Therefore, unless your sample is a relatively clean distillate that lacks these components, you can’t get accurate results if you just introduce the sample directly into the Oxidant. The kit’s Reaction bottle assembly provides a separate chamber for the sample so that only the volatile components of the sample can enter the Oxidant. Since few volatile components other than ethanol react with the Oxidant, you get a very accurate determination.\u003c\/p\u003e\n\u003cp\u003eAssay Notes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIf you are analyzing distilled spirits with very low non-volatiles content, you may use the direct method which gives results in little over an hour.
