Are You in the Market for a Gas Generator?

By

In many laboratories, gas generators are quickly replacing traditional tanks offering greater flexibility, convenience, safety and cost-effectiveness. Gas generators offer the ability to produce on-demand supply and specialty blends of highly pure gases for various applications.

Types of gas generators currently used by survey respondents:

Hydrogen 38%
Nitrogen 30%
Zero Air 18%
Calibration 5%
Purge 5%
TOC 2%

Gas generator applications reported by survey respondents:

Gas Chromatography with mass spectrometric detection 31%
Gas Chromatography with flame ionization detection 28%
High performance liquid chromatography 15%
Other (e.g., LC-MS, SAA) 10%
TOC analysis 6%
Fourier transform infrared spectroscopy 6%
Inductively coupled plasma systems 2%
Nuclear resonance spectroscopy 1%

Over 55% of respondents currently using a gas generator plan on purchasing a new or additional gas generator in the next year for the following reasons:

Cheaper than gas cylinders
Switching from helium to hydrogen
Increased safety
Upgrading old system
Starting a new lab process
Building/renovating lab
QA/QC
Other

Top 6 Questions You Should Ask When Buying a Gas Generator

1. What is your application? As the range of available gas generators continues to expand, consider what it will be used for. For example, Fourier transform IR spectroscopy operates best in the absence of carbon dioxide so users will require a generator that creates CO2-free gas.

2. Do you require high quality gas? In many cases gas generators can produce a superior product both in purity and consistency without the risk of contamination during gas-line changing.

3. What volume of gas do you require? Many instruments now require higher volumes of gas. If your space is small, or you expect your needs to increase over time you may wish to consider a gas generator which will take up much less space than storing tanks of gas.

4. Are long-term cost savings important to your project? Beyond convenience, gas generators save on shipping costs, time-related costs for changing tanks, and managerial costs for managing safety and supply of tanks.

5. Is noise a factor in your lab? Noise can be both bothersome and present a real health concern for those exposed. If low-noise is desirable, consider a gas generator with detachable or low-noise compressors.

6. What sorts of service agreements are available? Is training in self-maintenance sufficient, or are service representatives available?
