A new approach for the analysis of diesel engine fuel filters has been developed. This method involves minimal to no sample preparation, allowing rapid and unbiased analysis of diesel fuel filters. In recent years, diesel fuel filter plugging incidences have increased in parallel with changing emissions legislation. Fuel filter blockages can result in increased emissions, reduced efficiency, and engine failure. It is not fully understood why fuel filter blockages occur; as a result, there has been an international increase in research into the cause of fuel filter plugging. The method discussed in this paper utilizes a thermal desorption (TD) style sample introduction technique that can be used in conjunction with gas chromatography−mass spectrometry (GC-MS) and presents a fast, simple, and more sustainable approach to the analysis of fuel filters. When required, an efficient and straightforward sample cleanup process was developed and was used to simplify and improve confidence in the data identification and assignment; this method is up to three orders of magnitude faster than some procedures adopted in the literature. Further complementary analytical techniques, such as ultrahigh-performance supercritical fluid chromatography−mass spectrometry (UHPSFC-MS) and high-resolution GC-MS, were used to access additional sample-specific information. This new approach has been successful in the identification of problematic materials deposited on blocked fuel filters, concurrent with recent research. This information can aid in the development of mitigation strategies to combat fuel filter plugging.

<div class="section abstract"><div class="htmlview paragraph">There are many anthropogenic climate change mitigation strategies being adopted worldwide. One of these is the adoption of biodiesel FAME (Fatty Acid Methyl Ester), in transportation. The fuel has been widely promoted as replacement for petroleum diesel because of its potential benefits for life cycle greenhouse gas emissions, carbon dioxide reduction and particulate matter improvements.</div><div class="htmlview paragraph">Presently biodiesel may be made from a wide variety of starting materials, including food waste and agricultural materials such as vegetable oils and greases. The number and variety of possible starting materials continues to increase. Though, there is a limiting factor in the use of FAME, and that is cold weather operability. The regional climate can often influence FAME adoption with resultant economic and environmental implications. Often this cold temperature operability manifests itself as in vehicle fuel filter blocking. Several analytical protocols have been produced over the last few years to identify the chemicals in biodiesel that cause this problem.</div><div class="htmlview paragraph">However, the presence of petroleum hydrocarbons compromises many of these methods and others involve derivatization. Here we propose a protocol built around supercritical fluid chromatography mass spectrometry (SFC-MS) and Fourier transform ion cyclotron mass spectrometry (FT-ICR MS) that has the flexibility to meet these challenges and allow the analysis of petroleum diesel/FAME blends and afford detection of the suspect compounds causing filter blocking under cold temperature</div></div>
