“…However, QCs recoveries for venlafaxine (using atorvastatin-d5 as IS) and for levamisol (using cocaethylene-d8) were around 130%. As it has been already reported in the literature, the use of analogues IS does not always assure an efficient matrix effects correction [40,41]. Except for the differences due to the distinct sensitivity of the two procedures, the concentrations found by both of them for the wide majority of positive samples were rather similar, supporting the applicability and reliability of our more-sensitive large-volume direct injection approach.…”

“…This is especially true for the analysis of these compounds by liquid chromatography-mass spectrometry (LC-MS) (10-12). However, even though the number of methods using LC-MS has risen dramatically, discussion of matrix suppression and enhancement that can occur during the use of LC-MS for environmental analysis and the effect it can have on quantification accuracy and precision has been discussed in a relatively small number of publications.Although the cause of matrix effects has been postulated to be natural organic matter (13), the mechanism still has not been fully resolved (14). Regardless, recent reports have shown drastic matrix effects when using LC-MS for the analysis of environmental and biological samples (14-21).…”

“…Isotope dilution has also been discussed as a means to compensate for matrix effects (14,18,19,21,23,(28)(29)(30). Although is it generally considered the most highly recommended (30) and the most versatile approach (19) for dealing with matrix effects, it has only been used in the past for the analysis of individual compounds or small groups of similar compounds and has been characterized as being costintensive and having a lack of availability (18,24).…”

“…According to Benijts et al [75] the best way to tackle matrix effect is to use appropriate internal standards, being preferred an isotopically labeled one, even though they are not regularly available and alternatively structural analogues are used [76]. On the other hand, the internal standard had to elute close to the compound of interest, showing similar behavior in the detector, in such a way that more than one of them should be used [77].…”
