Overview
Toxicological analysis of body fluids is crucial for identifying acute poisoning, drug abuse, or illegal substance use. These analyses are resource-intensive due to complex sample pretreatment and identification methods. Quick tests like immunological assays provide initial results, while chromatographic methods offer detailed identification and quantitative information.
System Description
The prominence TOX.I.S. system utilizes HPLC hardware with a special column-switching procedure for urine sample pretreatment, including cleaning and rinsing steps to remove proteins and other components. It also supports blood/serum sample analysis after a separate extraction procedure.
Analysis Procedure
Shimadzu HPLC modules are reliable and high-performing, with stepwise system control. Detection and identification are performed using a photodiode-array detector and UV spectra library matching. The system was developed in collaboration with experts from the Institute of Toxicology, Berlin.
Sample Processing
Urine samples undergo centrifugation, internal standard addition, and are placed in an autosampler. They are transferred to an extraction column for protein removal, then to an analytical separation system. Peaks are identified by retention times and library comparison, generating a report with peak information.
Automated Analysis
The system supports automated poison and drug analysis for urine and serum samples, with detailed steps for sample preparation and analysis.
Library and Validation
The UVTOX UV spectral library, developed over 15 years, is essential for identifying toxic substances. The system includes a standard operating procedure for daily validation and performance checks, with an integrated internal standard for retention time correction.
System Features
The prominence TOX.I.S. system is fully automated, uses standard HPLC modules, and offers easy sample pretreatment and flexible systematic toxicological analysis.
