YSI has announced its improved xylose membrane for YSI 2700 and YSI 7100 analysers, specifically developed for biofuels applications to monitor fermentation progress in cellulosic ethanol research.
This membrane allows the analysers to perform rapid simultaneous measurement of glucose and xylose.
The xylose analytical performance parameters include greater measurement range 0-50g/l, improved low-level detection and precision now less than two per cent with improved linearity of +/-10 per cent or +/-0.5g/l.
With minimal or no sample preparation, results are available in one minute.
There is no need to dilute the sample.
