Let's check out the new PASEF TOF thing!

Okay -- I finally did it. A little more than 2 years later, I finally got to a point where I felt guilty about my rambling about the relatively low quality of the first TIMSTOF data that I had access to and took the original post down.

I'll save it for historic purposes, but Bruker has improved or just fixed every problem that I had with the original instrument. The mass accuracy is better, the speed is even faster and there are options for data processing

Also, the post was just kind of crappy. This placeholder is worse.


  1. Hi Ben,

    you are able to adjust the TIMS scan time which determines the number TOF scans within a TIMS duty cycle. Results have shown that 50ms are much more benefical for number of unique precursors compared to higher TIMS duty cycle time.

    Regarding the monoisotopic isolation - Since you have the ion mobility dimension they is a fewer need to isolate monoisotopically that is the major advantage of the technology.


  2. Ben,

    Did you ever get a chance to run the PASEF data?
