Rapid, accurate determination of ethers, alcohols, aldehydes and ketones, present in many hydrocarbon process streams, is a recurring challenge. Even the residual traces of these compounds can inactivate costly, high-yield catalysts commonly used for large-scale polymer production. Unfortunately, todays standard gas chromatography (GC) methods for oxygenate analysis are not suitable for ever decreasing detection limits. While low-ppb oxygenate concentrations can be detected using lab-based gas chromatography-mass spectrometry (GC-MS) instruments, these systems have seen limited deployment due to their size, complexity of design and specialist maintenance required for continuous operation.View Resources
The G908 oxygenate analyzer integrates the speed and separating power of ballistic gas chromatography with ultra-compact, low maintenance and rugged high pressure mass spectrometer (HPMS). G908 quantifies oxygenates at low-ppb levels in under 5-minutes using selective ion monitoring (SIM). This significantly increases both selectivity and sensitivity relative to standard GC flame ionization detection.
