SCHMIDT + HAENSCH has developed modular, computer aided automated laboratory systems, based on their conventional optoelectronic measuring instruments, which include not only polarimeters and refractometers but also a new sugar colorimeter and conductometric ash determination. They can also be upgraded by including pH measurement, balances, barcode scanners and all necessary instruments for measuring the most important values in the sugar industry and can achieve customer tailored systems with a different degree of automation. The measuring data can be collected by a data acquisition software package, processed, stored in a data bank and transmitted to a LIMS system.

A recent example is a new combined automatic determination of conductometric ash and colour (ICUMSA) for the sugar industry. The laboratory personnel only gives in the sample of crystalline sugar no further preparation is necessary ? and the sample number with a barcode scanner. The system makes automatically a solution of defined concentration (50 Brix), filtrates it and transports the sample using a peristaltic pump via flexible tubing to the COLOROMAT, where the colour measurement at 420 nm according to ICUMSA is performed. Then, the system dilutes the solution to 28 Brix and determines the conductometric ash. Both determinations are performed continuously.
