Nitrogen has low reactivity with other kinds of elements and chemicals and hence is an inert gas. Because of this characteristic, it is used in multiple analyses and experiments. It is commonly used in Liquid Chromatography-Mass Spectrometry (LC-MS), Evaporative Light Scattering Detectors and Sample Evaporation. Modern labs use a lot of gases for tests, but nitrogen is the one that is used the most.
Things to consider before choosing a lab gas generator
Length in business
When you decide on getting a laboratory generator for Nitrogen Desiccator Cabinets, consider the supplier’s history. Considerthe length of time that they have been active in the market. Many suppliers are fairly new in the market, not more than a year or two. Some entered the market as players in the tire inflation sector and now sell in the industrial market. Consider a company that operates only in the field of nitrogen gas generation and must have been in the business for at least half a decade. They have a good reputation and are best for your requirement.
Type of generator systems
There can be different types of nitrogen generation systems, but the best and most popular in a Multi-Chamber Desiccator Cabinets are PSA or pressure Swing Adsorption and Membrane systems. The supplier that you choose must offer these and must have sufficient knowledge about this. Also, the laboratory’s requirement for nitrogen is to be considered in deciding between the two technologies. PSA is good if the nitrogen air is needed to be 99.5% pure. If lower quality air is sufficient then Membrane technology will do.
Country of manufacture
Consider the country of manufacture for the generator that you need for the laboratory. Suppliers can import the generator from China, in which case it will not meet the North American standards.
Fluctuation in demand
Deliberate if the demand increases then will you need to purchase a new generator. Find out if the generator is modular or expandable in case demand increases in the future. In some nitrogen generators, the production can be increased by adding another module. While choosing the generator, make sure it is a long-term investment.
You need to consider if the generator seller is familiar with the industry or not. A supplier must know what is required. For example, in food industries, a sterile gas filter is required. If you buy from an inexperienced seller he will not be able to guide you in the correct practices.
Cost is one of the main reasons to consider when you are buying a nitrogen gas generator. Most industries buy the gas directly. But if you can produce the gas at much cheaper rates in your own laboratory then you can buy a generator.
Buying gas directly instead of producing in-house has its disadvantages. Things like stock taking, timely delivery and safety while changing cylinders have to be considered. If you don’t want to do all of this, it is better to install a generator for in-house production
