General description
TSKgel NH2-100 DC column connects directly to TSKgel reversed phase columns. The DC in TSKgel NH2-100 DC emphasizes this Direct Connect aspect. This column has the same packing material as the TSKgel NH2-100 columns, so therefore shows high retention for hydrophilic compounds/ions. A male-type outlet endfitting enables the direct connection to the screw-type endfitting of a TSKgel reversed phase column. This allows for the simultaneous (linear) gradient separation of an active pharmaceutical ingredient (API) and its counterion without the loss of column efficiency normally experienced when connecting two columns with capillary tubing.
