2 Gemini -NX Axia Packed Technology Improves Yield, Throughput, and Column Lifetime Ideal Purification Platform While reversed phase separation using HPLC remains one of the most efficient ways of obtaining large-scale purification, several limitations can impact overall productivity: Column loading capacity Media durability Column lifetimes By choosing Gemini-NX in Axia packed preparative columns, these limitations can be overcome; purification yield and throughput can significantly increase. An Equation for Success The success begins with the Gemini-NX media. Through a patentpending process of grafting a network of ethane crosslinking on a pure silica core, a new type of media is created that boasts high column efficiencies, strong hydrophobic selectivity, and a durable ph stability of -. Axia technology complements the package with a self-contained axialcompression piston that locks the media bed in place and eliminates premature column failure due to bed collapse, resulting in a high efficiency, long lasting preparative column. Together, these two technologies complete the equation for increasing productivity for preparative purifications. 009 Phenomenex, Inc. All rights reserved.

3 Increase Sample Loading and Throughput with High ph ph Selectivity Increase loading capacity Sharpen peak shapes Increase productivity Most pharmaceutical compounds are ionizable (either acidic or basic). The ionization state of a compound greatly affects its reversed phase retention. When compounds are ionized, they exhibit less retention. When compounds are neutral, they exhibit greater retention. The ionization state of a compound can be controlled through the mobile phase ph, simply by determining the pk a and adjusting the ph accordingly: For bases, adjust mobile phase ph units above the pk a to neutralize the charge* For acids, adjust the mobile phase ph units below the pk a to neutralize the charge* Because the compound ionization state significantly impacts its reversed phase selectivity, preparative purifications can be optimized to increase yields. When the basic compounds shown in the separation below (diphenhydramine; pk a 8. and propranolol; pk a 9.0) are run under acidic conditions, reversed phase selectivity is minimal, due to the decrease in overall hydrophobicity of the solutes. By increasing the mobile phase ph two units above their respective pk a values to 0., both bases are neutralized increasing reversed phase selectivity, resulting in greater overall resolution and increased sample loading.

Increasing ph allowed higher mass loading, reducing the number of purification cycles required. The increased resolution at the higher ph also resulted in higher purity and yield for desired basic compounds. * For more detailed information, request technical note TN-00, Impact of ph on the Purity and Yield for Preparative Separations.

4 Gemini -NX ffers Extreme Durability and Robustness in Ever-Changing Environments Rugged Media In today s demanding environments, columns need to deliver more. Consistent performance and long lifetime in the presence of harsh conditions is a requirement for columns that are used routinely for method development or in open-access systems. Gemini-NX columns have been subjected to the most extreme conditions (shown below) to demonstrate their place as your number one choice for reversed phase methods, analytical to preparative.

6 What is Axia Technology? Why Do I Need It? Dependable Axia Technology Benefits: Eliminates media collapse for longer lifetimes Drastically decreases column variability Achieves proper packing density and uniformity Axia technology is beautiful, both on the outside and on the inside. It s an improved, more repeatable packing process that has been recognized by the scientific community as a unique, innovative technology with numerous benefits. The Axia packing process provides preparative chromatographers significant improvements in column lifetime, efficiencies, and peak symmetries that are on par with analytical separations. verall column-to-column consistency is also dramatically improved. With Axia packed columns, the ideal sorbent density is custom calculated and automated for each chemistry and column size. Computer control of the entire process ensures the proper sorbent density and uniformity for an excellent performing preparative column every time. No other company offers this packing technology. 006 R&D 00 Award Recipient We invite you to view the award winning packing process at: Calculating your scaling factor Scaling a separation to meet preparative demands requires the redimensioning of chromatographic parameters such as flow rate/column ID/sample load.
