the notch at the bottom of the liquid head, although this sign may not be
present if the solvent leak evaporates quickly.
Seal wear is accelerated under adverse conditions, such as pumping at high
flow rates or pressures, using aggressive or aqueous solutions, or dirty or
contaminated mobile phase. Moderate operation (low flow, low pressure,
organic solutions, and fresh clean HPLC-grade mobile phases) will result in
longer seal life. However, every seal will eventually need replacing. Software in
the Agilent SD-1 Pump allows you to both check the seal wear and to log when
the seals are changed. Your pump uses either a standard liquid head or a
washing liquid head.
