Webinar Date/Time: Thursday, March 16th, 2023 at 8am PST | 11am EST | 4pm GMT | 5pm CET
This webcast will present a logical approach to identifying whether a problem has been caused by the sample/method or the instrumentation itself, followed by identifying which instrument component may be at the root of the issue. We will share tips and trick to help you identify the most common problems and how to properly set up your method and instrument.
LC-MS is a complex technique which makes troubleshooting that little bit more challenging. We will take you through a step-by-step approach which can be used to determine if the problem is related to the method/sample or if it is an instrument fault—and then how to further narrow the source of the issue to particular LC or MS components. Common problems such as contamination, misidentification of the molecular ion, poor signal reproducibility, and ion suppression will also be discussed.
