![]() ![]() DART can also be used in the analysis of synthetic polymers and plastics. It is very quick and requires little to no sample preparation. DART BasicsĭART is an open-to-atmosphere, surface-desorption ionization method that works for most of small to medium sized organic and organometallic analytes. Mass spec should NOT be used to measure purity, except in special cases. confirming or identifying isotopic labelling or kinetic isotope effects.confirming or proposing elemental composition.confirming the presence of elements with stable isotopes.It is also insufficient to state that you “did mass spec” on a sample you need to be specific in terms on ionization and detection to convey useful information. Because of this, you need to carefully consider the chemical and physical properties of your analyte, as well as published precedents, before selecting a particular ion source and mass spectrometer for analysis. The physics are different, the applications are different, and analytes do NOT behave the same way, sometimes in strange and unpredictable ways. Mass spectrometry (MS), on the other hand, is an umbrella term that describes a multitude of approaches to measuring a physical property (voltage, time, frequency, etc.) that is proportional to the mass-to-charge ratio of the analyte. All NMR spectrometers operate on the same fundamental physical principles, and all analytes behave in predictably similar ways. It will not work for very polar molecules, like sugars and peptides. DART is an open-to-atmosphere, surface-desorption ionization method that works for small to medium sized organic and organometallic analytes. The Eaxctive is a high-resolution, accurate-mass capable instrument, so you can use it to confirm or propose elemental compositions. The “DART” spectrometer is an Exactive Orbitrap mass spectrometer equipped with a Direct Analysis in Real Time (DART) ion source. If you seem to know what you are talking about, I will walk you through running your sample at the instrument and you will be cleared to use the DART on your own.
