Biosensing Videos

[by Nikki Scafa]

When using a TBR Free Radical Analyzer, accurate measurements of an analyte requires an accurate calibration. The calibration of nitric oxide, hydrogen peroxide and hydrogen sulfide sensors is similar. WPI oxygen and glucose sensors require different methods which will not be discussed here.

Before we begin:

• Make sure you have the following items.
• Your sensor must be polarized for the appropriate length of time.
• Your solutions are prepared as described in the manual. (NOTE: Here we will show an item checklist slide (below) before continuing the video.)
