C18 Low pH HPLC Columns

Description of C18 Low pH HPLC Columns

The C18 Low pH HPLC Columns are especially suitable for the separation of polarisations at very low pH to moderate pH. The pH range (0.5-8.0) is used. The LP-C18 uses a special surface treatment and stationary phase construction process. It is protected from hydrolysis at low pH and does not seal at the same time. It avoids the problem of changing the selectivity of C18 due to the easy hydrolysis of the capping reagent under acidic conditions, which makes it have excellent separation performance and stability under acidic mobile phase conditions. Saturation and longer life, 300 Å pore size for peptide and protein separation under acidic conditions. It can replace Waters XSelect HSS C18 SB, Agilent Stable Bond (SB-C18), Agilent Stable Bond (SB-AQ) and so on.
