The 30mx 0.25mm ID columnwas unable to
adequately resolveTBA fromMTBE.
Extracted ion chromatograms illustrate that a
minor ionofMTBE (59) contributed to the area
ofTBA.. The optimizedoven conditionswere as
follows: 35°C (hold 6min.) to 90°C@ 8°C/min.
(hold 1min.) to 220°C@ 16°C/min. (hold 2
min.). TheGC runtimewas 24minuteswitha
cycle time of 30minutes. SinceTBA is a
breakdown component ofMTBE these column
dimensions and conditions arenot
recommended for the analysis ofTBA.
