ChroZen ASTM D4815 Player
ChroZen ASTM D4815 Player can analyze oxygenates in the form of ethers and alcohols in gasoline and meet regulatory requirements according to ASTM D4815.
Alcohols and ethers in gasoline
were analyzed by ChroZen GC/FID with column switching valve and two types of
column were used; micro-packed TCEP as a pre-column and PDMS
(Dimethylpolysiloxane) non-polar column according to ASTM D4815.
Summary of Test Method
As shown in the result below, all kinds of oxygenates such as MTBE, TAME, DIPE, ETBE and the C1-C4 alcohols are separated clearly. The repeatability in 10 sequence injections satisfies with the regulation indicated in ASTM D4815.
Analysis of Oxygenate Mixture
Specification :
The analysis of oxygenates in gasoline by ChroZen GC with 10 port switching valve guarantees great repeatability and linearity by satisfying the specification of ASTM D4815. The correlation coefficients of calibration curve for all compounds in the calibration standards were determined to greater than 0.999 and the mass % of all components were under 0.1 mass %. Therefore, the ChroZen GC is the optimized system to analyze oxygenates in gasoline with the superior data reliability.

Abstruct
Octane number is a measure of the knock resistance of gasoline.
The higher the octane number, the lower knock resistance.
Therefore, the gasoline with high octane number is marketed as a
premium gasoline. Generally, 8-15% of fuel additives in the form of
alcohol or ether are added to gasoline to increase the octane
number.
Not like other additives such as olefins that can generate toxic
pollutant like formaldehyde and acetaldehyde, oxygenates help
fuel to burn more efficiently and reduce emission of air pollutants.
Generally, alcohols and ethers such as methyl tert-butylether
(MTBE), ethyl tert-butylether (ETBE) and ethanol are used for
oxygenates. Among those oxygenates, most commonly used
methyl tert-butylether (MTBE) produces nitrogen oxides and
aldehydes causing air pollution, it is required to be regulated by
ASTM D4815 to determine % concentrations.
In this study, ethers, alcohols and other oxygenates in gasoline
were analyzed by ChroZen GC with 10-port switching valve
referring to ASTM D4815.
