Procedure for Glutaraldehyde analysis

Before you start take into account the following:

• Prepare the MBTH reagent and use the pretreated reagent in the test procedure.
• Prepare the ferric chloride reagent and use the prepared reagent in the test procedure.
• Store the pretreated MBTH and Ferric Chloride reagents at room temperature for up to 1 week.

Testing procedure

Boil the water in the glass beaker. Perform dilution if reqired. After dilution, add 1 mL of distilled water to the blank tube. Pipet 1 mL of sample or diluted sample to the sample tube. Rinse the syringe with distilled water. Fill each tube to the 5 mL line with the prepared MBTH reagent and swirl to mix. Place the tubes in the glass beaker and boil the tubes for 2.5 minutes. Use the clamp to remove the tubes. Put tubes in the kit till and let tubes cool down. Add pretreated ferric chloride reagent into two tubes to the 10‑mL mark. Install the stopper on tubes and invert to mix. After 5 minutes, insert the blank tube into the left opening of the color comparator box. Place the sample tube into the color comparator box, rotate the color disc to match the color and read the value in the scale window.
