App Notes

Carbohydrates are one of the most important components of foodstuffs and beverages and contribute to taste and nutritional value.

Artificial sweeteners are increasingly used as a low-calorie substitute for sugar in food and beverages and can help to control body weight and insulin levels and aid dental health.

Mycotoxins are secondary metabolites produced by several species of fungi and are considered one of the most important contaminants of agricultural commodities, both in the field and in storage.

A bio-inert flow path is required to manage the complex and reactive sample profiles that are common in today’s fast-paced analytical world.

This application note describes the simultaneous extraction of aldosterone and angiotensin from human plasma using the EVOLUTE® EXPRESS ABN Solid Phase Extraction plates prior to LC-MS/MS analysis.

The practice of bottom-up proteomics relies to a large extent on the separation performance that can be achieved with state-of-the art nano LC-MS/MS equipment.

Characterising petrochemicals by assigning individual analytes to structurally-related groups in a GC×GC workflow has great potential to improve the speed with which petrochemical compositions can be assessed.

Lactose-intolerance is a wide-spread condition, which prevents a large number of people of consuming dairy products. To check the lactose contents in ‘lactose-free’ labelled products a fast, sensitive and selective analytical method is required.

Phenol formaldehyde resins (PFRs) are condensation polymers and are obtained by condensing phenol with formaldehyde in the presence of an acidic or alkaline catalyst.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometers (MALDI-TOF MS) feature simple and rapid detection of low molecular to high molecular weight compounds in a wide range of samples.
