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 materials are difficult to analyse using DART-MS due to the varying volatility of substituents in these complex samples. 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.
