Pfeiffer 2G Filament Frequently Asked Questions

1. Which mass spectrometers or leak detectors use the Pfeiffer 2G filament?

The Pfeiffer 2G filament is specifically designed for Pfeiffer Series 2 helium leak detectors (142, 142D, 182T, 182TD) and is compatible with select Alcatel models.

2. Why choose yttria-coated iridium for Pfeiffer ion source filaments?

Yttria-coated iridium offers superior high-temperature stability and electron emission properties, significantly extending filament service life.

3. How to determine when a helium leak detector filament needs replacement?

Decreased sensitivity, increased background noise, or complete detection failure indicate potential filament degradation requiring Pfeiffer 2G replacement.

4. Are Alcatel filaments interchangeable with Pfeiffer filaments?

Some models are cross-compatible, but always verify specific model compatibility through technical documentation or supplier consultation.

5. What precautions should be taken when replacing Pfeiffer 2G filaments?

Power off and release vacuum

Use cleanroom gloves

Ensure precise installation

Recalibrate instrument post-installation

6. What is the typical service life of yttria-coated iridium filaments?

Normal operation typically provides 5,000+ hours of service, depending on operating environment and usage frequency.

7. Do Series 2 repair kits include installation tools?

Standard packaging doesn't include specialized tools - use manufacturer-recommended tools for replacement.

8. What calibration is required after mass spectrometer filament replacement?

Post-replacement procedures should include:

Electron emission testing

Sensitivity calibration

Background checks
to ensure proper instrument performance.

9. How should unused Pfeiffer filaments be stored?

Store in dry, particle-free environments using proper packaging, avoiding direct hand contact with filament surfaces.
