Since the AutoAnalyzer 3 was introduced in 1997, more than 2,500 colorimeter channels have been installed.  During that time the experience gained by the Bran+Luebbe R&D and Applications teams and improvements in technology have enabled the performance to be improved, and the result of these improvements is the AA3 High Resolution Digital Colorimeter. 

Lower detection limits
The AA3 unit was already the highest sensitivity CFA colorimeter available.  When using the HR AA3 for ultra low-level methods, the lower baseline drift, higher signal-to-noise ratio and new longer flowcells will help to reduce method detection limits still further, maintaining and strengthening the AA3's position as the world's most sensitive CFA analyzer.

Easier to install and use
The new electronics incorporate a USB connection and a plug-and-play chip with an individual number so that Windows automatically recognises and uniquely identifies each colorimeter.  Together with the new hardware comes a new version of AACE which downloads the colorimeter software into Flash memory.  This is indefinitely stable in normal use, so routine downloading is eliminated and is only necessary after a software version change.
