- Аннотация: The chromatographic properties of high pressure high temperature synthesised diamond (HPHT) areinvestigated in normal phase mode of high performance liquid chromatography. Purified nonporousirregular shape particles of average particles size 1.2 um and specific surface area 5.1 m2g−1were usedfor packing 100 × 4.6 mm ID or 50 × 4.6 mm ID stainless steel columns. The retention behaviour of severalclasses of compounds including alkyl benzenes, polyaromatic hydrocarbons (PAH), alkylphenylketones,phenols, aromatic acids and bases were studied using n-hexane-2-propanol mixtures as mobile phase.The results are compared with those observed for microdispersed sintered detonation nanodiamond(MSDN) and porous graphitic carbon (PGC). HPHT diamond revealed distinctive separation selectivity,which is orthogonal to that observed for porous graphitic carbon; while selectivities of HPHT diamondand microdispersed sintered detonation nanodiamonds are similar. Owing to non-porous particle nature,columns packed with high pressure high temperature diamond exhibited excellent mass transfer andproduce separations with maximum column efficiency of 128,200 theoretical plates per meter.
