Example data (and solution)

The Challenge

The example challenge data was measured on a Bruker micrOTOF-Q, with an expected <5ppm mass accuracy and 12000 resolution during routine measurements. The files were truncated around the retention time 319.5 sec, where the [M+H]+ of the unknown compound elutes during a 20 minute gradient on a Waters Acquity UPLC with acetonitrile/water. Another compound elutes at 323 sec.
