Since the xylose membrane also responds to glucose, the xylose
measurement is based on an algorithm that simultaneously
measures both xylose and glucose. The algorithm utilized takes
into account the responsiveness of the xylose membrane to
glucose and the slight response of the glucose membrane to
xylose.
Special Considerations:
• When measuring glucose and xylose, the glucose and
xylose sensors must be located in the same module.
• As with most analytical methods there is a concentration
range that provides optimal accuracy and precision. The
YSI xylose and glucose methods are specified
independently for performance; however these two
analytes frequently occur together.
Glucose and Xylose Specifications:
When simultaneously measuring glucose and xylose, the glucose
and xylose precision and linearity are as follows:
Precision (CV,n=10): 2% or 0.1 g/L, whichever is greater
Linearity: ±5% or 0.5 g/L, whichever is greater
