The Agilent 5973 Network Diffusion Pump EI MSD (G2577A) comes from a family of Mass Selective Detectors (MSDs) optimally designed for use with the industry-leading 6890 Plus Series Gas Chromatograph as capillary gas chromatography detectors.

The 5973 MSD is a compact (occupying less than 0.2 m2 on a benchtop) unit that requires no cooling water or compressed air and operates on 120 VAC or 200–240 VAC. Each instrument includes a short GC interface (< 20 cm), an independently heated electron impact ion source, a metalized gold quadrupole mass filter, an electronics module, LAN communications, and a long-life off-axis HED (high-energy dynode) detector with a replaceable snap-in horn.

5973 Network MSDs offer true classical EI (electron impact ionization) spectra with the standard EI source. Chemical ionization (CI) operation is available with the optional PCI/NCI (positive/negative chemical ionization) ion source.
