Triode Style and Mini Bayard-Alpert Ion Gauge Tubes

Triode style (342003)

These 8138/29D20 Triode style and Mini Bayard Alpert Style hot ionization gauge tubes measure a wide vacuum range. Smaller than standard glass Bayard-Alpert gauges, they are ideal for use in analytical instrumentation. Accidental exposure to atmosphere a normal operating temperatures will not damage the gauge because of the use of the thoria coated iridium filaments.

SIS Newsletter

Covers SIS products, services, promotions, news, and other mass spectrometer related information.

28 Aug 2013: Nanoliter Dispensing Devices can be used to place media on the MALDI plates for MALDI/TOF instruments, but the most exciting ability of this device is to collimate droplets directly into the ion source like electrospray (ESI), the unique concept being that nearly 100% of the droplets go directly into the source versus <1% from ESI, giving a huge increase in sensitivity. We believe this could be the next big advance in LC/MS sources. [NEW]
