Techniques developed


1: The GC TEA method for the screening of highly contaminated real world
  samples for traces of explosives.
2: The quality control techniques used for the operation of Laboratories involved in
  the trace analysis of explosives and other forensic chemicals of interest (eg DNA)
  at the low nanogram level.
3: The silica capillary column gas chromatography method for detecting low
  nanogram traces of date rape benzodiazepine drugs in small (100 microlitre blood
4: The prostaglandin method for investigating sexual offences.
5: The GC/TEA method for detecting traces of Organic Components of gunshot
6: Vacuuming, headspace, and absorbent clean-up techniques for the trace analysis
  of explosives, gunshot residue, prostaglandins, and drugs in heavily contaminated
7: First use of Nanobore HPLC Electrospray MS (Quadrupole)/MS(Time of Flight) to
  detect and identify nanogram traces of Insulin in a casework sample in the UK.
  (R v Campbell Norris).
8: The TLC technique for the trace analysis and differentiation of different types
  of Nitrocellulose.
9: Highly specific TLC method for the detection and identification of low nanogram
  levels of nitroaromatic explosives in highly contaminated samples using laser
  induced fluorescence.
10: A general HPLC method for the analysis of Acid/Neutral drugs using UV detection
11: Selective Analysis of Sulphur compounds in food extracts (alcoholic drinks).
12: Analysis of water for traces of a pesticide widely used in Denmark (unpublished).
13: Manual of Improved improvised Incendiary and Explosive Devices.
14: Development of Improved syntheses of Barbiturates for use in the preparation of
  Radioactively labelled compounds for use in the investigation of the permeability
  of the cell membrane.
15: A method for the low level trace analysis of thyroxine in small blood samples
