HI3838 Formaldehyde Test Kit The HI3838 is a titration-based chemical test kit that determines the formaldehyde concentration in two ranges: 0.00 to 1.00% and 0.0 to 10.0%. The HI3838 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 110 tests. • Complete setup · All required materials are included with the test kit, such as the sample beaker, indicator and reagent bottles, and calibrated syringe. • High resolution · Readings from 0.00 to 1.00% are determined to 0.01% resolution. · Readings from 0.00 to 10.0% are determined to 0.1% resolution. • Replacement reagents available · There is no need to buy a new kit when reagents are exhausted. The HI3838-100 can be ordered to replace the reagents supplied with the kit. Signicance of Use Formaldehyde is an important organic compound used to make many materials and chemical compounds. Its role in many industries varies from holding dyes onto fabrics, to assisting in the electroplating of metals. Formaldehyde is also used in biological preservation, drug testing, and photograph development. Each application uses dierent levels of formaldehyde and requires monitoring to optimize its given purpose. Formaldehyde is also a large consideration for human health. Due to its widespread use, there are regulations in place for formaldehyde limits within workplaces to avoid overexposure. HI3859 Glycol Yes/No Test Kit Use the HI3859 glycol standard 0.025% included in the kit to easily recognize a positive result in the form of an intense purple color. Ethylene glycol and other glycols are determined by a two-step reaction: Step One: Glycol is oxidized to two carbonyl groups under acidic conditions. Step Two: The carbonyl groups react with the indicator to give a highly colored solution. The test detects traces of glycol above 30 ppm.
