Ambient Ionisation Mass Spectrometry For The Characterisation Of Polymers And Polymer Additives: A Review, Martin R. L Paine, Philip J. Barker, Stephen J. Blanksby
Ambient Ionisation Mass Spectrometry For The Characterisation Of Polymers And Polymer Additives: A Review, Martin R. L Paine, Philip J. Barker, Stephen J. Blanksby
Faculty of Science, Medicine and Health - Papers: part A
The purpose of this review is to showcase the present capabilities of ambient sampling and ionisation technologies for the analysis of polymers and polymer additives by mass spectrometry (MS) while simultaneously highlighting their advantages and limitations in a critical fashion. To qualify as an ambient ionisation technique, the method must be able to probe the surface of solid or liquid samples while operating in an open environment, allowing a variety of sample sizes, shapes, and substrate materials to be analysed. The main sections of this review will be guided by the underlying principle governing the desorption/extraction step of the analysis; …
Paint Spray Mass Spectrometry For The Detection Of Additives From Polymers On Conducting Surfaces, Martin R.L Paine, Philip J. Barker, Stephen J. Blanksby
Paint Spray Mass Spectrometry For The Detection Of Additives From Polymers On Conducting Surfaces, Martin R.L Paine, Philip J. Barker, Stephen J. Blanksby

Paint Spray is developed as a direct sampling ionisation method for mass spectrometric analysis of additives in polymer-based surface coatings. The technique simply involves applying an external high voltage (5 kV) to the wetted sample placed in front of the mass spectrometer inlet and represents a much simpler ionisation technique compared to those currently available. The capabilities of Paint Spray are demonstrated herein with the detection of four commercially available hindered amine light stabilisers; TINUVIN® 770, TINUVIN® 292, TINUVIN® 123 and TINUVIN® 152 directly from thermoset polyester-based coil coatings. Paint Spray requires no sample preparation or pre-treatment and combined with …

A national telephone survey of a representative sample of 1200 Australian adults was conducted in March 2002 in order to identify the factors of greatest concern to consumers in relation to the safety and quality of food, to measure recent trends in views about hazards in the food supply, to explore beliefs about the safety of additives and to discover whether consumers use food labels to check for ingredients of concern. Forty five percent of Australians responded that they were more concerned about the safety and quality of food than they were five years previously, while only 5% were less …
