“…An elliptical flight path composed of four toroidal electric sectors works with a new segmentation method to identify the number of laps transited by ions of a given m/z. 22 The most recent multipass designs include doughnut-shaped ion optics, 23 a spiral path electric reflector 24 and multiple angle reflecting electrostatic ion mirrors 25 (Figure 1, middle). The latter two designs have achieved broadband mass resolving power of 60 000.…”

“…In the last 15 years, multi-turn and multipass instruments have reported mass resolution in the high tens-of-thousands, approaching the lower end of resolution for Fourier-transform systems [7][8][9][10][11][12]. Yet, single-reflectron TOFMS instruments are the most common because they are useful for the study of transient events such as are produced by laser ablation [13][14][15][16], chromatography [17][18][19], and electrothermal (furnace) vaporization [20,21].…”

Abstract. A zoom-time-of-flight mass spectrometer has been coupled to an inductively coupled plasma (ICP) ionization source. Zoom-time-of-flight mass spectrometry (zoom-TOFMS) combines two complementary types of velocity-based mass separation. Specifically, zoom-TOFMS alternates between conventional, constantenergy acceleration (CEA) TOFMS and energy-focused, constant-momentum acceleration (CMA) (zoom) TOFMS. The CMA mode provides a mass-resolution enhancement of 1.5-1.7× over CEA-TOFMS in the current, 35-cm ICP-zoom-TOFMS instrument geometry. The maximum resolving power (full-width at half-maximum) for the ICP-zoom-TOFMS instrument is 1200 for CEA-TOFMS and 1900 for CMA-TOFMS. The CMA mode yields detection limits of between 0.02 and 0.8 ppt, depending upon the repetition rate and integration time-compared with single ppt detection limits for CEA-TOFMS. Isotope-ratio precision is shot-noise limited at approximately 0.2% relative-standard deviation (RSD) for both CEA-and CMA-TOFMS at a 10 kHz repetition rate and an integration time of 3-5 min. When the repetition rate is increased to 43.5 kHz for CMA, the shot-noise limited, zoom-mode isotope-ratio precision is improved to 0.09% RSD for the same integration time.
