Packing material for solid phase extraction and solid phase exraction method

An object of the present invention is to provide a packing material for solid phase extraction, ensuring excellent recovery of not only a hydrophobic substance but also an ionic substance by having hydrophobicity and an ion exchange group at the same time, and a solid phase extraction method, a packing apparatus, and a method for treating a sample, using the packing apparatus. A packing material for solid phase extraction of the present invention is a particle obtained by copolymerizing a hydrophobic monomer (A) and a hydrophilic monomer (B) and introducing thereinto an ion exchange group, in which the ion exchange group is introduced without impairing the hydrophobic site. The present invention also provides a solid phase extraction method, a packing apparatus for solid phase extraction and a method for treating a sample, using the packing material.

Mask securing device

A respirator assembly has a respirator mask and a separate bracing device. The bracing device has a pressure element mountable over a frontpiece of the respirator mask, which bears against that frontpiece to hold the respirator mask against the face of a user. The bracing device also has two connection portions, each having one end attached to the pressure element and the other end being for attaching the bracing device to a helmet worn by the user. The connection portions are extendable. Thus, shortening or distending the connection portions reduces the distance between the helmet and the respirator mask and thereby causes the pressure element to bear against the frontpiece of the respirator mask, compressing the user's head between the helmet and the mask and thereby holding the mask against the user's face.

Graphene adsorbing material, preparation method therefor and application thereof, and cigarette filter tip and cigarette

ActiveUS20180228209A1Not affecting smoking taste of smokeReduce harmGas treatmentCigar manufactureFiberHazardous substance
A graphene adsorbing material, a preparation method therefor and application thereof, and a cigarette filter tip and a cigarette are provided. The graphene adsorbing material comprises a fiber carrier, graphene and doped elements wherein the graphene and the doped elements are loaded on the fiber carrier and the doped elements comprise at least one of Al, Si and Fe. The graphene adsorbing material is obtained by contacting the fibers with the graphene material to load the graphene material on the fibers. By introducing the graphene and the doped elements in the fiber carrier, harmful substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke can be specifically adsorbed, filtered and removed; while nicotine and the other harmless substances are retained, and thus the smoking taste of a cigarette is not affected. The cigarette filter tip can effectively adsorb cancerogenic substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke to reduce harm of smoking; meanwhile, the pleasure of smoking and the mellow taste of the smoke are not affected. Besides, the graphene adsorbing material can also prevent the phenomenon that a cigarette holder gets mildewed due to humid environment and the other factors.
