| Many commercially available NH2 ( amino ) phases are modified in order to increase stability to hydrolysis. However, this modification often leads to anomer resolution in sugar analysis. Inertsil NH2 columns are bonded in a manner which does not lead to anomer resolution, because the primary amino groups are not modified. This leads to more accurate qualitative and quantitative results. Inertsil NH2 is available in 5 micron particles in column configurations ranging from capillary to 50mm ID prep sizes. | The Inertsil 3-series represents a major advance in performance over the original Inertsil 2-Series. Inertsil 3-Series phases, including ODS-3, ODS-3V, ODS-P, ODS-EP, C8-3, Ph-3, CN-3, NH2, Diol, and SIL-100Å, are based on a purer, higher surface area silica which is specially manufactured to provide maximum bonded phase coverage. The result is a series of columns which provide excellent peak shapes using simple eluents while operating at low pressure. | |||

| * Inertsil phases are known to provide excellent results and long column life at pH levels of 9 or 10. However, optimum column life will likely be achieved by operating at a pH of between 2 and 7.5. | |||||||||
