The reason for the RQ Flex 10 displaying "LO" is that the concentration falls below the measurement range of the strips. This is essentially equivalent to "<25" displayed on the RQ Flex 20, as the only ascorbic test strips available have a measuring range of 25 - 450 mg/l Reflectoquant®. If "<25," it means the concentration is lower than the strip's analyte range or outside the detection limit. The measuring range for this assay has not changed from the old RQ Flex 10 to the new RQ Flex 20 strips.

What type of filter paper is needed to run ascorbic acid on red juices, as the application note doesn't specify?
1 answer-
The recommended filters for this purpose are simple folded filters, for instance, Whatman® prepleated qualitative filter paper, Grade 1573 1/2. Other equivalent filters may also be suitable for use.
