The document describes the features and functions of the Hanna Formaldehyde Test Kit, which allows for easy, quick, and safe monitoring of formaldehyde levels.
This document is the instruction manual for the Hanna Instruments HI 3838 Formaldehyde Test Kit. It outlines the contents of the kit, including reagents and equipment, and provides safety warnings regarding hazardous chemicals.
The manual details the procedure for determining formaldehyde concentration using acid titration with sodium sulfite and hydrochloric acid. It provides specific step-by-step instructions for both high-range (0 to 10%) and low-range (0 to 1%) analysis, including sample preparation and calculation methods.
| Range | 0 to 1% Formaldehyde, 0 to 10% Formaldehyde |
|---|---|
| Analysis Method | Acid titration using sodium sulfite and hydrochloric acid |
| Sample Size | 0.5 mL and 5 mL |
The analysis method is acid titration using sodium sulfite and hydrochloric acid.
Read the milliliters of titration solution from the syringe scale and multiply by 10 to obtain the percentage.
