Unfortunately, the prolonged data acquisitions required to achieve an acceptable signal-to-noise ratio (SNR) tend to deteriorate the energy resolution because of spectral drifts due to instrumental instability. We developed a macroscript for a Gatan Digital MicrographTM to control an ENFINA 1000 EEL spectrometer that corrects for energy drifts during data accumulation. The script successfully achieved a core-loss spectrum for a sample having ∼1 at% elemental concentration, and provided a sufficient SNR for chemical state analysis.}, pages = {149--158}, title = {Energy-drift correction of electron energy-loss spectra from prolonged data accumulation of low SNR signals}, volume = {57}, year = {2008} }
