Product Descriptions and Parts Number
Silica columns
Silica columns are normal phase columns for flash purification of organic compounds with sample loading up to 10% of packed mass. Both standard and High Performance (HP) columns are packed with high purity silica gel with narrow particle size distribution and narrow pH range (6.8-7.2) and special mechanical packing technology enable significant advantages over leading competitors in purification efficiency, resolution, and column reproducibility. The columns are compatible with all purification systems.

SuperSep™ Empty Flash Cartridge Housing
Luknova provides proprietary empty flash cartridges to meet client specific needs. A variety of process and approaches can be employed to achieve the leak-free column assembly, such as clamping the filled column securely to a ring stand when mount the sealing insert, align the perforated cap, and tighten the perforated cap onto the column body container. Luknova utilizes custom-made instrument to pack tight and leak-free flash columns. We also provide custom packing services with client media.

SuperSep Solid Load Cartridges (compatible with ISCO)
Luknova® SuperSep Solid Load Cartridges are used to improve the separation efficiency and compound purity for low-solubility sample purification by eliminating the impurities and minimizing the byproducts. For low-solubility sample, loading the empty cartridges with a slurry mixture of the dissolved low-solubility sample and supporting media. Prior to the cartridge loading, the vacuum vaporization of the solvent typically improves the purification efficiency. The dissolved sample can be loaded directly onto the top of the prepacked load cartridges packed with Silica, Alumina, C18, Celite, Cyano, Diol, Amine, SAX, and SCX.

Adaptor and Accessories
For Biotage Horizon, SP1, SP4, and FlashMaster systems, less expensive line connection as shown below (following left side) is recommended by using Luer fittings and lines. The top connection line which comes from the pump outlet connects to the column inlet via a red-black adapter (P/N: LK1687). The column outlet is connected with adaptor bottom section (P/N: LK1689) to the UV detector. The Luer Lock Adapters are used to connect column either inlet, outlet, or both as shown below (right side) when needed, such as for stacking multiple columns and fitting into used or refurbished purification instruments.

SuperSep™ C18 Columns Experimental Tips
System Preparation: C18 columns operate under reversed phase conditions (i.e., 100% Water ? 100% Acetonitrile). When ready to switch from normal phase to reversed phase purification, make sure (i) air purge solvent A and B lines, (ii) flush solvent A and B lines with high purity acetonitrile, methanol, or ethanol, and (iii) flush solvent A line with aqueous solvent thoroughly.
C18 Column Preconditioning: Use six to seven column volumes of 1/1 water/acetonitrile (or water/methanol) mixture to flush the C18 column prior to first and immediate use. In an alternative way, pre-equilibrate with twice column volume (CV) of 100% acetonitrile and store for 1hr prior to use. End of the Run Care and Storage: At the end of the separation run, wash the column with four column volumes 100% acetonitrile or organic solvent B. It is recommended that only after the wash with 100% organic solvent, the purification can be returned to the condition of the start of the run and start the next run. At the end of the run, flush the column with four column volumes of 80% organic solvent + 20% water and capped wet to store for future use. |

The high purity silica gel with narrow particle size distribution and narrow pH range and special mechanical packing technology enable significant advantages over leading competitors in purification efficiency, resolution, and column reproducibility. A representative purification chromatography on ISCO system is shown below :

Performance comparison of Luknova SuperSep™ standard and HP with competitor 12g columns
The comparison of Luknova SuperSep standard (averaged 50 micron particle size) and high performance (HP) (averaged 25 micron particle size) with those from leading competitors are shown below. Luknova standard column showed excellent performance as shown sharper peaks and reduced peaks overlapping.

Sample Information:
Undisclosed real sample. A mixture of tertiary alcohols from reactions of boronic acid coupling to an aryl bromide and a second reaction of sonogashira reaction of an acetylene with an aryl bromide. All the products and impurities from the reactions contain alcohols. Fraction Purity: A 96.96% reported purity of the fraction based on Mass Spectroscopy analysis. Flash Column Luknova SuperSep™ standard 120gram silica gel flash column. |
SuperSep™ C18 Columns Experimental Tips
System Preparation: C18 columns operate under reversed phase conditions (i.e., 100% Water ? 100% Acetonitrile). When ready to switch from normal phase to reversed phase purification, make sure (i) air purge solvent A and B lines, (ii) flush solvent A and B lines with high purity acetonitrile, methanol, or ethanol, and (iii) flush solvent A line with aqueous solvent thoroughly.
C18 Column Preconditioning: Use six to seven column volumes of 1/1 water/acetonitrile (or water/methanol) mixture to flush the C18 column prior to first and immediate use. In an alternative way, pre-equilibrate with twice column volume (CV) of 100% acetonitrile and store for 1hr prior to use. End of the Run Care and Storage: At the end of the separation run, wash the column with four column volumes 100% acetonitrile or organic solvent B. It is recommended that only after the wash with 100% organic solvent, the purification can be returned to the condition of the start of the run and start the next run. At the end of the run, flush the column with four column volumes of 80% organic solvent + 20% water and capped wet to store for future use. |
