Moreover, using gas mixers can lead to a range of benefits that ultimately reduce costs and increase profitability.
This article explores the reasons why gas mixers are a more cost-effective solution for GC calibration than gas cylinders, as well as the other advantages they offer.
What is GC Calibration?
Gas chromatography (GC) is a highly effective analytical technique that enables the separation and analysis of volatile compounds in mixtures.
This method is widely used to identify chemical compounds and determine their presence or absence in a range of applications, such as quality control, research and development, and safety assessments for both solid, liquid, and gas samples.
To conduct GC analysis, a specialized GC instrument is used; however, over time, this equipment can drift and produce unreliable readings if not calibrated. GC calibration is, therefore, critical to ensuring the accuracy, precision, and repeatability of results.
Why are Gas Mixers More Cost-Effective than Cylinders in GC Calibration?
Various advanced technologies are available to detect, quantify, and analyze different gases in diverse applications. These instruments, ranging from gas detectors and analyzers to environmental monitors, all require calibration to ensure they generate accurate results regarding the presence of gases in a given area.
To accomplish accurate calibration of gas detectors and other gas instruments, gas mixers are an efficient and cost-effective method that provides more benefits than using gas cylinders.
Gas mixers are cost-effective for several reasons. Pure gases are cheaper to purchase than pre-mixed cylinders of gas, and because it is possible to hold more volumes of pure gas, there are fewer rental and delivery costs than cylinders.
Gas cylinders contain pre-mixed gases of a known concentration, but this may not be suitable for every application. Any mistake with the mixture can result in issues such as a new delivery, waiting times, and additional expenses.
Employing a gas mixer allows for a wide range of gas mixtures for limitless applications. They require less space than a gas cylinder and can be utilized flexibly in laboratories.
Therefore, when gas chromatography (GC) is necessary, gas mixers can create the exact mixture required in-house, eliminating lengthy waiting times.
To summarize, the key benefits of using gas mixers include the following:
- Ease of set up for use with any gasses
- Control over mixtures and processes
- High quality, accuracy, and repeatability
- Lower costs
Mixers are highly cost-effective and dependable instruments that can be utilized to create precise gas mixtures tailored to meet specific calibration requirements.
These mixers are available in various configurations, providing options for diverse industries and applications. In addition, manufacturers such as Environics can design and build customized machines.
