Applications and Data Examples

Rapid characterisation of polymers and plastics

Traditionally the analysis of plastics and polymers by mass spectrometry has involved the use of GC-MS or LC-MS. In either technique the whole sample or the surface is required to be dissolved with an appropriate solvent.Using DART or AP-MALDI, these samples can now be analysed intact. As ambient surface ionisation techniques, DART and AP-MALDI can give accurate information about plastics, additives and surface treatments without the need for sample preparation

Detection of migrating products in Food Packaging and Utensils

When a plastic material is used as packaging or when a Utensil is intended for food use, it is important to know whether any compounds are migrating from that plastic into the food and hence entering the food chain. Utensils that are used in high temperature environment can also be a source of phthalates and adipate esters which are regulated compounds in most countries.

In this application note, a variety of plastics used in the food industry were sampled without any preparation using DART with a Linear Ion Trap. See here for the presentation
