Comparison of Mass Spectrometry Sample Preparation Methods for Nylon 6,6 Analysis

BioChromato has published a technical note that compares using Evolved Gas Analysis (EGA) and Thermal Desorption (DART®) sample preparation methods for Mass Spectrometry analysis of Nylon 6,6.


Synthesized by polycondensation of hexamethylenediamine and adipic acid – Nylon 6,6 is a polyamide or nylon that is commonly used in the textile and plastic industries. Nylon 6,6 is a polymer of choice when high mechanical strength, rigidity, good stability under heat and/or chemical resistance are required. In this new technical note the authors compare ionRocket-DART®-MS to EGA-MS for analysis of Nylon 6,6 samples.


Evolved Gas Analysis has traditionally been used as a mass spectrometry sample preparation technique for polymers, plastics, and fibres. However, analysis by EGA-MS generates fragment ions and requires a database to confirm the identity of the mass fragments.


By comparison, the authors demonstrate how using ionRocket- DART®/MS you can observe the parent ion without fragment ions because DART® is a soft ionization technique. Consequently, ionRocket- DART®/MS can provide qualitative analysis even if customers cannot find an objective mass fragment within their EGA/MS database.


The ionRocket is a temperature-heating device for direct thermal desorption and pyrolysis of samples, prior to ionization and analysis by mass spectrometry. Using ionRocket a temperature gradient from ambient up to 600ºC can be achieved in just a few minutes. This enables polymers, plastics, and fibres to be pyrolyzed and then introduced into the DART®-MS gas stream.
