Salt gradient analysis of monoclonal antibodies using a 3 μm monodisperse SCX column

This poster presents an example of the analysis of all 17 explosives listed in EPA 8330B using atmospheric pressure chemical ionization liquid chromatography mass spectrometry (APCI-LC-MS/MS), which allowed for more sensitive and selective analysis than PDA detection. In addition, MRM analysis provides an extra layer of confirmation based on the unique fragmentation of each compound.

This poster presents a comprehensive, multi-approach data processing method for the analysis of non-targeted PFAS in both positive and negative ionization modes. Results show this three-pronged approach gave comprehensive identifications without excess false positives.

This poster shows the development and validation of a fully automated sample preparation and subsequent LC-MS/MS with trap-and-elute chromatography assay analyzing 25-hydroxyvitamin-D2 and D3. With this automated platform, technicians can significantly reduce their active time in the sample preparation workflow, focusing primarily on sample registration and results review.

EPA Method 1633A is currently the only validated multi-lab method for PFAS detection in leachate. This poster demonstrates the effectiveness of a system to provide robust, stable performance over 154 injections and 37 hours of continuous PFAS analysis, making it ideal for routine monitoring of complex leachate matrices.

With this AEX method a mix of six oligonucleotides can be separated in under two minutes.

New automated workflow enables fast comparison of chromatograms, revealing sample differences and simplifying essential oil quality control.
