Quality Calibration Gases Categories

While preparing calibration gas mixtures, two types of measurements are made – • volumetric or gravimetric measurement - measuring what goes into the cylinder; requires a calibrated pressure or flow device (volumetric) or a calibrated balance (gravimetric) • measurement based on analysis - measuring what comes out of the cylinder; requires a gas analyzer and several reference gas mixtures High quality gas mixtures are manufactured gravimetrically and analyzed with an accredited process, outlined on the cylinder certificate. Specialty gas mixtures are also classified into one of the following categories, based on how they are made, tested, analyzed, or certified. Traceable Gas Mixtures Traceable mixtures are those gas mixtures that have been manufactured using traceable weights and measures. In other words, regardless of the method is used to manufacture the mixture, the instrumentation had undergone a traceable calibration.  Certified Gas Mixtures Certified mixtures are the ones th

Top Reasons Why Calibration Gases are Vital for Ship Safety

Is your ship compliant with emissions limits? There are several Government, international and other regulations that require passenger and commercial ships to comply with standards to protect passengers, cargo, and the vessel from hazardous gases.  Compliance with such regulation requires the use of gas detecting instruments. To make sure your gas detection equipment is functioning properly, you need accurate calibration using high-quality gases. A ship can fall into different categories. Check with your country’s laws to determine the category your propulsion device falls into, and the regulations that apply to your engine type. To ensure compliance with safety and environmental regulations means, you need to carry out mandatory testing, for which you require calibration gases. Most toxic or combustible gases and hazardous substances are odorless, and workers or operators may not be able to detect a problem until it’s too late. So, you need gas detectors to catch potential dangers. An

Calibration Gases 101

  Calibration gases are specialty gas. They are different gas mixes, and are used to calibrate analytical instruments, such as gas analyzers and gas detectors. This is why calibration gases need to have a precise composition, for example, zero gas or span gas. Calibration gases must also be traceable to a national or international standard and supplied carefully. Specialty Gases Uses In addition to being used as calibration gases, specialty gases have a number of applications, and that requires different types of specialty gas equipment.   Specialty gases of up to 99.995% purity are used across a wide range of industries, from pharmaceuticals and electronics to petrochemicals and aeronautics. How to select Specialty Gas Suppliers? It's important to select your specialty or calibration gas supplier carefully. This would include high accuracy and quality of the gases. It's also important to find a supplier who can assure you that their customer service representatives a
