample [30]. Individual peaks in the chromatogram are identified by comparing their retention times inside the column with those on known compounds previously analyzed at the same GC conditions.…”
