Sample Heating Device

BioChromato Inc.Request Info

The ionRocket from BioChromato Inc. is a temperature-heating device for direct thermal desorption and pyrolysis of samples prior to ionization and analysis by mass spectrometry.

The system gradually heats a sample placed directly beneath the DART-MS gas stream. Gradient heating of the sample before ionization creates time-/temperature-resolved mass spectra, separating species both by their thermal desorption profiles and mass to charge ratio. It generates a temperature gradient from ambient up to as high as 600 °C in a few minutes. Sample compounds can be sublimated, vaporized, or pyrolyzed, according to their volatility, then introduced into the DART-MS gas stream. Because the ionRocket offers the option to weigh samples prior to analysis, this results in reproducible mass spectrum intensity, allowing calibration curves of analyte amount versus peak intensity to be calculated.

The data produced resembles that of an LC-MS or GC-MS chromatogram, consisting of temperature/time, m/z, and intensity. This can separate rare from abundant species, making them easier to detect.
