Electrochemical glucose Biosensor Question

[vegeta_ban]

Hi all;

 

I conducted an experiment in my analytical chemistry class to calculate the concentration of glucose in an energy drink, such as gatorade, from known concentration glucose standards.

 

Basically the experiment was to measure the current of the standards and prepare a plot of current versus concentration.

 

I wanted to double check on here that to find the concentration of the glucose in the gatorade I would take the measured current of the unknown "drinks" and plug that data into a trendline generated from the standards with y= the concentration and x= current.

 

for example;

concentration = m*(current)+c

 

with m being slope and c being some constant generated from the trendline

 

Am I right?

 

thanks

What do you mean by current? If you are passing an electric current through a soda what you will get will have more to do with the ionic content than with glucose content.

Yes, that is it.

Yes, the trendline would be called "calibration curve", but otherwise you got the principle.
