Abstract: A storage container of samples for analysis is disclosed, having a cylindrical tube and two fittings adapted for connection with a syringe, mutual connection of containers in series, or closing and manufactured from a suitable plastic or glass. A column of sorbent is closed at both ends with a porous partition, screen, paper filter, or a layer of silicate or glass wool. The size of sorbent particles is 20-150 um (micrometers). The content of the storage container is protected during storage and/or transportation by closures from both sides. The sorbents which are packed into the storage container are selected from silica gel or organic copolymeric carriers of specific or nonspecific functional groups, which are purposefully chosen.
