Why Hydrogen?

• The lightest gas of all• Lowest viscosity of all gases (easy to fill,

evacuate and dissipate) • Low background (0.5 ppm)

• Environmentally friendly, sustainable

• Much cheaper than helium

• Non flammable (when diluted 5% in N2)

• Non toxic - non corrosive

Hydrogen Instrument advantages

• Simple and robust for industrial use• No vacuum pumping

• No need to draw sample into the detector

• Flexible design

• Easy to calibrate

• No maintenance

When simple methods are not good enough and mass-specs are too complicated...

When to use Hydrogen?

Hydrogen vs Pressure Decay

The Hydrogen Method... • can locate leaks• is independent of variations in

temperature• is perfect for testing soft objects• is independent of size of test

objects’ internal volume• has a higher sensitivity

(Pressure Decay from 10-2 ml/s Hydrogen Method from 5x10-7 ml/s)

Hydrogen vs Helium

Hydrogen vs Helium

Locating leaks in...• Buried and ducted cables

• Aerial cables

• Pipes and ducts

• In-house heating pipes

Outside Plant

Industry - instruments

• Manual Leak Location• Manual & Automatic

Leak Testing

Industry – Leak Test Systems

• Sniffer clamp test• Accumulation chamber

test (integral test)• Scanning

• Pump Method

Sniffer clamp

Example: Clamp over welded joint
