SKU: 186006939 ACQUITY UPLC Peptide CSH C18 VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 1K - 15K, 3/pk
Waters ACQUITY UPLC CSH130 C18 1.7 µm particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for peptides using either FA- or TFA-containing mobile phases. The fact that the performance of a CSH130 C18 column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications. The VanGuard pre-column connects directly to the inlet of an eXtended Performance column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
What Are The Best Techniques For Isolating And Cleaning Analytes?
Two primary solid-phase extraction (SPE) methods are commonly employed to separate and purify target components in samples. The first method, known as retention-cleanup-elution, is utilized when the concentrations of the target chemicals are too low for reliable quantification. This approach involves retaining the analytes, cleaning up the sample matrix, and subsequently eluting the concentrated analytes for further analysis. It allows for the concentration of dilute samples and enrichment of trace chemicals. On the other hand, when the target component is present in high concentrations, a pass-through cleanup method can be chosen. In this approach, the sample is passed through the SPE sorbent to remove interfering substances, but no enrichment of the target component occurs.
