Xiaohong has more than 20 years of experience in the area of inorganic chemistry, with a range of skills in the analysis of water, soil and biological samples, by means of atomic absorption spectrophotometer (AAS), Inductively Coupled Plasma spectrometry (ICP-OES, ICP-MS), High Performance Liquid Chromatography (HPLC) and Flow-Injection Analysis (FIA). She is experienced in routine metal and nutrients analysis , and has the research capability to improve existing methods and develop new analytical protocols through research investigation.
She has completed a research project of method development for As and Hg speciation in water, urine and seafood samples by HPLC-ICPMS. These two methods have gained NATA accreditation in May 2012. As a result of this research project, Forensic and Scientific Services has become the first provider of NATA-accredited services of As and Hg speciation analysis of water, clinical and food samples in Queensland.
Xiaohong has completed a Chromium (Cr) speciation research project and a new method of Chromium speciation has been developed which enhances FSS service capacities and improves public service about water quality management.
Xiaohong is a participant in two research projects to develop speciation methods of selenium (Se) and Cyanide in water and food samples. The outcome of these projects will improve the comprehensiveness of water testing for potability and discharging compliance.
Xiaohong is currently in charge of Arsenic and Mercury speciation and metal analysis in inorganic chemistry group at Forensic and Scientific Services.
