Toxtyper™ – a Comprehensive LC-MSn Screening Solution for Clinical and Forensic Toxicology

In the clinic and the routine lab, fast and unambiguous identification of toxic compounds is the primary task. The screening solution presented here is based on ultrahigh performance liquid chromatography (UHPLC) coupled to an LC-MSn ion trap system.
App Note / Case Study

Automation of Solid Phase Extraction (SPE) Multi-method for GC/MS Analysis of Drugs of Abuse in Human Serum

This application demonstrates the extraordinary flexibility of the GX-271 ASPEC and TRILUTION LH software since the desired SPE products can be eluted in fractionated mode.

Enhanced method development capabilities with automated SPME extraction optimization

A workflow has been described enabling the automated selection of the most suitable extraction conditions (type of fiber, extraction time and temperature) for the GC/MS analysis of a number of contaminants in oil and water samples.
Applying the automated workflow described above the total time to identify the most suitable fiber and then optimize conditions was 4.5 days. Compared to performing the experiments manually which is estimated at 15 days this represents of time saving of 10 days.

Detection and Identification of Dispersants (COREXIT® 9527 and 9500) by GC/MS and LC-MS/MS

Dispersants are plasticizers commonly used to prevent clumping and help dissipate oil slicks. In this work, we used GC/MS and LC-MS/ MS to detect and indentify two of the most widely used dispersants (Corexit 9527 and 9500).

Detection of Environmental Contaminants Caused by the Oil Spill in the Gulf of Mexico by GC and HPLC

In order to help understand the impact that the oil spill has caused, laboratories are looking for rapid and robust analytical procedures to characterize the hydrocarbon contaminants. This work provides SPE, GPC, GC-FID, GC/MS, and HPLC analytical methods for analyzing the most common contaminants that originated from the leak.

AN INTEGRATED 1H NMR, GC-MS AND HPLC-(ESI/TOF) BASED METABOLOMICS APPROACH TO THE STUDY OF ACUTE EXERCISE IN HUMAN SERUM METABOLOME

There is an increasing concern about the different response and effect that acute exercise induces on diabetic people and a novel insight into this effect can be performed using a metabolomic approach. Metabolomic is becoming widely spread used as a new and powerful tool for discerning significant changes at metabolic level. In this study we aimed to perform a non-targeted analysis and to identify metabolic differences arisen after 30 minutes of acute exercise in both young men suffering from Ty

Temporal Dynamics of Pathogenesis Related Metabolites and their Metabolic Pathways Following Inoculation of Potato Leaves with Phytophthora infestans

The resistance in potato cultivars against late blight caused by Phytophthora infestans is classified into vertical and horizontal. Several metabolites associated with resistance have been detected: phytoalexins such as rishitin, phytuberin, lubimin, solavetivone etc. Metabolite profiling is a novel technology for the discrimination of quantitative resistance in plants against pathogen stress.
