Humidification and Gas Flow

Posted by Dr. Rachel Stansel on Thu, Aug 22, 2019 @ 09:20 AM

One of the most popular options for an Environics Gas Mixing or Dilution system is humidification. The Environics humidifier option or our stand-alone humidifier allows the operator to add specific RH levels to a blend of gases to simulate actual conditions in laboratory experiments or other cases where gas samples contain humidity. But what is humidification and how is this option applied for an Environics system?

A look at your Environics Calibration Documentation

Posted by Dr. Rachel Stansel on Fri, Jul 26, 2019 @ 07:38 AM

Today, let’s look at a key piece of documentation that you will receive one for each MFC in a new unit and with each recalibration, your calibration reports. We will also take a look at 2 optional items, incoming verification data and a certificate of calibration, and why you might want to request them. There is never an additional cost to obtain this data. You can click one each document to enlarge it below.

Gas Delivery Systems for Welding Applications

Posted by Dr. Rachel Stansel on Mon, Apr 01, 2019 @ 04:01 AM

Gas metal arc welding (GMAW) is a joining process that consumes shielding gas in significant volumes. Even hobbyists and other small-scale users of MIG welders require a robust gas delivery system to facilitate their welding process and protect the joint from reacting with atmospheric gases. Contamination of weld joints by ambient gases such as nitrogen (N2) can lead to metal embrittlement and porosity, which can ultimately contribute towards mechanical failure.

Ambient Calibration with Environics

Posted by Dr. Rachel Stansel on Tue, Mar 26, 2019 @ 11:35 AM

Monitoring the composition of ambient air is a vital process in maintaining the quality of the air we breathe. The World Health Organisation (WHO) has attributed millions of deaths per year to air pollution and inhalation of industrial particulates emitted by vehicles and industrial plants. New research has underlined the severity of the issue, suggesting that the health impacts associated with polluted air are more severe than previously believed. The European Heart Journal estimates that air pollution reduces the mean life expectancy in Europe by approximately 2.2 years[1].

Gas Flow Systems for Medical Devices

Posted by Dr. Rachel Stansel on Thu, Feb 28, 2019 @ 10:14 AM

Gas flow systems serve myriad purposes around the world. They are used to calibrate gas chromatographs (GC) in laboratory and analytical facilities and have been widely employed in the mixing, blending, and delivery of appropriate medical gas mixtures. Ground-breaking clinical research into the interaction between distinct gases and cellular behaviour has also benefits from the availability of ultra-high precision gas flow systems certified for medical use. This has supported analytical clinicians and researchers in various medical fields, from oncology to optometry.

MFCs for Hypoxia Training

Posted by Dr. Rachel Stansel on Thu, Feb 21, 2019 @ 09:11 AM

Thermal mass flow controllers (MFCs) are often used to control the flow of a gas species based on the dissipation of thermal energy. This is achieved by integrating a sensor tube into the flow system which is equipped with up and downstream temperature sensors. The gas absorbs heat as it enters the component and loses heat on its way out. MFCs are engineered to calculate the differential temperature in the tube and generate an electrical signal for additional instrumentation. This technology is central to numerous gas blending technologies and is broadly used in a range of application areas.

Performing Ozone Calibration with Environics

Posted by Dr. Rachel Stansel on Fri, Feb 15, 2019 @ 08:12 AM

Ozone (O3) is subcategorized into three primary groups; stratospheric, tropospheric, and artificially-manufactured ozone. Stratospheric ozone is a naturally-occurring substance that forms in the upper stratosphere, up to sixty miles above the earth’s surface. Ultraviolet (UV) rays cleave oxygen (O2) molecules into individual atoms, and when these free atoms bind to whole O2 molecules, ozone is formed. This is the desirable category of the gas that protects the earth’s surface from the most harmful radiation of the sun.

3 Common Applications of Gas Flow Systems

Posted by Dr. Rachel Stansel on Mon, Feb 11, 2019 @ 09:05 AM

Gas flow systems are extremely varied in terms of device architecture, functionality, and measurement accuracy. They include delivery, blender, divider, diluter, and myriad other instrument types responsible for generating or introducing a pre-mixed gas flow into another system.

The Importance of Ambient Air Quality Testing

Posted by Dr. Rachel Stansel on Fri, Dec 21, 2018 @ 08:21 AM

Ambient air quality testing is conducted to determine the gaseous or particulate concentration of air that may be released into the environment or breathed by humans. Dry air in the Earth’s atmosphere comprises a dynamic mixture of gases, primarily nitrogen (~78%) and oxygen (~21%). Smaller volumes of argon (~0.9%) and carbon dioxide (~0.04%) are also present alongside copious trace level gas species and various particulate matter.

Gas Mixtures for Food Packaging Applications

Posted by Dr. Rachel Stansel on Thu, Dec 06, 2018 @ 06:27 AM

Global transit capabilities enable the rapid transport of perishable goods across the world to be enjoyed by consumers far from their country of origin. This is a complicated process that requires storage conditions to be continuously monitored and maintained within tight degrees of tolerance. Livestock products must be constantly refrigerated to avoid spoiling, while fresh fruit and vegetables must be kept in strictly controlled atmospheres to limit the rates at which they metabolize oxygen (O2).
