Metrohm has released instrumentation for the study of carbohydrates.
The 871 Bioscan with pulsed amperometric detector (PAD) is a system that will determine both whether a particular carbohydrate is present in a sample and absolute concentrations of carbohydrates.
Ion chromatography coupled with pulsed amperometric detection has been long used as a technique to study carbohydrates.
However, the ruggedness of the detector has sometimes been unsatisfactory.
Recent developments by Metrohm in hardware design have addressed this challenge.
Thorough testing has proved the ruggedness and capability of the 871 Bioscan to produce long-term stable quality results that meet the demands of modern glycobiology.
In the test, an 871 Bioscan was programmed to run an over a period of 10-hour analysis of 60 injections, shut down for a period of five hours, restart and run another 10-hour analysis involving 60 injections.
It performed these functions without fail for the entire 30-day test period.
Metrohm said that the study confirmed that crucial parameters such as drift of peak area, retention time and concentration were all within the accepted limits of up to five per cent drift over time.
