“…This usually involve the use of ultra-high resolution mass spectrometry such as FT-ICR of crude oils [124,125]. However, more recently distillates, additives and biofuels are routinely analysed by GC-MS and LC-ESI-MS as well as ADI methods [126,127,128]. Analysis of these fuels and oils provides critical information on the composition and therefore a greater understanding of how the components may interact or degrade over time [129].…”

Development and application of a novel mass spectrometry ionization source for biological chemistry

Since its development, electrospray ionization (ESI) for the analysis of thermally labile, polar compounds and particularly biomolecules has been extremely useful. Not all compounds can be easily protonated and electron ionization (EI) is still a widely used ionization method for compounds like hydrocarbons. However, the low-pressure environment of the EI source requires complex and expensive vacuum systems and inlets. Therefore, a source which can ionises non-polar compounds while operating at atmospheric pressure would be highly advantageous. In this thesis I have undertaken development and characterisation of four prototype atmospheric pressure glow discharge ionization sources for the analysis of compounds not normally amiable to ionization by conventional atmospheric pressure ionization sources. A helium micro-glow discharge source (“Prototype V”) operated using a direct current power supply was studied and its discharge characterised. Its current-voltage relationship increased linearly which is typical of the abnormal glow regime while thermal imaging showed it had a “cold” discharge. Prototype V was successfully interfaced with a Xevo G2-S time-of-ﬂight and a Xevo TQ-S triple quadrupole (Waters Corp, Wilmslow, UK) and used with a range of sample introduction methods, initially a solids probe, but later APCI and ESI probes. These probes enabled prototype V to readily integrate with separation sciences; speciﬁcally liquid chromatography was demonstrated for complex mixture analysis. Prototype V exhibited high analytical sensitivity in the nanogram range in both positive and negative modes and could ionize a wide range of compound chemistries from polar to non-polar. In particular it showed sensitivity to non-polar compounds in negative-ion mode when compared to ESI. This gives the source the potential to operate in conjunction with a range of sample inlets and in combination with other ionization techniques as part of a multimodal platform to analyse the widest range of samples and a step towards a universal source.

“…In general, a dye marker is extracted into an aqueous layer and quantified by UV-visible absorption spectroscopy [44,46,47] and fluorescence spectroscopy [48] techniques. Mass spectrometer has also been studied for this purpose due to it extremely high sensitivity and selectivity [49] but its applications for on-site analysis is limited by the cost and size of the instrument system.…”

This thesis deals with two parts of development of novel sensors based on cellulose substrate platform. The first part is the development of fluorescence sensors and adsorbents for metal ions using bacterial cellulose as the platform. The second part is the development of colorimetric sensors for smartphone detection of oil marker using filter paper as the platform. In the first part, bacterial cellulose (BC) has several advantageous properties over plant cellulose such as high purity, high surface area, high porosity, and high water-holding capacity due to its three-dimensional network of nanofibrils structure, that make BC appealing for applications related to surface capacity. In this work, BC is utilized as a substrate for immobilization of a 2-chloro-N-(quinolin-8-yl)acetamide (QA) via a nucleophilic substitution reaction using K2CO3 as a base. The QA modified BC film exhibit green fluorescence turn-on emission upon addition of Zn2+. The metal ion adsorption study by the ICP-OES analysis showed the adsorption capacity of 38.2 and 56.8 mg/g for Zn2+and Cd2+, respectively. The functionalized BC sheet is thus potentially useful for detection of Zn2+ and retrieving or removal of Zn2+ and Cd2+ from aqueous solution. In the second part, a convenient method for sensitive detection of gasoline marker using a smartphone camera and image processing application are developed. Phenolphthalein (PhP) is used as a colorless dye marker in commercial gasoline. The color was developed by the interaction of PhP with NaOH on filter paper strips and evaluated based on the CMYK color system by ImageJ program. The counter-flowing technique, in which a gasoline sample and NaOH solution are allowed to travel on a filter paper strip from the opposite end, give the naked eye detection concentration of PhP as low as 1 ppm with the LOD of 0.31 ppm using a smartphone camera. The high sensitivity is attributed to the preconcentration derived from accumulation of PhP at the immiscible liquid interface. The counter-flowing method can thus be a new facile analytical technique for enhancing chemical detection sensitivity.
