Publication Type: Peer reviewed scientific article Authors: Wannes Van Hassel; Julien Masquelier; Mirjana Andjelkovic; Rajkovic, Andreja Source: Separations, Volume 9, Issue 10 (2022) Keywords: food samples; quantitative analysis; analytical methods; UHPL ...
Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
thoroughly validated in terms of linearity (R2 ≥ 0.999), sensitivity (limit of quantification in the range of 0.50–5.00 μg kg−1), recovery (89.35 ± 2.67% to 110.93 ± 1.56%), and precision (RSD, 3.00–14.20%), ...
Relative response factors and multiple regression models in liquid chromatography to quantify low-dosed components using alternative standards-proof of concept: total Δ9-THC content in cannabis flowers using CBD as reference.
use of RRF s and linear relative response factor models (LRRFM) for the quantification of targeted low-dosed compounds using an alternative standard, since it is known that classical RRF s often fail in ...
