Thermo Fisher Scientific Inc., the world leader in serving science, today announced additional new phases to its flagship range of Thermo Scientific Hypersil GOLD high performance liquid chromatography (HPLC) columns. The five new phases, making a total of 11, mean the Hypersil GOLDÔ family is now one of the most comprehensive ranges available. In addition to a C4 phase which broadens the scope of selectivities for reversed phase LC, the new columns also include options for the analysis of polar compounds by ion exchange, HILIC and normal phase chromatography. All phases use the same backbone of pure silica to deliver outstandingly symmetrical peak shapes, regardless of the compound or mode of analysis. The company the will showcase the Hypersil GOLD columns in Thermo Scientific hospitality suite at the Salt Palace Convention Center Salons 50BCEF during ASMS 2010. 

Hypersil GOLD C4 is a low hydrophobicity column with short alkyl chain length. This has the effect of shortening retention, making the column ideal for reversed phase separations of analytes such as proteins and peptides 

Hypersil GOLD Amino columns are well suited to the analysis of sugars and carbohydrates, demonstrating excellent properties in three modes: weak anion exchange, reversed and normal phases.  

Hypersil GOLD AX is ideal for the separation of proteins, peptides, other anionic species and polar molecules, and can be used as both an anion exchange column and for HILIC separations.  

As a highly stable quaternary amine strong anion exchange column, designed for aqueous mobile phase, the Hypersil GOLD SAX is ideally suited for use with smaller organic molecules, including nucleotides and organic acids.  

The final addition to this extensive portfolio, Hypersil GOLD Silica is a powerful and efficient tool for the analysis of non-polar and moderately polar organic compounds using normal phase LC. 

With all 11 phases available with 1.9 µm particle size, the expanded range of Hypersil GOLD columns provides chromatographers with even greater flexibility to choose the most appropriate column for their application, whether using conventional or ultra-high pressure LC systems.
