AXP-MS Auxilliary Pump for MS

The AXP-MS single-piston pump uses a digital stepper drive and rapid refill to deliver precise and accurate flow. An internal transducer provides pressure display and monitoring capability. The AXP-MS is a high-quality auxiliary pump for MS support or general metering applications. It is also useful as a flow source when other pumping is not available or would be inconvenient.

Features:

  • Wide flow range
  • Internal pulse damper
  • Fully IC and biocompatible
  • Positive seal-washing standard to extend seal life by removing salts and wetting the seal
  • Flexible, advanced Chromeleon control (version 6.8 or later)
  • Integrated injection valve with a purge/priming port for precise flow or loop injections

Multiple Uses:

  • Supply of cone wash solvents to keep the entrance orifice of the MSQ free of salt and matrix buildup, thereby increasing the time between required maintenance cleaning of the MSQ
  • Postcolumn addition pump for introducing organic additives or acid/base modifiers to the eluent stream, or reagents for the derivatization of analytes after chromatographic separation.
