BEFORE YOU BEGIN
Clarify these questions before selecting a system.
How should I choose between QQQ and Q-TOF?
For routine quantification of known analytes, consider QQQ first. If your focus is accurate mass, molecular characterization, or discovery research, evaluate Q-TOF. Final selection depends on analytes, methods, and intended use.
What information is needed for an implementation assessment?
Prepare details of target analytes, matrices, limits of quantification, concentration ranges, daily sample volumes, existing methods, and information system requirements. ESSENSE AI can use these to discuss the overall configuration.
