Acknowledging 25 years

IT HAS BEEN 25 YEARS SINCE WE DEVELOPED THE SILICA CAPILLARY COLUMN GAS CHROMATOGRAPHY THERMAL ENERGY ANALYSER METHOD FOR THE TRACE ANALYSIS OF EXPLOSIVES AND ORGANIC GUNSHOT RESIDUE COMPONENTS IN HEAVILY CONTAMINATED FORENSIC EXTRACTS J Chromatography. 1982-1987


ALSO WE CELEBRATE THE INTRODUCTION BY US OF THE RIGOROUS QUALITY CONTROL PRINCIPLES REQUIRED TO BE USED WITH SUCH A SENSITIVE SYSTEM, NOW DUPLICATED IN FORENSIC LABORATORIES WORLDWIDE


Researched in the period 1990  Acknowledged in J. Forensic Science.1996


25 years service

FOR 25 YEARS THIS UNMODIFIED METHOD HAS BEEN THE EYES AND EARS OF THE WORLD FORENSIC COMMUNITY IN REGARD OF TRACE EXPLOSIVES DETECTION.

ALSO WE INTRODUCED THE FIRST PICOGRAM METHOD FOR THE TRACE ANALYSIS OF BENZODIAZEPINE DATE RAPE DRUGS USING SILICA CAPILLARY COLUMN TECHNOLOGY.

Latest pioneering research

IN 2007 WE PIONEERED A SYSTEM DURING THE TRIAL OF THE LEEDS INSULIN SERIAL KILLER

(NEWCASTLE CROWN COURT). A VERY HIGH RESPONSE WAS FOUND IN AN INSULIN IMMUNOASSAY PROCEDURE APPLIED TO THE BLOOD OF A VICTIM, HOWEVER THIS COULD HAVE ARISEN AS A RESULT OF AN ACCIDENTAL CROSS REACTIVITY WITH ANOTHER MACROMOLECULAR BIOCHEMICAL MATERIAL UNRELATED IN STRUCTURE TO INSULIN.

THE CASE WAS STYMIED!

USING NANOBORE LC ELECTROSPRAY Q-TOF MS-MS WE SUCCEEDED IN DETECTING AND OBTAINING A PARENT ION PROFILE OF A LOW NANOGRAM TRACE OF INSULIN IN A 4.5 YEAR OLD MINUTE BLOOD SAMPLE (A RESIDUAL SMEAR ON A SAMPLE TUBE)


A FIRST IN UK CASEWORK AND IN THE WORLD AT THAT SENSITIVITY!!

WE CURRENTLY ARE ENGAGED IN A RESEARCH PROJECT ATTEMPTING TO DEVELOP A RELIABLE METHOD FOR THE DETECTION OF TRACES OF NITROCELLULOSE IN GUNSHOT RESIDUE SAMPLES.

A DIFFICULT CHALLENGE!
