JEOL MASS SPECTROMETER

JMS-T100LP AccuTOF LC-PLUS 4G

The most widely used ambient ionization technique

» Offers direct analysis in real time

» It has opened up whole new range of applications.

DART was originally designed for JEOL AccuTOF™ time-of-flight mass spectrometer

Available to replace ion source very easily to ESI, APCI and so on.

High resolution and exact mass measurements provide selectivity

High dynamic range makes it easy to analyze mixtures

Exact masses and accurate isotopic abundances permit identification of unknowns

Fast data acquisition for high throughput

Mass-independent abundance response (for small molecules)

Information from TOF Mass Spectra

» Elemental composition: Exact Mass + Isotope Peaks

» Distinguish isomers: Fragmentation

» Material identification: “Fingerprint” pattern

» quantitative analysis: Ion abundance

» Other experiments: H/D exchange, derivatization, etc.
