Could y'all be so kind as to help us "reading" the graph of cyanuric acid in the control sample and the contaminated sample of cat food from this report...

It's the 4th set down in the image.

http://toxsci.oxfordjournals.org/cgi/co ... 1/251/FIG1

Is that spikes of the contaminant in the control sample or noise?

Or??...

Thanks for your help.
