Single analog sensor input
Students learn to work with the gas chromatographer (BT45i) while doing this activity. They use hydrogen gas obtained from the Hofmann apparatus. This activity is easy and fast and helps students to master the BT45i so they can use the gas chromatographer for other more challenging activities. Hydrogen gas gives an easy to analyse chromatogram.
Activity Gas chromatography
In this activity the blood pressure is derived from measurements with the blood pressure sensor. In the analysis the oscillometric method is used.
