Simdist
Reporter for EZChrom.
Support for all ASTM, CEN, DIN, IP and ISO standard methods: ASTM D7096, D6417, D5307, D7213, D2887, D6352, D3710, D7500 ISO 3924 IP 406, 480 type A, B and C, 507, 545 DIN 51435, 51.581-2003 (Noack) EN 15199-1,2,3 Besides
the boiling point distribution report , a quality control report is available
as well. This report shows the conformity with reference samples, and
is therefore very important for the overall reliability of the method.
See table 3: 'LIM' shows the allowed deviation, while 'DIF' is the actual
difference.
Simdist reporter provides several correlations such as :

HIGH SPEED SIMDIST analysis in under 4 mins Simulated distillation (Simdist) is a GC method, used to characterize petroleum products, fractions, lube oil and crude oil. Simdist determines the boiling range distribution in a quick, automated and reliable way. This method replaces the laborative and dangerous D86/1106 methods. True boiling point (TBP) data is vital information for improving refinery profit margins.
Samples are analysed on a non polar column, separating hydrocarbons in order of their boiling points. These are correlated with the retention times from a range of n-alkanes eluting under exact the same conditions and in the range of the sample. A blank analysis is subtracted from the sample chromatogram in order to correct for column bleeding. It is of great interest that the GC instrument has a very good run to run reproducibility. Results are reported as a correlation between the boiling points and the percentages of the sample eluted from the column. The results are confirmed by running a well known standard sample as external standard. The Simdist data correlates with ASTM D86 or D1160. The determination of boiling point distribution of petroleum products and crude oils by conventional GC is a rapid and reliable tool, which is widely used to replace conventional distillation methods. This proven technology is supported by several standard methods.. The
analysis time of conventional Simdist analysers is 30-60 minutes, while our High Speed analyser delivers the results in only a couple of minutes! |
