Example

Example with mass spectrometer data:

from ttlab import MassSpectrometer


# Create a mass spec object
filename = 'path/filename.asc'
MS = MassSpectrometer(filename)

# Check what gases are included in the data
print(MS.gases)

# Plot one of the gases, using matploltlib, returns the axes
ax = MS.plot_gas('Ar')

# Get the ion current and the relative time for the gas, returns np arrays with the data
ion_current_argon = MS.get_ion_current('Ar')
time_relative = MS.get_relative_time('Ar')
