A novel automatic apparatus for preparing a sample for analysis and a novel method for preparation of the sample are provided, whereby specified fractions of plural liquid samples can be automatically and successively collected by distillation. The apparatus comprises an inert gas charging means, a multi-way selector liquid sampler means operated by a timer, a liquid sample charging and discharging means operated by a timer, a distillation still, a fraction selector means and fraction receivers, which are connected in that order by pipe lines. The apparatus and method are especially useful, for example, for preparing a sample for analysis of a diacetyl-odor component and a sample for Kjeldahl determination method.
