Agilent IDP-3 Scroll Dry Vacuum Pump

Overview

The Agilent IDP-3 Scroll Dry Vacuum Pump is an engineered solution for clean, reliable, and maintenance-efficient vacuum generation in analytical laboratories and OEM instrument integration environments. Based on proven scroll compression technology, the IDP-3 operates without lubricating oil—eliminating hydrocarbon backstreaming, oil vapor contamination, and associated downtime from oil changes or filter replacements. Its hermetically sealed motor and fully isolated bearing assembly ensure that no internal components contact the vacuum path, thereby guaranteeing long-term operational stability and consistent ultimate vacuum performance down to 0.33 mbar (absolute). Designed specifically for compatibility with mass spectrometry systems—including Agilent single-quadrupole GC/MS platforms—the IDP-3 delivers precise, repeatable vacuum conditions essential for ion source pressure control, detector sensitivity, and spectral fidelity. Its compact footprint (358 × 140 × 127 mm) and lightweight construction (10.5 kg) enable seamless integration into space-constrained analytical instruments, leak detection stations, and helium recovery modules.

Key Features

• Oil-free scroll mechanism ensures contaminant-free vacuum—critical for GC/MS, residual gas analysis (RGA), and surface science applications.
• Hermetic motor and isolated bearing architecture prevent vacuum-side exposure, extending service life and reducing failure risk.
• Single-stage scroll design enables rapid pump-down to base pressure with minimal thermal drift and low vibration output (< 5 µm/s RMS).
• Acoustically optimized housing achieves < 48 dB(A) sound pressure level at 1 m—supporting quiet laboratory environments per ISO 7779 standards.
• Integrated digital timer allows programmable duty-cycle control, enhancing energy efficiency and pump longevity during intermittent operation.
• Modular service design permits full maintenance—including scroll replacement and seal inspection—in under 15 minutes using standard hand tools.
• Optional 24 VDC motor variant supports regulated speed control via external analog or PWM signal—ideal for feedback-controlled vacuum loops in automated systems.

Sample Compatibility & Compliance

The IDP-3 is compatible with inert and mildly reactive gases typical in analytical workflows (e.g., He, N₂, Ar, air, and common carrier gases used in GC and vacuum manifold systems). It is not rated for condensable vapors, corrosive gases (e.g., Cl₂, NH₃, HF), or particulate-laden streams without upstream filtration. All units comply with IEC 61000-6-3 (EMC emission limits), IEC 61000-6-2 (immunity), UL 61010-1 (safety for laboratory equipment), and EU RoHS Directive 2011/65/EU. The pump meets CE marking requirements for the European Economic Area and is validated for use in GLP-compliant laboratories where audit-trail-capable vacuum system logs are maintained via external data acquisition interfaces.

Software & Data Management

While the IDP-3 operates as a standalone unit without embedded firmware or network connectivity, its timer function supports basic operational logging when paired with external PLCs or SCADA systems. For integration into Agilent GC/MS platforms (e.g., 5977B MSD), the pump interfaces seamlessly with Agilent MassHunter software via hardware-triggered status signals (e.g., “pump ready” and “vacuum achieved”). When deployed in regulated environments subject to FDA 21 CFR Part 11, users may implement electronic record-keeping of pump runtime, cycle counts, and maintenance events through third-party LIMS or ELN systems—leveraging the pump’s TTL-compatible timer output and mechanical relay contacts.

Applications

• Primary roughing pump for benchtop mass spectrometers (e.g., Agilent G6696A GC/MS kit, Thermo Fisher ISQ series).
• Vacuum backing for turbomolecular pumps in UHV pre-vacuum stages.
• Process vacuum source in helium leak detectors (e.g., Inficon LeakChecker series) and vacuum integrity testers.
• OEM integration into portable Raman spectrometers, residual gas analyzers, and plasma etch monitoring tools.
• Controlled-atmosphere sample preparation chambers requiring stable, oil-free vacuum below 1 mbar.

FAQ

Is the IDP-3 suitable for continuous-duty operation?
Yes—the IDP-3 is rated for indefinite continuous operation at ambient temperatures up to 40 °C and relative humidity ≤ 80% non-condensing, provided adequate ventilation is maintained around the rear cooling vents.
Does the IDP-3 require a dedicated exhaust line or venting to atmosphere?
No—exhaust is atmospheric and non-hazardous; however, routing exhaust away from sensitive instrumentation or operator breathing zones is recommended per ISO 14644 cleanroom guidelines.
Can the IDP-3 be used with aggressive process gases?
Not without additional protection—corrosive, condensable, or chemically reactive gases must be removed upstream using cold traps, scrubbers, or chemical filters to preserve scroll integrity and warranty coverage.
What accessories are required for GC/MS integration?
The G6696A kit includes all necessary components: IDP-3 pump, stainless steel front-end hose, Swagelok fittings, hose clamps, mounting brackets, and installation documentation. A separate power cord (IEC C13 type) must be sourced locally.
How often does preventive maintenance need to be performed?
Agilent recommends visual inspection every 6 months and scroll replacement every 12,000 operating hours or 36 months—whichever occurs first—under typical lab usage conditions.
