Are there any simple tests that can be done (besides tasting) to determine if a given sample is diet coke or regular coke?

Without using taste or smell, is there a simple way to distinguish between coke and diet coke?
One possible way to distinguish: test strips that react differently to the sweeteners in each one? There are strips you can buy that will tell you if you have ketones in your urine, if a substance is an acid or a base, etc etc. Maybe something similar would work? Maybe the PH is significantly different and PH test strips could be used?
