Increasing Speed of UHPLC-MS Analysis Using Single-stage Orbitrap Mass Spectrometer

Instrument Type: LCMS

Productivity of an LC-MS system is measured in samples per day. Modern ultrahigh pressure LC-MS (UHPLC-MS) methods increasingly deal with very short gradients, leading to chromatographic signals with peak widths below 5 seconds at the base. It is still a challenge for high-resolution, accurate mass (HR/AM) systems to provide a sufficient number of scans (=10) across the chromatographic peak in full scan mode without compromising sensitivity and selectivity. We describe a system that addresses these challenges.

Quantitative and Semi-Quantitative Determination of PPCPs and Their By-Products in Wastewater by Orbitrap MS

Instrument Type: LCMS

Pharmaceuticals and personal care products (PPCPs) and endocrine disrupting chemicals (EDCs) detected in surface and drinking waters, as well as in treated wastewater. They are an issue of increasing international attention due to potential environmental impacts. We developed an analytical method capable of determining PPCPs and their by-products in wastewater treatment plant (WWTP) samples. This workflow was applied in a survey of 35 permeate samples obtained from a pilot anaerobic membrane bioreactor (AnMBR).
