“…There are polarographic (Hansatech Instruments Ltd, Oroboros Instruments, Strathkelvin Instruments, Yellow Springs Instrument, YSI) and fluorescence systems (Seahorse XF Analyzers) with an integrated data acquisition, visualization and processing tools [8][9][10][11][12][13] to analyze bioenergetics data. Some of the polarographic systems without these integrated features are still popular, valuable, and viable tools [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. In some cases, a flatbed recorder is used [24,26,27], in other cases, data are digitized [14,[28][29][30][31][32][33] and analyzed with commercial software [25].…”
