Ion chromatography at an affordable price through Metrohm's 754 dialysis unit should be attractive to laboratories in the dyeing industry
Metrohm has recently launched the in-line 754 dialysis unit which allows the use of automatic sample dialysis directly before the injection of dyes into the system The special stop-flow method works with flowing sample solutions and resting acceptor solution - achieving >99% recoveries of ionic analytes from dye samples and other complex matrices.
The dialysis unit can be used in conjunction with the Metrohm modular Ion Chromatography System, this contains the 709 dual piston pump, which guarantees a constant low pulsation flow and the 732 IC detector - the most sensitive conductivity detector available on the market. Alternatively the new 790 easy to use, internet connected Ion Chromatography system is also suitable for this application and is available from Metrohm UK Ltd for the price of less than £6000, making Ion Chromatography available to all laboratories in the dyeing industry who previously could not consider the technique because of its prohibitive price.
