As the first in the world, NEO Monitors has developed a solution for measuring hydrogen in-situ using traditional infrared (IR) tunable-diode-laser (TDLAS) absorption spectroscopy.

The underlying technology has already been used successfully for a manifold of industrial applications. Launched at Achema, the LaserGasTM II SP H2, opens up for new opportunities in process control with exceptional response time of less than 2 s, says Ketil Gorm Paulsen, CEO of Neo Monitor. Not only that; the cost of monitoring will be significantly reduced compared to traditional monitoring methods. LaserGasTM II SP H2 is accompanied by LaserGasTM II MP H2, an extractive multi-pass solution for applications with higher demands on sensitivity or wherever an in-situ solution is not feasible.

“We have been working towards this moment for years, building brick by brick. It has been perceived as impossible, but we’ve done it anyway,” Paulson says.

“The H2 molecule has for a long time been considered as non-absorbing in the IR region. This is de facto incorrect and by redesigning our analyzers we have achieved an unprecedented sensitivity down to the tiny absorption levels required to monitor H2. Our new analyzer is the perfect solution for many applications and opens up for better process control in reactive, toxic and corrosive gas streams,” he says. The new solution will fit in any chemical plant or petroleum refinery, anywhere in the world. The oil-and-gas industry, and other chemical production will benefit from realtime measurements of H2 levels.

LaserGasTM II SP and MP H2 provides contactless and continuous monitoring of H2 concentrations with a response times of less than 2 or 20 seconds, respectively. The solution maintains all advantages of the well-proven, trusted and flexible LaserGasTM technology. LaserGasTM II SP and MP H2 can detect leakages and increase the efficiency of process controls and increase security. “With 25% of our staff working in R&D, we are innovators,” says Paulson. “It’s not magic, it’s teamwork,” he says.
