Saludos.
De antemano gracias.

The utilisation of TOF analysers offers several advantages for the
analysis of TPs, such as high resolution (more than 5000 FWHM),
mass accuracy, and full scan spectrum acquisition. A significant
characteristic of TOF instruments is a consequence of the recording
of full scan spectra. Thanks to this information, it is possible
to detect compounds (known or unknown) after analysis. This is
an important advantage since it is possible to review and to look
for additional compounds, not included in the initial analysis. One
of the problems is that there are not commercial reference standards
available for many of them. In this sense, the performance of
accurate mass measurements by TOF and the utilisation of accurate
mass databases can be applied for the elucidation and/or
identification of these compounds [134]. Thus, secondary amide
ethanesulfonic acid TPs of acetochlor, alachlor, and metolachlor
were identified by TOF-MS due to their characteristic fragmentation
and use of diagnostic ions [135]. Fig. 5 shows the ***extracted
chromatogram*** of m/z 294.195 and 163.12, which correspond to
amitraz and a fragment ion. The peak at 28.78 min is due to amitraz
(Fig. 5a), but an additional peak was observed at 12.16 min (Fig. 5b),
when m/z 163.12 was monitored. This peak was due to an amitraz
TP that had the same structure that the fragment ion observed at
28.78 min [132], observing that fragmentation patterns of parent
compound can be useful for the identification of TPs.

Fig. 5. Extracted ion chromatograms obtained form the LC/TOF-MS analysis of pear extract: (a)m/z 294.19±0.02 Da and (b)m/z 163.12±0.02 Da; (c) accurate mass spectrum
of the peak at 12.16 min, which corresponds to amitraz transformation product 1 (N-2,4-dimethylphenyl-N-methylformamidine). Reprinted from [132] copyright 2007, with

cromatograma de iones extraídos

Explanation:
La expresión completa es extracted-ion chromatogram (EIC), aunque con frecuencia se ve "el atajo" extracted chromatogram, como en este caso.

Esta expresión, sinónima de reconstructed-ion chromatogram, designa un cromatograma generado a partir de la señal correspondiente a un valor de m/z determinado o de las señales de un intervalo de m/z. Mirá estas referencias en inglés:

y esta en castellano en la que se menciona la expresión en inglés:

Por último, en la figura 1 de este artículo se presentan cromatogramas de iones extraídos correspondientes en cada caso a un solo valor de m/z:
