WebLiquid chromatography with tandem mass spectroscopy (LC–MS/MS methods are the most suitable for identification and quantification of TTX and its analogues, with LOQs between 0.1 and 25 µg/kg. (Scientific opinion on the risks for public health related to the presence of tetrodotoxin (TTX) WebNow, let’s look at the results. Figure 3 shows the LC-MS/MS separation of glyphosate, AMPA, and glufosinate on a short hybrid ion-exchange/HILIC column (the dimensions are 2.1 x 30 mm, 2.7 µm superficially porous particle). As you can see, we have reduced the cycle time to a mere 8 minutes with excellent retention, resolution, and peak shape.
