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.
Top 6 Questions You Should Ask When Buying a Gas Generator
- 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 infrared spectroscopy operates best in the absence of carbon dioxide, so users will require a generator that creates CO2-free gas
- 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.
- 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.
- 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 the safety and supply of tanks.
- 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.
- What sorts of service agreements are available? Is training in self-maintenance sufficient, or are service representatives available?
