Please see our newest publication on Oligonucleotides analysis by HPLC. We recently reported a new mode of chromatography which we named Bridge Ion Separation Technique (BIST™). This technique was developed in order to obtain better separation control when working with multicharged molecules. Oligonucleotides are exactly the type of molecules that can be separated by this...Read more

The Cromite™ Analyzer represents a new generation of affordable and easy-to-learn HPLC instrumentation for schools, colleges and universities. With automated single-vial injection, high-pressure flow and UV/Vis detection capabilities, scholars can use this instrument to separate compounds, such as vitamins in juices, food dyes, caffeine and active ingredients in pharmaceutical products. The free cloud-connected software allows...Read more

Many customers have come to us with difficulties in analyzing Polyethylenimine (PEI). It is not a simple polymer to analyze with HPLC for a variety of reasons, including: – PEI is a mixture of different molecules with a large variety of differing lengths and branching structures– PEI has multiple charges in acidic and neutral pH...Read more

Dear colleagues! Welcome to our new online store at https://sielc.com/shop! We also have reconstructed our Online Applications Library to make searching simpler and quicker to help you find the method for your compound(s) of interest. If you can’t find the compound that you’re interested in analyzing in our Library, feel free to reach our R&D Lead Brad Widawer at research@sielc.com, and...Read more

An introduction to High Pressure/Performance Liquid Chromatography (HPLC), column stationary phases for HPLC, and mixed-mode stationary phases for HPLC with examples of separations of complex mixtures of molecules of interest using the novel Primesep stationary phase column series.

An introduction to the novel Newcrom mixed-mode stationary phase column series with examples of separations of many different compounds of interest.

A series of experiments separating food dyes and other coloring pigments using High Pressure/Performance Liquid Chromatography (HPLC) and the novel chromatographic method Bridge Ion Separation Technology (BIST).

Visual representation of Ion Exchange Separation, Bridge Ion Separation Technology (BIST™), and other possible ion interactions in a charged HPLC column. 1) Ion Exchange Separation (Single-Charged Ions in an Aqueous MP): The surface has a net-positive charge, and retains the single-charged negative ions. The glow around the ions represents the solvation layer that forms around...Read more
