A PROBABLE WORLD FIRST SUCCESSFUL ENDOGENOUS ALCOHOL CHALLENGE (27/10/11)

Defendant acquitted of a charge of aggravated drunken driving, on the grounds that a part of the alcohol detected in his system may possibly have been generated endogenously as a result of severe gastrointestinal challenge

CASEWORK

1: First casework and likely known application of nanobore UHPLC electrospray Q-TOF MS-MS to the detection and identification of nanogram traces of human Insulin in a 4.5 year old blood sample (R v Campbell Norris).

2: First proof of the possession of 1 Kilogram of high THC cannabis as being likely to have been for the purpose of a defendants own personal use (R v Tang).

3: First demonstration (as a result of multi disciplinary expertise) that police transports and stations were likely to be contaminated with gunshot residue as a result of police seized weapons and police officers and suspects who had recently discharged weapons.

4: In R v Crawford (2011) (Gunshot Residue) our observations of the likely common usage of very large numbers of cartridge operated bolt guns and staple fasteners having primer activation and also very often nitroglycerine as a propellant energetic additive in construction, appears to have been recognised by the implementation in forensic laboratories of new precautionary briefings to those visiting, that they should have showered and changed their clothes before coming to the laboratory if they have recently used such devices.

TRACE ANALYSIS

1: First method for GC analysis of explosives using silica capillary column GC.

2: The GC/TEA selective method of choice for the routine detection of explosives and organic firearms discharge residue components in heavily contaminated forensic extracts, and application in casework (Lockerbie: metal fragments from the luggage container, Hyde Park bombing: discarded attache case from the bomb, and also gunshot residue on the window sills of the Libyan Embassy in London).

3: The first method for the TLC characterisation of Nitrocellullose. (Under further development).

4: The first capillary GC method for the analysis of benzodiazepine date rape drugs.

5: The first capillary GC method for the analysis of prostaglandin markers (present in semen) in rape cases.

6: The first application of clean room technology and routine trace analysis of surfaces within the laboratory to the forensic detection of ultra low levels of explosives.

7: The first application of capillary SFC/TEA to the trace analysis of explosives (especially highly involatile explosives such as HNBB) and also benzodiazepines.

8: Novel headspace and solid phase methods for cleaning up highly contaminated samples for the forensic trace analysis of drugs and explosives.

CHEMICAL SYNTHESIS

1: Novel applications in pyrrole chemistry (research ongoing).

2: Novel synthetic approaches to the barbiturates using carbodiimides and alkali metal liquid ammonia and high pressure catalytic hydrogenolysis.

3: Novel chemical approaches to the bicyclic and tricyclic bornanes.

4: Novel attempts at approaches to Cyanoacrylate chemistry in relation to fingerprinting.
