Analysis of Carbamate Pesticides Using Prominence UFLC and LCMS-2020
If multiple components need to be analyzed simultaneously, it may be difficult to achieve full separation using HPLC alone. The high
selectivity offered by mass spectrometers is especially useful in such cases. The figure below shows an example of results from analyz-
ing carbamate pesticides. Even at low 500 ppb concentrations, the mass spectrometer provided more than adequate detection sensitiv-
ity. Furthermore, high throughput can be achieved for processing multiple analytes by combining it with a UFLC system.
