Obelisc
Two complimentary columns, Obelisc R and Obelisc N, based on Liquid Separation Cell ( LiSC ™) technology, offer a new approach to separate a variety of small molecules. Buffer concentration, buffer pH, and organic modifier concentration are three orthogonal parameters of the mobile phase that allow adjustment of column properties to separate complex mixtures.
Promix
Promix is an alternative chromatography technology for efficient resolution of peptides and proteins. The technology is based on a combination of two interactions - hydrophobic and ionic. This approach is possible due to a new type of separation media: a chemical combination of hydrophobic and ionic functional groups on a ligand bonded to a silica support. With this phase, unparalleled selectivity and peak capacity can be achieved. Independent adjustment of the amount of buffer and organic modifier creates an infinite number of separation conditions that are suitable for many types of biomolecules.
HPLC Hardware
  • SIELC Technologies is offering a patented design of capillary, analytical, and preparative hardware for HPLC.
  • Unified cylindrical shape of the columns is a signature hardware style developed and produced by SIELC.
  • Superior performance, distinguished look, and reduced hardware costs are just a few benefits of the new design.
Phlex LDS
This flexible liquid delivery system offers a new approach for adding HPLC buffers and other liquids.
  • Eliminate premixing of buffered mobile phases
  • Add modifiers such as TEA and formic acid to an SFC system
  • Use as a high-pressure injector in preparative separation chromatography
  • Eliminate contamination of HPLC pumps and degassers with buffer components
Fittings
SIELC offers a new design of fittings for HPLC. It combines reduced costs, with attractive appearance and premium performance. Two versions of fitting available for high pressure applications up to 5000 psi (350 bar) and ultrahigh pressure applications 14000 psi (1000 bar).
Some benefits of SIELC fittings: finger-tight installation, break-resistant, fully metal thread, improves heat transfer, one-size-fits-most applications, several color options.
