[Case Study] Identification of Unknown Components Using Directly Introduced Probe High-Resolution GCMS
Rapid identification of unknown components using high-resolution GCMS with a direct introduction probe without chromatography.
The detection and identification of compounds of unknown origin is challenging, often involving complex volcanic processes, and it takes time to obtain results. Additionally, high reliability is required for final identification, which necessitates the confirmation of multifaceted information. By measuring the molecular weight of chemical substances with sufficient accuracy, it is possible to determine the elemental composition and identify the chemical structure of the substance using isotope ratios and fragmentation patterns. Using high-resolution GCMS allows for the reliable detection of target components from complex matrices due to its high mass resolution and mass accuracy. This technical document introduces a method for reliably identifying unknown substances almost instantaneously. It connects a direct injection probe to our high-resolution GCMS (Orbitrap GC-MS system) and rapidly identifies compounds using both electron ionization and chemical ionization.
