[PMID: 37056215 DOI: 10.1002/mas.21845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 03/07/2023] [Accepted: 03/13/2023] [Indexed: 06/19/2023]
Abstract
In food analysis, conventional one-dimensional liquid chromatography methods sometimes lack sufficient separation power due to the complexity and heterogeneity of the analyzed matrices. Therefore, the use of two-dimensional liquid chromatography (2D-LC) turns out to be a powerful tool to consider, especially when coupled to mass spectrometry (MS). This review presents the most remarkable 2D-LC-MS food applications reported in the last 10 years, including a critical discussion of the multiple approaches, modulation strategies as well as the importance of the optimization of the different analytical aspects that will condition the 2D-LC-MS performance. The presence of contaminants in food (food safety), the food quality, and authenticity or the relationship between the beneficial effects of food and human health are some of the fields in which most of the 2D-LC-MS applications are mainly focused. Both heart-cutting and comprehensive applications are described and discussed in this review, highlighting the potential of 2D-LC-MS for the analysis of such complex samples.

Abstract
Flupyradifurone (FPF) is a neonicotinoid insecticide that effectively controls the spread of various pests. In this study, we established an immunochromatographic assay based on a highly specific and sensitive anti-FPF monoclonal antibody (mAb) to screen for FPF residues in grapes, blueberries, and tomatoes. The cut-off value for the immunochromatographic assay was 5 mg/kg for grapes and 10 mg/kg for blueberries and tomatoes. The calculated limit of detection of the immunochromatographic assay was 0.009 mg/kg, 0.033 mg/kg, and 0.040 mg/kg for grapes, blueberries, and tomatoes, respectively. The recovery rates of the immunochromatographic assay were 97.0-108.2 % in grape samples, 90.9-105.1 % in blueberry samples, and 94.0-103.7 % in tomato samples, and the detection results were highly consistent with LC-MS/MS results. Therefore, this immunochromatographic assay was an effective and rapid tool for screening for FPF in grapes, blueberries, and tomatoes.

Talanta 2024; 266:124918. [PMID: 37454518 DOI: 10.1016/j.talanta.2023.124918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 07/03/2023] [Accepted: 07/05/2023] [Indexed: 07/18/2023]
Abstract
Liquid chromatography-mass spectrometry (LC-MS) is currently the gold-standard technique for the analysis of non-volatile small organic molecules. However, one-dimensional liquid chromatography (1D-LC) cannot efficiently deal with mixtures of analytes with different physicochemical properties and, thus, specific chromatographic behaviour. As an alternative, this work proposes a two-dimensional liquid chromatography/high-resolution mass spectrometry (2D-LC-HRMS) approach for the simultaneous analysis of compounds with different polarities. It is based on the combination of hydrophilic interaction liquid chromatography (HILIC) in the first dimension (1D) and reversed-phase chromatography (RPLC) in the second dimension (2D), employing the heart-cutting methodology. The coupling between 1D and 2D was performed by a multiple heart-cutting (MHC) interface equipped with an active solvent modulation (ASM) valve. The aim of the study was the development of a 2D-LC methodology able to (i) acquire the 1D and 2D content by MS in a single analytical run, avoiding the loss of information caused by the MHC algorithm for filling the sampling loops; (ii) overcome the breakthrough problem caused by solvent incompatibility, modifying the 2D gradient during the ASM phase for this purpose. To evaluate the 2D-LC approach, pesticide residue analysis was proposed, selecting 20 pesticides covering a wide range of polarities (log Kow from -3.2 to 4.3) and including some of the so-called single residue method pesticides because of the difficulty of including them in 1D-LC multi-residue methods with satisfactory chromatographic resolution. The proposed strategy was to transfer in a single cut the void volume from the HILIC separation (consisting of the nonpolar pesticides) to the 2D for analysis under RPLC conditions. The developed assembly was assessed in a vegetable matrix (tomato) employing a hybrid QuEChERS/QuPPe sample treatment based on acetonitrile and methanol extraction. The proposed setup may be extended for 2D-LC applications where it is essential to acquire the entire content of both dimensions in a single data file just by coupling a selection valve to the MHC interface.

Abstract
Due to the growing trend of organic food, there is still concern over the use of chemicals and pesticides in agriculture. In recent years, several procedures have been validated for the control of pesticides in food. In the present research, a comprehensive two-dimensional liquid chromatography coupled with tandem mass spectrometry is proposed for the first time for a multi-class analysis of 112 pesticides in corn-based products. Notably, a "reduced" QuEChERS-based method as extraction and clean-up procedure prior to the analysis, was successfully employed. Limits of quantification values were lower than the ones fixed by the European legislation; intra-day and inter-day precision were lower than 12.9% and 15.1%, respectively (at the 500 μg/kg concentration levels). Over 70% of the analytes provided recoveries between 70% and 120% range (at 50, 500 and 1000 µg/kg concentration levels) with standard deviation values below 20%. In addition, matrix effect values were in the range between 13% to 161%. The method was applied to the analysis of real samples, and three pesticides were detected at trace levels in both samples. The findings of this work pave the way for the treatment of complex matrices such as corn products.

Abstract
Chlordimeform (CDM) is a broad-spectrum and highly effective insecticide and acaricide used to control pests in agriculture. We produced two monoclonal antibodies (mAbs) against CDM and developed an immunochromatographic assay to screen CDM in cucumbers and tomatoes. MAb 4A3 had high sensitivity with a 50% inhibitory concentration of 0.287 ng mL-1. The assay had a cut-off value of 25 μg kg-1 and a visual limit of detection (vLOD) of 1 μg kg-1 in cucumbers and a cut off value of 50 μg kg-1 and a vLOD of 2.5 μg kg-1 in tomatoes. The calculated limit of detection (cLOD) in cucumbers and tomatoes was 0.115 μg kg-1 and 0.215 μg kg-1, respectively. The recovery rates were 97.9% to 106.9% for cucumbers and 97.8% to 107.4% for tomatoes, consistent with the results obtained from indirect competitive ELISA. Our findings showed that the immunochromatographic assay is an efficient and accurate method for CDM detection in cucumbers and tomatoes.

Abstract
UNLABELLED Objective: Chlordimeform is a chemical pesticide that is highly carcinogenic and toxic. The purpose of this study was to establish an enzyme-linked immunosorbent assay (ELISA) method for the detection of chlordimeform in aquaculture and fish farming. METHODS Chlordimeform was coupled with bovine serum albumin (BSA) and ovalbumin (OVA) as carrier proteins. A chlordimeform-BSA conjugate was used as an immunogen, and chlordimeform-OVA was used as a coating antigen. Chlordimeform-BSA was used to immunize rabbits, and a polyclonal antibody was prepared. An indirect competitive enzyme-linked immunosorbent assay (IC-ELISA) was established to detect chlordimeform. RESULTS The working range of the established IC-ELISA method for chlordimeform detection was 1-20 ng/mL. The IC50 was 3.126 ng/mL, and the lower limit of detection (LOD) of chlordimeform was 0.637 ng/mL. The recovery of chlordimeform from spiked water samples ranged from 81% to 107%. CONCLUSION An anti-chlordimeform polyclonal antibody was successfully developed, and a novel IC-ELISA was established to detect chlordimeform in aquaculture.

Abstract
In this study, a fully automated two-dimensional liquid chromatography (2D-LC) system was used for the investigation of the clean-up effect and was compared with a traditional Quick Easy Cheap Effective Rugged and Safe (QuEChERS) liquid chromatography (LC) method. The focus of those investigations was on negative electrospray ionization (ESI) mode. For that purpose, matrix fingerprinting profiles were created. The results allowed a comparison of both methods regarding the estimation of the number and the polarity of detected compounds. Moreover, the results of the present study were compared with the results generated in positive ESI mode (presented in a previous study). Furthermore, the two methods were compared with regard to matrix effects (ME) of 321 analytes in positive ESI mode and 96 analytes in negative ESI mode. In general, fewer compounds could be detected when 2D-LC and/or the negative ESI mode was used. Especially, very polar compounds with m/z values >1000 could be separated and could not be detected anymore when 2D-LC was applied. Furthermore, the best results were obtained for most analytes when 2D-LC was used, although the extent of ME seemed to be higher with 2D-LC.

Abstract
In this study, a clean-up approach using a two-dimensional liquid chromatography (2D-LC) consisting of a hydrophilic interaction liquid chromatography column and a reversed phase column was investigated. A fully automated 2D-LC system was used and compared with a traditional quick, easy, cheap, effective, rugged, and safe (QuEChERS) liquid chromatography (QuE-LC) method. The comparison was based on the results of a validation of selected analytes. It was investigated whether the detectability of analytes could be improved by the use of the 2D-LC. On the basis of these results, the relative detection rates were determined for every matrix. By means of those detection rates, the matrices were categorized regarding their complexity. Furthermore, the applicability of the 2D-LC was tested by participation in the European Proficiency Test in Fruits and Vegetables Screening Methods. In order to evaluate the separation and the elution profile of matrix components, multivariate data analysis was applied. For this purpose, ten matrices were processed in accordance to a QuEChERS protocol and the protocol for 2D-LC analysis. Moreover, the reagent blanks of the corresponding matrix were processed and analyzed by QuE-LC and 2D-LC. The results allowed evaluating the number of detected compounds for both methods. Additionally, the influence of compounds originating from reagent blanks can be estimated. In general, less compounds could be detected when 2D-LC was used. Especially, these were very polar compounds and compounds with m/z values >1500. These compounds seem to originate primarily from the used reagents especially from the citrate salts. However, the most of these compounds could be separated and were not detectable any more when 2D-LC was used. The results of the comparison based on validation and participation in the European Proficiency Test also show a better detectability for the most analytes with 2D-LC.
