Abstract:
The physiochemical properties of silica monolith make it an ideal base material for drugs extracting, pre-concentrating and separation from biological samples which can interact not only with molecules but also with ions and atoms. However, the fabrication of silica monoliths still has some problems, such as cost, limited capacity and fabrication and modification methodology, which can be time consuming and labour intensive. Structure evolution of silica monolith was studied in microwave and conventionally processed samples over the temperature range from 25 to 70 oC. The samples were produced

Toxicological and forensic applications of analytical chemistry provide both interesting and unique opportunities for analytical chemists to hone their skills and push their abilities. Modern analytical chemistry has afforded researchers the ability to probe into the intricate pathways of biochemical processes by systematic identification and characterization of biologically relevant compounds. Unfortunately, often due to the restrictive specifications of the instrumentation used, it is necessary to remove those compounds from their natural environments such that their structure and at the ver

The goal of this project was to reduce processing time for forensic DNA testing without incurring significant added costs and/or the need for new instrumentation, while still generating high quality profiles.

Generally, toxicology laboratories utilize a screening method, such as immunoassay, for the presumptive identification of drugs of abuse.

A LA-ICP-MS method was developed and compared to k0-INAA for several milk samples as well as a reference sample. Precision of 10% RSD or better and a bias of 10% was achieved for both techniques for most elements with LA-ICP-MS producing lower limits of detection (~ 1 ppm) for Sr. The comparison of LA-ICP-MS to k0-INAA showed overlap of the 95% confidence intervals

Abstract:
Hollow-fibre liquid-phase microextraction (HF-LPME) was introduced in 1999 as a miniaturised version of liquid-liquid extraction (LLE) in order to reduce the consumption of organic solvents and offer an environmentally-friendly approach to extraction procedures. Since then, several studies have been published in the field of forensic and clinical toxicology applying the technique to a broad range of analytes; however more studies are necessary regarding its applicability to bioanalyses. The principle of HF-LPME is the extraction of analytes across a thin supported liquid membrane within the wa

Abstract:
Human scent, or the volatile organic compounds (VOCs) produced by an individual, has been recognized as a biometric measurement because of the distinct variations in both the presence and abundance of these VOCs between individuals. In forensic science, human scent has been used as a form of associative evidence by linking a suspect to a scene/object through the use of human scent discriminating canines. The scent most often collected and used with these specially trained canines is from the hands because a majority of the evidence collected is likely to have been handled by the suspect. Howev
