How to Safely Use Hydrogen as a GC Carrier Gas?

To address the safety concerns related to the use of Hydrogen as a carrier gas is installing the DVLS³ Simply, Smart Sensor; a sensor that constantly monitors the hydrogen concentration in a GC oven and automatically switches to an inert gas in case of an increase in the hydrogen concentration. Furthermore it will ensure the safety of the laboratory staff by transmitting several alarms.

Send alerts to the staff

The DVLS³ Simply, Smart Sensor is installed in the GC oven for continuous monitoring of the hydrogen concentration in the oven compartment. The LCD screen of the external controller displays the real time hydrogen concentration

(Figure 2).

If the hydrogen concentration reaches the user defined level, typically between 25% and 50% LEL, the sensor will alert the laboratory staff by:

• Flashing of the LCD controller screen
• Transmitting an acoustic alarm
• Showing a red status on the software dashboard (Figure 3)
• Sending an alarm message by e-mail, text (SMS), Growl or Prowl.

The sensor controller will automatically switch the carrier gas to an inert gas and send a stop signal to the GC.

Manage alarm settings

The new optional DVLS³ Sensor software makes it easy to define and control settings such as:

• Managing the user access level and their contact details to define the alarm messages by e-mail, text (SMS), prowl or growl
• Setting up the system configuration either manually or automatically to enter the sensor hardware specifications
• Creating an audit trail to check the records of the reported alarms and changes in any settings

Detect a Hydrogen leak and more

Due to the unique design of the DVLS³ Simply, Smart Sensor you can combine up to four sensors in one controller. For example use four sensors for several GC’s or connect several sensors to one GC. The sensor is compatible with all GC brands.

Next to the hydrogen leak detection Da Vinci Laboratory Solutions offers multiple sensors dedicated to the detection of:

• Hydrogen
• Temperature
• Barometric Pressure
• Level (liquid) weight.

The versatile multi sensor offers GC labs a safe solution to change an expensive GC carrier gas such as Helium to Hydrogen. Listen to the recorded webinar on how to detect the hydrogen leaks in a GC systems using the DVLS³ Simply, Smart Sensor.
