SKU: 186006985 ACQUITY APC AQ BEH Column, 200Å, 2.5 µm, 4.6 mm X 150 mm, 3K - 70K, 1/pk
ACQUITY APC AQ columns are designed to provide highly efficient size-based separations for water soluble polymer characterization. The sorbent uses patented Ethylene Bridge Hybrid (BEH) technology to provide a mechanical strong packed bed that resists shinking and swelling for easy mobile phase solvent switching. The expected molecular weight range for this column is approximatley 3, 000 - 70, 000 g/mole.
What Is The Average Timeframe It Takes To Change A Column?
Swapping columns is a valuable technique for method development in HPLC, providing the flexibility to switch columns as required. To prevent the presence of air at the column entrance, it is advisable to slowly introduce solvent from the injector outlet line into the inlet fitting of the column. For effective re-equilibration of the column, we recommend flushing it with a minimum of six column volumes of the new solvent before injecting a sample. The initial injection should be disregarded since subsequent injections, starting from the second or third, typically exhibit reproducibility.
