The timsTOF fleX is a high performance UHR-OTOF system with integrated dual ESI/MALDI source, exhibiting high speed and robust MALDI Imaging for all imaginable X-Omics analyses. The additional trapped ion mobility feature adds another separation dimension to unravel complex data and make annotations in MALDI Images more reliable through CCS-matching. Since ASMS 2020 we switched to the next level to gain higher sensitivity for a broad range of compounds and equipped the instrument with a second laser allowing for postionization (MALDI-2).
MALDI-2 uses laser based postionization to enhance and enrich the MALDI experiment, providing access to chemical classes typically opaque to MALDI, at unprecedented sensitivity (2-3 orders of magnitude compared to traditional MALDI) Postionization significantly boosts ion yields for many different analytes and reduces the ever-challenging ion suppression effects in MALDI imaging.
The peer-reviewed and in-peer-reviewing communications listed below is a non-exhaustive list from the work initiated on the first timsTOF fleX (MALDI-2) instruments in the field in the years 2019-2021 and many more are to come.
