Lasers for 'ultimate' chromatographic sensitivity

Laser induced fluorescence detectors available at UV to IR wavelengths provide a powerful tool to detect trace levels of biological compounds in complex matrices

ESA Analytical and Picometrics have announced a joint agreement by which ESA will market the Picometrics Zetalif laser induced fluorescence detectors for HPLC and CE to its UK customers in pharmacology, neuroscience, molecular biology, toxicology, and trace analysis.

Zetalif detectors provide the ultimate in detection sensitivity, and incorporate a broad range of lasers from the UV to the infrared.

Recently, Picometrics released several new detector systems with deep UV lasers that clearly extend the utility of laser induced fluorescence detection for HPLC and CE applications.

The detector with 266nm excitation can be used to monitor the native fluorescence of a broad range of molecules at nano to picomolar concentrations without the need for derivatisation.

In addition, the 266nm system is extremely useful for the detection of commonly used amino acid derivatives.

Commenting on the new arrangement, Eddie Goodall, ESA's UK general manager, stated that "the Zetalif detector is a superb complement to our growing range of detectors.

It provides our customer base with an additional, extremely powerful tool to detect trace levels of compounds of biological interest in complex matrices.

These detectors are compatible with all existing HPLC and CE systems and are superb for solving the complex problems that our customers face".
