Desorption Electrospray Ionization: Achieving Rapid Sampling Rates
- Solution used
- PSRF-100 radio-frequency power supply; two RF-only quadrupole ion guides
The Stanford team used an Ardara PSRF-100 supply to drive two RF-only quadrupole guides at 1.46 MHz in a rapid desorption electrospray ionization sampling system. The guides transported ions through a configuration designed to reduce carryover between sequential samples. The instrument resolved alternating analytes at up to 80 samples per second and a single analyte at 50 samples per second. This paper is an early public example of an Ardara RF supply supporting high-speed ambient ionization and automated sample throughput.

Chip-Scale Quadrupole Mass Filters for Portable Mass Spectrometry
- Solution used
- Slim-Line electron-impact ionizer; filament and ion-optics supplies
MIT researchers used an Ardara Slim-Line electron-impact ionizer together with Ardara filament and ion-optics power supplies to characterize a microfabricated quadrupole mass filter. The experimental platform demonstrated a mass range to 650 amu and resolving power of about 90 at mass 28 in the second stability region. The application shows Ardara components serving as a dependable source and control stack for evaluating compact, MEMS-based mass analyzers intended for portable instruments. The acknowledgments cite Ardara technical guidance; there was no Ardara coauthor.

A Chemical Ionization Residual Gas Analyzer for the Sensitive Detection of Atmospheric Trace Gases
- Solution used
- Multichannel DC supply for ion optics, digitally controlled through a DAQ
A multichannel Ardara DC supply powered the ion optics in a compact chemical-ionization residual gas analyzer and was digitally controlled through a National Instruments DAQ. The field-deployable instrument was built for less than $50,000, achieved a 20-second, 3-sigma detection limit of 18 ppt for deuterated dimethyl sulfide, and completed three days of ambient sampling. This case broadens the public application record from laboratory mass spectrometry to lower-cost atmospheric trace-gas monitoring.

Low-Cost, Compact Quadrupole Mass Filters with Unity Mass Resolution via Ceramic Resin Vat Photopolymerization
- Solution used
- Slim-Line ionizer, continuous-dynode electron multiplier, and preamplifier
The MIT-Ardara collaboration evaluated additively manufactured ceramic quadrupole mass filters using an Ardara Slim-Line source and Ardara detection electronics. The printed filter resolved a 131 Da peak with 0.50 Da full width at half maximum, corresponding to about 260 resolving power, while covering a 250 Da mass range and reaching 0.13 mA/Torr sensitivity. The paper demonstrates Ardara equipment enabling reproducible validation of a lower-cost manufacturing route for compact mass analyzers.

Development of a Glow-Discharge Ion-Trap Instrument for Measuring Effective Radiative-Association Rate Coefficients
- Solution used
- Custom glow-discharge ion source, RF-only rectilinear guide with asymptotic rods, deflectors, quadrupole mass filter, detectors, and linear ion trap
The instrument combined a custom Ardara-designed glow-discharge source with ion transport, mass selection, detection, and trapping subsystems for low-temperature ion chemistry. Its first pressure-dependent study examined Ag+ reacting with O2 and placed a lower limit of 1 x 10^-15 cubic centimeters per molecule per second on the effective radiative-association rate coefficient. This coauthored work documents Ardara's role in building a complete experimental chain for a specialized reaction-kinetics problem.
