High pH and Temperature with HALO® ELEVATE C18, 1.5 mm ID Column

A comparison made between a stainless steel hardware column and an INERT column using the same lot of HALO 90 Å C18, 2.7µm results in tailing factor and area improvement using the HALO®INERT column.

Using HALO®Elevate C18 and a high pH mobile phase obtains a great separation of drugs of abuse and metabolites without the use of a specialized stationary phase.

A 16 mer ssDNA poly dT oligonucleotide was analyzed under UV conditions on a HALO®OLIGO C18 column. The results revealed smaller peaks before and after the primary peak of interest.

The positively charged surface chemistry of HALO® PCS Peptide delivers narrower peak width, higher signal response and double the peak capacities compared to standard uncharged peptide materials

A mix of four antidepressants is separated using the HALO®PCS (positive charged surface) C18 column demonstating the improved tailing factor and efficiency when compared to a traditional (uncharged) C18 stationary phase.

The HALO® OLIGO C18 2.7 µm column outperformed an FPP Oligo C18 column in oligonucleotide separations, achieving faster separations while maintaining efficiencies comparable to a 1.9 µm FPP with more than half the backpressure.
