User Benefits

- Simple sample preparation procedure, direct sample analysis - Sample recovery within 80 % to 120 %

Introduction

1,4-dioxane can be produced as a byproduct from certain manufacturing processes and remain in the final products, such as soaps, and detergents and other consumer and commercial products. It may be possible for 1,4-dioxane to be released into the environment from these products when they are used and washed down the drain. Exposure to a contaminated environment may result in the population being exposed to 1,4-dioxane. This can be dangerous as it has the potential to cause adverse health effects, such as liver toxicity and cancer.[1]. Therefore, 1,4-dioxane in the environment, such as water, needs to be controlled and monitored to protect the public health. In this application news, a method using static headspace coupled with GCMS has been optimized to quantify 1,4-dioxane in surface water and tap water, with reference to Application Data Sheet No. 108. The instrument detection limit has been determined to be 0.1 µg/L, with a signal-to-noise ratio (S/N) greater than 3. The limit of quantitation has been set at 1 µg/L, with S/N result greater than 30 and an area % RSD (n=5) of 4.2 %. The percentage recovery for 1,4-dioxane ranged from 100% to 120%.
