First Steps with the Detector

Before You Start

Your normal LC grade solvents usually give good results most of the time. But
experience shows that baseline noise can be higher (lower signal-to-noise
ratio) when impurities are in the solvents.
Flush your solvent delivery system for at least 15 minutes before checking
sensitivity. If your pump has multiple channels, you should also flush the
channels not in use.
