Far-infrared (FIR) data on the optical properties of graphite are presently lacking. An important step towards filling this gap was taken by Kuzmenko et al. who measured, on highly oriented pyrolitic graphite at normal incidence and from 10 to 300 K, the in-plane dielectric functions from 0.3 to 200 μm, and the reflectance between 0.3 … havoc firearms

WebAttributes of these ferrule materials are summarized in Table 1. Graphite and polymeric ferrules have several advantages for use in gas chromatography over metal (especially hard metal) ferrules: They can seal against imperfect surfaces with little force. They can be used with virtually any type of tubing or column including glass and fused silica.
