Forensic Toxicology Database for LC-MS/MS
The database includes information on drugs of abuse, hypnotics, psychotropics, pesticides, prescription drugs and natural toxins.
Simplified Acquisition and Identification
The Forensic Toxicology Database includes optimized LC-MS/MS data acquisition parameters and a library database to help clinical and forensic researchers build screening and quantitation methods quickly, simplifying method development.
MRM & Spectral Library database contains information on more than 2,500 compounds
The spectral library database is built using two separation conditions (ODS and Biphenyl). Both methods have information on clinical and forensic compounds of interest in routine analysis. The ODS method contains information on 1,250 compounds and the Biphenyl method contains 1,281 compounds. Compound datasheet includes: monoisotopic mass, RT, CAS number, formula and compound class. This package provides Synchronized Survey Scan parameters (MRM parameters, MRM intensity threshold and triggered product ion scan parameters) optimized for screening analysis.
Enhanced identification by merged spectrum
Each certified reference material was acquired with three different collision energies to generate an information-rich merged-CE spectrum which can be used in library matching and compound verification. Matching with a merged-CE spectrum library can be a powerful tool to identify compounds with a library score.

Fully automated forensic screening of dried bloodspots with MRM Spectrum Mode
An increasing amount of prescription and illicit drugs drive clinical laboratories to more cost effective and faster screening methods in workplace drug testing, roadside testing, rehabilitation programs or post-mortem investigations without compromising established false positive or negative detection rates. Therefore, the increasing sample amount with a large panel of analytes needs to be handled in shorter analysis time and with simple sample preparation steps. In this study we present a fully automated dried bloodspot (DBS) extraction procedure coupled to an LC-MS/MS-system for forensic and toxicology screening of drugs and their metabolites. We use a new approach, the MRM Spectrum Mode, by measuring at least 5 MRM-transitions of each compound to generate a high confidence for the identification of the results.
