Mar 16 2021 Read 318 Times The ionRocket from BioChromato Inc is a temperature-heating device for direct thermal desorption and pyrolysis of samples, prior to ionisation and analysis by mass spectrometry. Direct Analysis in Real Time Mass Spectrometry (DART-MS) is a proven technique that enables rapid analysis of both solid and liquid samples under standard laboratory conditions without sample preparation. However, certain polymers, cosmetic powders and forensic materials are difficult to analyse using DART-MS due to the varying volatility of substituents in these complex samples. Even insoluble samples can be measured using the ionRocket/DART-MS set-up without treatment. To overcome these challenges, BioChromato developed an innovative sample introduction device (ionRocket), which gradually heats a sample placed directly beneath the DART-MS gas stream. Gradient heating of the sample before ionisation creates time/temperature resolved mass spectra, separating species both by their thermal desorption profiles and mass to charge ratio (m/z).
