Vac‑Chip and Ion Optics
The vac-chip interface samples the ions from the microspray source and transports the
sampled ions into the vacuum chambers of the VERITY 1910 MS Detector.
After passing through the vac-chip, ions pass through a series of ion optics: a tube lens,
exit lens, ion guide and inter-quadrupole lens. Ions exiting the vac-chip are focused into the
ionchip® using these ion optics.
ionchip
The ionchip is a micro-engineered quadrupole mass analyzer based on patented technology.
It functions like a conventional quadrupole mass analyzer, acting as a mass filter, separating
ions in order of their mass-to-charge (m/z) ratios. However, it is about one hundredth the
volume of a conventional quadrupole mass analyzer.
Vacuum System
The vacuum system consists of a vacuum chamber coupled to a split flow turbo-molecular
pump, which is backed by a diaphragm pump. The vac-chip interface is pumped by an
additional small diaphragm pump.
All of the vacuum pumps are integrated internally in the VERITY 1910 MS Detector so there
are no external, floor-standing pumps. This significantly reduces equipment noise, footprint,
and size. There are also no complications associated with rotary pumps, such as back
streaming of pump oil and the use of oil traps.
The vacuum system comprises three sections:
● The vac-chip interface
● The ion guide chamber
● The analytical chamber
The pressures in the VERITY 1910 MS Detector are monitored using Pirani gauges which
also act as high-voltage interlocks. These gauges turn off any high voltages if the pressure
readings in the chambers are above a set safety value.

Inspect Shipment

Upon receipt of the instrument, inspect the exterior of all shipping cartons. All cartons should
arrive unopened and undamaged. If examination reveals that damage has occurred during
shipment, notify the carrier, and Gilson immediately. Refer to Customer Service on page 12.
