BetaBasic 18 capillary columns provide excellent chromatography for basic compounds at high pH, which allows for a wide choice of buffer selection in LC/MS applications.
BetaBasic 4 Columns
BetaBasic 4 columns: Fast analyses, including LC/MS, of all types of compounds BetaBasic 4 columns are based on a 150Å pore size, fully deactivated type B pure silica to ensure sharp peaks and excellent reproducibility for the analysis of basic compounds. Due to stable bonding chemistry and excellent surface coverage, BetaBasic 4 columns show excellent peak shape for basic compounds, and are a good first choice for compounds with poor peak symmetry on other columns. BetaBasic 4 columns give less retention than C18 or C8 phases, and are a good choice for fast analyses including LC/MS of all types of compounds. Other column dimensions and hardware designs are available. Please contact us for more information if you do not see the exact column that you are interested in.
BetaBasic 8 Columns

BetaBasicCN Columns
BetaBasic CN columns for the analysis of basic compounds BetaBasic columns are based on a 150Å pore size, fully deactivated type B pure silica to ensure sharp peaks and excellent reproducibility for the analysis of basic compounds. Due to stable bonding chemistry and excellent surface coverage, the columns exhibit exceptional low pH stability compared to other cyano phases. BetaBasic CN columns offer 'alternative' selectivity due to dipole-dipole and dipole-induced dipole interactions, and can be used in normal or reversed phase separations. They show excellent peak shape for basic compounds and are a good first choice for compounds typically considered difficult to analyze. BetaBasic CN columns can be used in normal or reversed phase modes. Other column dimensions and hardware designs are available. Please contact us for more information if you do not see the exact column that you are interested in.
BetaBasic Phenyl Columns
BetaBasic columns are based on a 150Å pore size, fully deactivated type B pure silica to ensure sharp peaks and excellent reproducibility for the analysis of sbasic compounds. Due to stable bonding chemistry and excellent surface coverage, BetaBasic Phenyl columns exhibit exceptional low pH stability compared to other phenyl phases. BetaBasic Phenyl columns offer 'alternative' selectivity compared to alkyl chain phases (C18) due to pi-pi interactions from the benzene ring, and give excellent peak shape for basic compounds. The BetaBasic range of columns are a good first choice for compounds typically considered difficult to analyze.
BioBasic Columns
Thermo Scientific BioBasic HPLC columns are made to the highest specifications for reliable separations of a wide range of proteins, peptides and other biomolecules.
BioBasic 18 Columns BioBasic 18 columns for reliable separations of proteins and peptides
BioBasic 18 columns provide exceptional reliability for separations of proteins, peptides, and other biomolecules through a combination of high purity silica and reproducible, stable bonding. The proprietary bonding procedure ensures high phase coverage that gives improved resolution with shorter column lengths when compared to other 300Å columns. BioBasic packings are also designed to give longer lifetimes and withstand harsh mobile phase and clean-up conditions. BioBasic 18 is also avaiable in 10µm particles size for preparative separations. Other column dimensions and hardware designs are available, including capillary columns suitable for multi-dimensional LC/MS analyses. Please contact us for more information if you do not see the exact column that you are interested in.

BioBasic AX Columns BioBasic AX columns give superior reproducibility, stability and efficiency.
New BioBasic AX (weak anion exchange) columns have a polyethyleneimine (PEI) ion exchange group and a polymer coating, specifically designed to give robust and clean performance in ion exchange of acidic proteins and peptides. 300Å pore size BioBasic AX columns provide exceptional reliability for ion exchange separations of acidic proteins, peptides, and other biomolecules through a combination of high purity silica and reproducible, stable bonding. The proprietary bonded phase ensures clean ionic fractions can be collected, allowing shorter column lengths to be used when compared to other ion exchange columns.
BioBasic SCX Capillaries BioBasic SCX columns are recommended for multi-dimensional proteomic analysis
BioBasic SCX capillary columns are available in high efficiency KAPPATM capillary columns. They have a standard female endfitting and are available in 500µm, 320µm, 180µm, 100µm and 75µm ID capillaries with a stainless steel sleeve for a rugged design that can be used with standard column connectors. BioBasic SCX columns are also recommended for multi-dimensional proteomic analysis, where a 100 x 0.32mm KAPPA capillary column is used to separate a protein into fractions prior to analysis by reversed-phase HPLC.
BioBasic SCX Columns BioBasic SCX columns for separations of proteins, peptides, biomolecules
BioBasic SCX columns provide exceptional reliability for ion exchange separations of basic proteins, peptides, and other biomolecules through a combination of high purity silica and reproducible, stable bonding.

BioBasic SCX columns are also recommended for multi-dimensional proteomic analysis. A 100 x 0.32mm KAPPA capillary column can be used to separate a protein into ionic fractions. The fractions are further analysed by LC/MS/MS using a reversed-phase BioBasic 18 capillary column (see BioBasic SCX Capillary Columns for further information).
BioBasic SEC (Size Exclusion) Columns BioBasic columns for separations of proteins, peptides and other biomolecules
BioBasic SEC columns are available in four pore sizes (60, 120, 300 and 1000Å) to cater for separations of samples from 100 to 10,000,000 molecular weight. The columns are based on porous silica particles coated with with a hydrophillic polymer for superior column lifetimes. They give superior resolution with 100% aqueous or organic eluents, and do not swell or shrink with changes in solvent, showing higher peak capacityies than polymer-based SEC columns. The polymer coating eliminates secondary interactions so that samples are separated based stricly on their size in solution. The columns are offered in a standard 300 x 7.8mm size, and also 150 x 7.8mm for faster separations, as well as a 30mm length guard column to maximize column lifetimes.
HyPURITY ColumnsThe 190Å pore size of HyPURITY columns provides extensive chromatographic options from small molecules to large peptide analyses. Based on highly-pure silica, HyPURITY columns offer an excellent choice for new method development.
