Carbohydrate Analysis

Carbohydrate Analysis

Carbohydrate Analysis uses a phenol-sulfuric acid test method to quantify carbohydrate using ultraviolet-visible (UV/Vis) spectroscopy. This procedure is performed on extracts of reusable medical devices. It is effective at detecting blood soils that contain carbohydrates and therefore can be used to monitor the effectiveness of medical device cleaning procedures.

Testing is performed according AAMI TIR30 as part of the recommended evaluations of the efficacy of cleaning reusable medical devices. Nelson Laboratories has extensive experience testing carbohydrate residue and consulting on the results to help demonstrate device cleanliness.

Study Outline

The Carbohydrate Analysis is a quantitative test method used to detect residual carbohydrate remaining on medical devices after a contamination and cleaning process. The devices and/or materials are extracted in purified water; the extract is then processed using a phenol-sulfuric assay for detection by ultraviolet-visible (UV/Vis) spectroscopy.
