Analysis of Beer Using a High Speed U-HPLC Coupled to a Linear Ion Trap Hybrid Mass Spectrometer

Instrument Type: LCMSMS

We coupled a HRAM instrument to an ultra high pressure LC. The optimized LC method decreased the total analysis time from 130 to 25 minutes. Considerable time and cost savings facilitate routine process monitoring and quality control applications. Reproducible chromatography combined with reliable highly accurate mass measurements on the LTQ Orbitrap enable fast profiling of complex mixtures for their comparison (typing). Also,unknown components of the mixtures can be identified and their chemical structures confidently assigned using the MSn fragmentation capabilities of the LTQ Orbitrap.

Multi-mycotoxin Screening and Quantitation Using UHPLC, High Resolution and Accurate Mass

Instrument Type: LCMS

Mycotoxins are the toxic secondary metabolites produced by many species of microscopic filamentary fungi occurring on field cereals, including barley. There is a trend toward the simplification of sample preparation procedures as much as possible. Full spectral data acquisition techniques are also preferred because of their ease of usage, along with the possibility of retrospective archived data mining. We introduce a multi-mycotoxin method for analysis of 32 mycotoxins in beer based on very simple sample preparation and UHPLC coupled with full spectral Orbitrap MS detection.

Determination of Acrolein and Other Process Contaminants in Beer, Wine, and Potato Chip Matrices by Liquid Chromatography-Single Quadrupole Mass Spectrometry

Instrument Type: LCMSMS

Carbonyl compounds are widely found in food products. Acrolein is the a,ß-unsaturated carbonyl compound also called prop-2-enal or acrylic aldehyde. Acrolein has a high volatility and very high reactivity.1 To evaluate risk assessment, more information on its occurrence needs to be generated. The aim of this study was to develop an in-house validated method for the determination of a wide range of carbonyl compounds to quantify these process contaminants in beer, wine, and potato chips using LC/MS.

Separation and determination of acesulfame K and sucralose in beer using a polar embedded HPLC column with RI detection

Instrument Type: HPLC

The Thermo Scientific Dionex UltiMate 3000 LC system is applied for the separation and determination of acesulfame K and sucralose in beer. The separation was performed on a Thermo Scientific Acclaim Polar Advantage II (PA2) HPLC column. The results obtained for resolution between acesulfame K and sucralose was greater than 5 and tailing factor were less than 2.0 for both compounds.
