On-Site Hydrogen Gas Lab Server Application for the Operation of GC Units

On-site gas generators are gaining traction among Gas Chromatography (GC) professionals for the efficient and reliable supply of hydrogen gas. The installation of a single large hydrogen generator as a Lab Server enables a laboratory to receive a continuous supply of pure carrier gas and Flame Ionization Detector (FID) fuel from a controlled central source.

Hydrogen as an Alternative Carrier Gas

The scarcity of helium forces GC professionals to seek out an alternative carrier gas. Hydrogen shows promise as an alternative carrier gas in terms of cost and efficiency, but holds the potential threat of fire and explosion when stored in pressurized form. Hence, the use of a hydrogen generator is a smart solution that ensures both safety and efficiency.

Proton OnSite’s Innovative Solution

For professionals running tens or hundreds of GC units and FIDs, deploying several gas generators around the laboratory is a cost-intensive process. To address this situation, Proton OnSite has created a ‘lab server’ system capable of accommodating up to 200 GC systems.

Hence, a Proton OnSite hydrogen gas lab server would be adequate for a lab running up to 200 GCs and FIDs. The specifications of a Proton OnSite hydrogen gas lab server are summarized in Table 1.

Table 1. Specifications for a Hydrogen Gas Laboratory Gas Generator

Flow Rate 4.8 – 18.8 LPM
Pressure 0 – 200 PSIG
Water DI Water ASTM Type II (4)
Dimensions 31” x 38” x 42”
Power 205-240 VAC, 50 or 60 Hz
Environmetal Conditions 40°F – 90°F, < 90 percent RH, nonclassified space

Proton OnSite offers its hydrogen gas lab server in three basic versions that yield a wide choice of gas flow rates to the laboratory manager to satisfy the hydrogen gas demand in the lab.

It is necessary to place the hydrogen gas lab server on a flat surface in a well-ventilated location.

The extremely low density of hydrogen enables use of the generator at a location far from the point of use without the requirement of large diameter piping.

Sample plumbing schematic for a Lab Server is depicted in Figure 1.

Advantages of Proton OnSite Hydrogen Gas Lab Server

A single hydrogen gas lab server can supply hydrogen gas to as many as 200 GC units accompanied by an FID. In addition, the hydrogen generator’s patented ‘load following’ gas flow control allows for monitoring and controlling all individual GC gas supplies for purity, flow and pressure.

The requirement to store hydrogen in the lab can be avoided through the installation of the hydrogen gas lab server. The capacity of a hydrogen gas lab server is outlined in Table 2.

Table 2. Outline of a Hydrogen Gas Lab Server’s capacity

Carrier Gas FID Gas Quantity Lab Server Model
30-40cc/min, 40-160 PSIG 200cc/min 2 - 3 G600P
8 - 25 G4800
26 – 100 S20
101 – 200

One standard hydrogen cylinder with 6300L capacity would normally supply gas to 25 GC units for roughly two days. Its explosive potential is the equivalent of 35lbs of TNT. A hydrogen gas lab server stores less than 1L of gas, even when it is running at its optimum flow capacity.
