Different sample preparation techniques commonly used for the analyses at the Toxicological centre are described below.
Solid Phase Extraction
Micro Solid Phase Extraction
In micro solid phase extraction, a miniaturized solid-phase extraction (SPE) set-up is applied with a 96 well system containing different SPE sorbents for the recovery and concentration of the targeted compounds. Currently, this analytical approach is employed for the analysis of a broad range of psychoactive compounds in influent wastewater and phosphate flame retardants in human urine.
The homogenator/dissociator is a benchtop instrument for the semi-automated dissociation of tissues into single-cell suspensions or thorough homogenates. A single sample or two samples in parallel can be processed. Two types of unique tubes used with the instrument enable the time-saving and easy dissociation or homogenization of tissues in a closed system. Special protocols have been developed for various tissues, including human liver and kidney.
