Setup for the measurement.

Align the optics.

Document the measurement.

Measure the background.

Add the sample and check the concentration.

Measure the sample.

The perpose of these stages are fully described in chapters 3 and 4 of the Getting
Started manual.

All these stages are automatically controlled by the Qspec MS1 macro. The next
chapter will run through a measurement using the Qspec MS1 macro.
