Hydrogen is one of the themes at WoTS. On the special Hydrogen Square you can see a mobile hydrogen unit from TU Delft. Or visit the Hydrogen seminar on September 28, 2022.
And are you considering switching to hydrogen as a GC carrier gas? Then come visit the stand Da Vinci Laboratory Solutions for a demonstration of the DVLS3 Simply Smart Sensor; a hydrogen sensor that ensures safety while using hydrogen as a GC carrier gas.
The DVLS³ Simply, Smart Sensor is installed in the GC oven for continuous monitoring of hydrogen concentrations in the oven. The LCD screen of the external controller indicates the measured gas concentration. When the sensor detects a certain hydrogen concentration, usually defined by the user between 25% and 50% LEL (equal to 1% – 2% Vol. hydrogen), it will ensure the safety of the laboratory personnel in several ways:
- showing a red status on the dashboard
- sending an alarm message via email, text (SMS), Growl or Prowl
At Eastman Chemical in Middelburg they have equipped all GCs with a hydrogen sensor from Da Vinci. “A column break in a GC does not occur often, but if it does happen, the sensitive sensors immediately detect the hydrogen and shut down the GC via a not-ready signal, which then automatically switches to nitrogen,” describes Richard Burger, senior lab technician, the safe solution.
