Sift-Ms: Development of Instrumentation and Applications SIFT-MS: DEVELOPMENT OF INSTRUMENTATION AND APPLICATIONS Gregory James Francis Department of Chemistry A thesis presented for the Degree of Doctor of Philosophy at the University of Canterbury, Christchurch, New Zealand. December 2007 “I decorated it myself. Thank you, you’re too much. Honestly, it was nothing.” -Keith Buckley Dedicated to Esmé Margaret Colville who sadly passed away while this thesis was in preparation. A generous, wise and loving grandmother who was guiding light in my life and proved that the world through an artists eyes is a beautiful place.

In early 2003, Murray was gracious enough to accept me into his research group as a BSc(Hons) student, even though I had recently neglected to hand-in an undergraduate assignment he had set. To this day I am still reminded about that assignment on a regular occasion! Murray's wisdom and sharp wit have helped me resolve many issues during the course of this research and made the process very enjoyable; to him I am forever indebted. Furthermore, many thanks to my assistant supervisors Dr. Daniel Milligan, Dr. Barry Prince, Dr. Vaughan Langford and Dr. Paul Wilson. Each has had a large role in the day-to-day supervision of the research presented herein and without their expert input, many research avenues would not have been pursued or explored to their full potential. Gratitude is extended to the employees of Syft Technologies, where the majority of the research presented herein was undertaken. I could not ask for a more pleasant group of people to spend 40-50 hours per week (and sometimes a few hours in the weekend) with. All of the 61 employees who I have encountered in the previous three and a half years have had some part to play in this thesis and for that I am very thankful. Particular gratitude is reserved for CEO Geoff Peck, who has provided me many tremendous opportunities that few Ph.D. students even dream of, let alone accomplish. Because of Syft Technologies and Geoff, I have learned to see science from both an academic and commercial point-of-view, as well as being able to travel the world. I also wish to thank staff and students at the University of Canterbury Chemistry Department. Particular thanks go to Dr. Robert Maclagan for advice on computational studies, Dr. Colin Freeman for general advice on gas-phase ion-molecule chemistry and Robert McGregor for blowing the glassware discussed herein (and then repairing that glassware when I had broken it). Also thanks are given to the University of Canterbury based SIFT group, Sam Edwards and Dr. Brett Davis, for allowing me to share laboratory and office space, and a few good laughs. I wish to acknowledge the researchers involved in the chemical warfare program at the Defence Science and Technology Organisation in Melbourne, Australia for their time and involvement in work presented herein. - vi - Special thanks go to Prof. Diethard Bohme for welcoming me into his research group at York University (Toronto, ON, Canada) in 2003 and for his guidance and support during the six months I spent in Toronto as a research assistant. I would also like to extent thanks to the remainder of the Bohme group

  • Critical Care Management of Chemical Exposures 4 the Patients Were Decontaminated Prior to Arriving at the Hospital
    Chapter 4: CRITI C AL CARE MANAGE M ENT OF CHE M I C AL EXPOSURES James Geiling, MD, FCCM Vincent M. Nicolais, MD, FCCM Gregory M. Susla, PharmD, FCCM The views expressed in this article are those of the authors and do not necessarily reflect the position or policy of the Department of Veterans Affairs. Objectives ■ Review measures of preparedness and planning. ■ Describe the purpose of decontamination. ■ Discuss how to evaluate whether a patient has been adequately decontaminated to enter the emergency department (ED), hospital, or intensive care unit (ICU). ■ Summarize the steps necessary to protect hospital staff: decontamination, personal protective equipment (PPE). ■ Review specific agents: diagnosis, identification, and management. If supposedly civilized nations confined their warfare to attacks on the enemy’s troops, the matter of defense against warfare chemicals would be purely a military problem, and therefore beyond the scope of this study. But such is far from the case. In these days of total warfare, the civilians, including women and children, are subject to attack at all times. Colonel Edgar Erskine Hume, Victories of Army Medicine, 1943 Fundamental Disaster Management Case Study A young couple was transported to your hospital’s ED from a local cinema. You have been told there are many others who are being cared for by the emergency medical services and are en route. The 18-year-old male and 17-year-old female were admitted to your ICU after intubation and placement on mechanical ventilation. They are unresponsive and diaphoretic, and they have constricted pupils with excessive lacrimation, vomiting, diarrhea, and restlessness.

This information is distributed solely for the purpose of pre dissemination public comment under applicable information quality guidelines. It has not been formally disseminated by the Agency for Toxic Substances and Disease Registry. It does not represent and should not be construed to represent any agency determination or policy. ***DRAFT FOR PUBLIC COMMENT*** ACETONE iii FOREWORD This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The focus of the profiles is on health and toxicologic information; therefore, each toxicological profile begins with a relevance to public health discussion which would allow a public health professional to make a real-time determination of whether the presence of a particular substance in the environment poses a potential threat to human health.

Gripped by this fear, countries around the world have continued to research, develop, and test these weapons in the spirit of mutually assured destruction.

Nerve agent sarin [2-(fluoro-methyl-phosphoryl) oxypropane] is an organophosphate (OP) compound that is recognized as one of the most toxic chemical warfare agents. Considering sarin’s high toxicity, being odorless and colorless, dimethyl methylphosphonate (DMMP) is widely used as its simulant in the laboratory because of its similar chemical structure and much lower toxicity. Thus, this review serves to introduce the development of a variety of fabricated chemical sensors as potential sensing materials for the detection of DMMP in recent years. Furthermore, the research and application of carbon nanotubes in DMMP polymer sensors, their sensitivity and limitation are highlighted. For sorption-based sensors, active materials play crucial roles in improving the integral performances of sensors. The novel active materials providing hydrogen-bonds between the polymers and carbon nanotubes are the main focus in this review. Keywords: carbon nanotubes, DMMP, chemical sensor, conductive polymer.
