Automated continuous flow analysis

The Bran+Luebbe Quaatro is an automated continuous flow analysis (CFA) system.

It uses micro-flow hydraulics with an internal diameter of 1 mm combined with a computer-controlled air injection system to deliver analysis rates of up to 120 samples per hour with low reagent consumption. The system monitors and logs system- and analysis-related parameters before and during a run. A new version of AACE software with 'one-click start-up' has been specially developed to run the analyser.

Performance is enhanced by thermostatting the entire analytical system including all hydraulic components and the detector. This provides a high level of stability. New detector electronics, optics and software reduce the detection limit to less than half that of the previous model.

It is possible to change from one method to another running at a different wavelength and run a new series of tests automatically. One console only 56 cm wide can be configured for up to four simultaneous tests. The system is compatible with existing micro-flow methods including the latest ISO standard procedures.
