KYA Technologies Corporation, Tokyo, Japan established in 1998 to develop a range of HPLC products. The latest product HiQ sil HS is a high performance silica for rapid separations under normal reverse phase applications.
Over the last 9 years we have developed a complete range of high quality columns in the HiQ silTM series which has gained a loyal following in Japan and East Asia.
HiQ silTM HPLC columns are made from an ultra purity silica gel as the starting material. The unique manufacturing process ensures high mechanical strength and a very regular particle size whilst minimising fines to give a long life under the toughest conditions. The HiQ sil gel is manufactured in a range of particle sizes, pore sizes and with a variety of chemical surface bondings for reverse phase and normal phase chromatography.
Excellent Sample Loading
HiQ sil has been developed for sample capacity whilst retaining good peak shape. The new packing material has shown a capacity up to 3 times higher than some popular brands. The key benefit of this new packing material is evident in preparative chromatography where you can obtain
more material from fewer clean-up cycles, but it also aids regular chromatography for users that need to measure differences between very large and very small peaks; you can now improve the chromatography by loading the column with more material to improve the smaller peak’s signal to noise.
Wide pH Tolerance in Both, Acid and Alkali Mobile Phases
Reproducibility on batch-to-batch productions has been further improved due to our strict manufacturing control. The following data shows chromatograms from HiQ silTM C18HS columns taken from three different batches.
Analytical and Semi-Micro Columns
For regular analytical HPLC columns the typical sizes are still 3um and 5um particle size with either a 2mm or 4.6mm ID - Lengths do tend to vary according to application; but those assays which need high resolution still demand a 250mmL column. Now with improved resolution the 150mmL x 4.6 or (2mmID is becoming more and more popular due to lower solvent consumption, quarter the flow rate compared to a 4.6mmID) without compromising peak resolution.
Stationary phases are typically C8 and C18, but you can choose from the complete range of material including C1, C4, silica, cyano, amino and phenyl.
