The most portable Liquid Fluorometer for analysing liquid samples in the field
posted on 7th Dec 2010
Exceptionally portable
The GFL-1a enables scientists, consultants and civil engineers to analyse samples quicker and easier than ever before. It weighs only 3kg - less than half the weight of older transportable fluorometers. A rugged water tight case enables the GFL-1a to access even the most remote and challenging field sites. The GFL-1a is powered by an internal, rechargeable Ni-MH battery, providing up to 36 hours of continuous field use.
Versatile
The GFL-1a is suitable for a wide variety of fluorescence monitoring applications. The unique interchangeable cuvette system allows both discrete and flow through samples to be quickly and easily analysed. Easily interchangeable filter sets are available for a wide variety of wavelengths to accommodate most tracer dyes, including Rhodamine WT and Fluoroscein, and for a host of other fluorescence applications.
Reliable and accurate
Using the latest miniaturised electronics and fluorescence detection technology, the GFL-1a provides the performance and accuracy associated with a laboratory system in a field portable device.
-
A low power consumption LED solid-state source provides fast excitation of a compound in liquid.
-
A silicon photo diode detector provides outstanding data stability.
-
A novel compact dual beam optical path provides both a reference and measurement channel to compensate for temperature, source and detector variations.
Single or multipoint calibration curves can be generated using known standards allowing real-time concentrations to be displayed. The GFL-1a can monitor compounds down to PPT levels. For example 10 PPT for fluorocein and 30 PPT for Rhodamine WT.
