Whether it's capture and polishing of a biopharmaceutical, reverse phase chromatography of a microbial-derived protein, or ion exchange purification of an oligonucleotide, Asahi Kasei Bioprocess offers a range of chromatography equipment that is built for you.DAC HPLC Columns-Smaller molecular weight therapeutics commonly require chromatography media with particle sizes of 10 to 15 μm for successful purification. Such media generate backpressures of 70 bar or higher. Asahi Kasei Bioprocess has been supplying DAC HPLC Columns for these applications for over two decades.HPLC Systems-Classic small molecule and small protein purification processes utilizing 10 to 15 μm chromatography media will generate backpressures of 70 to 100 bar. Such applications typically require linear gradients to achieve the desired product purity. Our HPLC Systems meet the required pressure rating while offering an array of flexible gradient technology options to fit your needs—whether it is normal phase, reverse-phase or chiral chromatography.
