A Practical Guide for Small and Large Biomolecule Sample Preparation

Application Notebook highlighting Liquid Chromatography techniques commonly used for monitoring Critical Quality Attributes (CQAs) in Bioprocessing Applications

This application note highlights the benefits of the LipiFiltr® cartridge for multi-class, multi-residue pesticide analysis in complex, high-fat samples.

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.

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

Over the course of 5000 injections, the HALO®Elevate C18 1.5 mm ID column demonstrates stability and robustness in the stationary phase and the column hardware, with no significant changes to the retention time, peak shape, and back pressure.
