Comparison of Medipix counting mode (a)–(c) and time-over-threshold mode (d)–(f) of the Timepix detector using the total ion image (a) and (d) and the selected ion images of copper (b) and (e), and the organic dye (c) and (f).
Line scans from the copper signal of a TEM grid used to calculate the spatial resolving power. Acquired with the Timepix detector (a) and the original MCP and TDC detector system (b).
Mass spectrum of PEG mixture measured with the Timepix detector (a) and with the MCP-TDC (b). The sodiated ions of different length PEG oligomers are marked (*). Insets show a selected peak at m/z 437 ([PEG9+Na]+ ion).
Time-resolved overlay image of the green organic dye standard below a TEM grid. The plotted masses are m/z = 63 (copper grid, a), m/z = 385 (organic dye, b), and the overlay of the two images (c).
Overlay of different time resolved images of a mouse testis section. The selected ion images are m/z 115 (indium, red), m/z 369 (cholesterol-OH, green), and m/z 358 (blue).
