“…Commonly used HRMS detectors include orbitrap MS, ion trap, time-of-flight mass spectrometry (TOF MS), and FTICR. FTICR/MS has an extremely high resolution, but its high data acquisition speed limits its on-line coupling with UPLC [ 68 , 69 , 70 , 71 ]. Time-of-flight mass spectrometry has innate performance advantages over quadrupole mass spectrometers.…”

“…The components in the capillary are separated according to their charge, molecular size, isoelectric point, and other characteristics. It has a high separation efficiency and can afford unique advantages in the separation of small molecules [ 56 , 57 , 58 , 71 ]. Lanaro et al [ 57 ] developed capillary electrophoresis (CE) combined with diode-array detection (DAD) to monitor PQ concentration in different biological samples including plasma, urine, and oral fluid.…”

“…Chen et al [ 71 ] developed a microcapillary sampling (MCS) method coupled with matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance mass spectrometry (MALDI–FTICR–MS), which was used to detect the PQ concentrations in living vegetables. After the optimization of the parameters, there was a wide linear range (7.81–500 μg/kg) and a low limit of detection (0.1–0.9 μg/kg) for PQ and DQ.…”

Paraquat (PQ) and diquat (DQ) are quaternary ammonium herbicides which have been used worldwide for controlling the growth of weeds on land and in water. However, PQ and DQ are well known to be toxic. PQ is especially toxic to humans. Moreover, there is no specific antidote for PQ poisoning. The main treatment for PQ poisoning is hemoperfusion to reduce the PQ concentration in blood. Therefore, it is essential to be able to detect PQ and DQ concentrations in biological samples. This critical review summarizes the articles published from 2010 to 2022 and can help researchers to understand the development of the sample treatment and analytical methods for the determination of PQ and DQ in various types of biological samples. The sample preparation includes liquid–liquid extraction, solid-phase extraction based on different novel materials, microextration methods, and other methods. Analytical methods for quantifying PQ and DQ, such as different chromatography and spectroscopy methods, electrochemical methods, and immunological methods, are illustrated and compared. We focus on the latest advances in PQ and DQ treatment and the application of new technologies for these analyses. In our opinion, tandem mass spectrometry is a good choice for the determination of PQ and DQ, due to its high sensitivity, high selectivity, and high accuracy. As far as we are concerned, the best LOD of 4 pg/mL for PQ in serum can be obtained.

“…Pipetting of the sample onto the target plates/anchor chips can be performed manually with a glass or plastic tip (in the latter case, the probability of contamination of the sample with organic contaminants is often significantly increased) or automatically with special devices [19][20][21][22][23][24][25][26][27][28][29] . Literature on MALDI sampling is extremely large [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] .…”

This article proposes to analyze the formation and “morphogenesis” during desolvation of drops on MALDI targets and target chips using 2D correlation spectral analysis based on the two-dimensional Fourier transform and wavelet spectroscopy methods in the real and imaginary regions. The results of the correlation-spectral and wavelet analysis are shown in the illustrations in the text of the article.
