App Notes

The ability to isolate and identify differences between commercial beverage samples is made possible using non-targeted Pegasus® GC-TOFMS and ChromaTOF software’s Reference compare tool. This novel approach is an ideal strategy for quality control purposes and building brand awareness.

This application note presents a rapid and inexpensive method for BPA screening in milk samples using a monolithic Chromolith® HighResolution RP-18 endcapped column and fluorescence detection on a Chromaster HPLC system.

The pH value is one of the most important and most frequently measured quantities in analytical chemistry. However, to verify the accuracy of the measured value, the following tips should always be considered before taking a pH measurement.

Overcome misleading library hits of homologous compounds by utilizing superior mass accuracy, CI and EI ionisation features of LECO Pegasus® GC-HRT technology. This high resolution TOFMS approach is ideally suited for the confident identification of unknowns in polymer extracts.

Characterization of food products, including differential analysis, is important in the food industry for quality control, brand awareness, and authentication of materials and products.

As the number of samples for sequencing increases, there is a need for library prep automation that matches the throughput of the next generation sequencing (NGS) instruments while not requiring an investment equal to the sequencer itself.

An SPE protocol for the extraction of a range of mycotoxins from dried chili using ISOLUTE® Myco with LC-MS/MS analysis, achieving high recoveries of relevant mycotoxins with %RSDs and LOQs that meet EU regulations for measurement of these analytes.

Diffusive monitoring is a simple, cost-effective means of large-scale sampling for many air monitoring programs. This poster discusses the background to diffusive sampling, and provides examples of the application of tube-type samplers in real-life applications.

Current extraction and cleanup techniques for fatty samples are time-consuming, expensive, and provide insufficient background removal prior to analysis. For this reason, a new approach was developed.

This application note demonstrates a comparison of gasoline analysis using helium carrier gas following ASTM method D67291 and the use of unfiltered hydrogen carrier gas produced by a Peak Scientific Precision Trace hydrogen generator in DHA following ASTM method D6729 appendix X22.
