New Interest on a little known Compound

In the past few years, 1,4 – Dioxane has gained considerable attention by researchers in the United States.

1, 4 – Dioxane is a solvent commonly found in cosmetics, toiletries, paints and varnishes. It is also used as a stabilizer for volatile compounds such as TCA.

The US EPA classifies 1,4 – Dioxane as a probable human carcinogen.

1,4 – Dioxane can enter the subsurface and potentially impact drinking water acquifers when it’s host solvent, TCA, is released through spills, leaks or historical disposable practices.

Unlike TCA, 1,4 – Dioxane readily leaches to ground water and is not expected to adsorb significantly to soil particles. Further, it is difficult to biodegrade.

Vacuum Distillation, using Method 8261 can very efficiently analyze 1,4 - Dioxane.

• NO method modifications are needed.
• Method detection limits of 0.2 ppbs are possible using VDC1012 in conjunction with HP5973 mass spec.
