一般描述
石墨化炭黑（GCB）可以是无孔的或多孔的。石墨化过程产生高纯度表面，具有很好的吸附和解吸（如果需要）性质。表面相互作用仅取决于色散（伦敦）力。这些粒子的特性包括：
通常，相对于碳分子筛（CMS）吸附剂，GCB 吸附剂吸附强度相对较弱，与球形石墨化聚合物碳（SGPC）吸附剂相似。我们的 Carbotrap 产品是一种 GCB 吸附剂。

A laboratory study, using generated atmosphere containing 0.14/23.3 mg/m3 of Benzene, was conducted to adapt an existing industrial hygiene monitoring method for measuring low concentrations of Benzene. This method was developed to determine concentrations of Benzene in the ambient air

In-community non-invasive identification of asthma-specific volatile organic compounds (VOCs) in exhaled breath presents opportunities to characterize phenotypes, and monitor disease state and therapies. The feasibility of breath sampling with children and the preliminary identification of childhood asthma markers were studied.

Benzene concentrations in urine samples (Cu, ng/L) from 110 workers exposed to benzene in chemical plants and gasoline pumps were determined by injecting urine supernate into a gas chromatograph. The urine was saturated with anhydrous N2SO4 to facilitate the passage

Benzene is a widely diffuse solvent (atmosphere, cigarette smoke, some foods); in the industrial environment benzene is currently present at concentrations of ppm. A valid method of biological monitoring that is easy to perform is needed for assessing occupational and
