Diamond-related materials as potential new media in separation science

Abstract

Recent progress in the development of various diamond-related materials (DRMs) has induced a strong interest in their use as a stationary phase in various separation techniques. DRMs meet many requirements for use as a stationary phase in chromatography, including excellent mechanical and chemical stability, high thermal stability, low chemical reactivity of the surface, and biocompatibility. The general physicochemical properties of diamond and the preparation of different types of DRMs are reviewed, and an overview is provided of current and possible future applications in solid-phase extraction and various separation technologies.

Improved efficiency of reversed-phase carbon/nanodiamond/polymer core-shell particles for HPLC using carbonized poly(divinylbenzene) microspheres as the core materials

“…Diamond and carbon have superior thermal, pH, and mechanical stability and accordingly are good candidates for supports for HPLC for duty under extreme operating conditions . Indeed, newly developed nanodiamond/carbon‐based core–shell materials from our group have shown some promising results .…”

Hierarchical porous graphitic carbon monoliths with detonation nanodiamonds: synthesis, characterisation and adsorptive properties

“…Diamond is known to have a high thermal conductivity with negligible thermal expansion at high temperatures [32]. Commercial nanodiamond produced via detonation synthesis and oxidative purification, also exhibits these unique thermal and mechanical properties, while retaining excellent chemical stability.…”

Direct modification of hydrogen/deuterium-terminated diamond particles with polymers to form reversed and strong cation exchange solid phase extraction sorbents

“…These properties make it an attractive material for many applications, including, perhaps, as a stationary phase/support for SPE [13], HPLC [14][15][16][17][18][19], and capillary ultrahigh pressure liquid chromatography (UHPLC) [20,21]. There are a few recent examples of diamond's use in separation science [22]. Linford and coworkers modified diamond with polyallylamine for solid phase extraction [13].…”
