J. Liq. Chromatogr. Relat. Tech. 38, 381-389 (2015). Review of the materials, techniques and instruments for the detection and quantification of radiolabeled compounds by planar radiochromatography. Special reference is made to sample preparation, stationary phases (including instant TLCD sheets), initial zone application, mobile phases, stationary phase development, and zone detection and quantification.

Trends Anal. Chem. 82, 22-34 (2016). Review of recent developments in the field of compact mass spectrometers as chromatographic detectors, including features to extract individual TLC zones and deliver them directly to the electrospray ionization (ESI) or atmospheric-pressure chemical ionization (APCI) source.

Trends Anal. Chem. 82, 68-88 (2016). This review describes the application of ambient mass spectrometry for the analysis of pharmaceutical products and herbal medicines, including coupling TLC to DESI–MS for the analysis of analytes separated on TLC plates. The review also describes coupling TLC with direct analysis in real time (DART)-MS, which is easily achieved by positioning a TLC plate between the DART source and the MS inlet.

Trends. Anal. Chem. 98, 79-94 (2018). Review of essential protocols for the quantification of dairy-related contaminants, including the application of HPTLC for the determination of residual pesticides such as chlorpyrifos, bifenthrin, deltamethrin, cyhalothrin and imidacloprid and antibiotics such as cephalosporin.

Trends Anal. Chem. 112, 87-101 (2019). Review of high-resolution mass spectrometry (HRMS)-based techniques and their application in the analysis of secondary metabolites covering papers published between 2015 and 2018. The benefits of HPTLC-hyphenations in the discovery and characterization of active natural compounds were also discussed, including Orbitrap MS-coupled methods and the use of TLC in combination with stand-alone HRMS instruments.
