Description Application C5 5, 10μ A reversed-phase chemistry that offers greater hydrolytic stability and alternative selectivity over the classic C4 phase. Highly hydrophobic compounds. Good alternative to C8 or C18 when less retention is desired C8(2) 3, 5, 10, 10-PREP, 15μ C8 phase for excellent efficiency, peak shape and resolution. Significantly improved performance over traditional C8 phases due to high surface coverage. Slightly lower carbon load than original Luna C8 Great starting point for methods development of pharmaceuticals,nucleotides and polar compounds. Excellent for highly aqueous and LC/MS applications. C8 5, 10μ Original Luna C8 phase. Highly retentive C8 optimized for long lifetimes at extremely high pH levels. A “workhorse” for extremely high pH applications, or when a more retentive C8 is desired C18(2) 3, 5, 10, 10-PREP,15μ C18 phase. Excellent efficiency, peak shape and resolution. Slightly lower carbon load than original Luna C18. A C18 phase for virtually all HPLC applications. Range of particle sizes offers amazing versatility for capillary and LC/MS, to prep and process scale applications. Our No.1 recommended choice for HPLC method development. C18 5, 10μ Original Luna C18 phase. Very high retention, optimized for long lifetimes at extremely high pH levels. A “workhorse” for extremely high pH applications, or when longer retention is desired. Phenyl-Hexylx 3, 5, 10, 10-PREP,15μ A (patented) phenyl phase which employs a hexyl alkyl linker as opposed to the traditional propyl chain. Offers great stability as well as alternative selectivity. Remarkable selectivity for aromatic compounds. Offers selectivity advantages of both a phenyl phase and a C6 or C8 alkyl phase. Stable,reproducible alternative to traditional phenyl phases. Also very good for amine and polar compound selectivity. CN 3, 5, 10μ Cyano phase. Can be used as reversed- or normal-phase material. The use of Luna base silica results in overall phase reproducibility and performance Excellent for improving the retention of polar compounds. Extremely rapid equilibration makes it very good for rapid screening and gradient applications. Exceptional normal phase performance NH2 3, 5, 10μ Amino Phase. Can be used in reversed or normal phase modes. Stable from at pH 1.5 to 11.0 and under 100% aqueous conditions. High performance silica and bonding techniques produces a rugged, highly reproducible column.zes Excellent for sugar analysis or anionic compounds by reversed phase chromatography and for compounds capable of hydrogen bonding under normal phase conditions ?SCX ?5, 10μ A Benzene Sulfonic Acid bonded phase is used to make this Strong Cationg Exchange (SCX) column. Offers great peak shape and resolution.'5 ?Excellent for cationic and nitrogen containing analytes such as cough and cold compounds, codeine and morphine alkaloids, and drugs of abuse. Also useful for 2-dimension chromatography (SCX-RP-MS-MS) of small peptides and protein digests.
