Temperature Gradient System Visualizes Compounds in Real Time

Eliminates Sample Preparation Steps

Great for Polymer Analysis Typically Using Gel Permeable Chromatography

The ionRocket visualizes (identifies) the hardly seen compounds in your samples. It generates the heat gradient from the ambient temperature up to 600ºC at the rate of 100ºC per minute. It allows various compounds in your samples to be sublimated or vaporized.

The data obtained from the ionRocket application gives another axis of temperature besides the obtained data from DART®-MS (Direct Analysis in Real Time-Mass Spectrometry). Since the temperature shifts by time in minutes, the given profile shows similar ones to chromatograms. The given data is three dimensional consisting of mass, temperature (=time) and intensity.
