Definition
Gas calibration is done with pure air and standard calibration gas, at a high concentration range of 1-10 ppm and flow rate of 0.5 L/min. Such tests are repeated several times to ensure the highest level of data quality. The readings from the device are compared with the known concentration of the reference gas and the necessary corrections are made. Only those air quality monitors with benchmark performance in precision and accuracy are declared passed from the test to be deployed in the field.
Definition
A gateway is a network device or software application that serves as an intermediary or bridge between two or more different networks, enabling them to communicate and exchange data. Gateways play a crucial role in facilitating communication between networks with different protocols, architectures, or technologies, ensuring that data can flow smoothly and securely from one network to another. It includes characteristics like Protocol transmission, Interconnection, Security, Data routing, Network management, integration, Cloud connectivity and application layer services. Gateways are used in a wide range of networking scenarios, including in homes and businesses to connect to the internet, in industrial settings to link different machines and sensors, and in the IoT to facilitate communication between devices and cloud platforms. They are essential for ensuring that data can flow seamlessly between diverse networks, regardless of their underlying technologies or configurations.
Definition
GC-MS stands for Gas Chromatography-Mass Spectrometry. It is a powerful analytical technique used in chemistry and biochemistry to identify and quantify the chemical composition of complex mixtures of substances. GC-MS combines two separate analytical techniques, gas chromatography (GC) and mass spectrometry (MS), into a single instrument.
Definition
Greenhouse gases (GHGs) are gases present in the Earth’s atmosphere that have the property of trapping heat (infrared radiation) from the sun and preventing it from escaping back into space. This process, known as the greenhouse effect, is essential for maintaining the planet’s temperature within a range that is suitable for life. However, an excess of greenhouse gases can enhance this effect, leading to global warming and climate change. (example – Water vapor (H2O), Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Ozone (O3), Chlorofluorocarbons (CFCs and HCFCs), Hydrofluorocarbons (HFCs), Perfluorocarbons (CF4, C2F6, etc.), SF6, and NF3)
Definition
GPS stands for “Global Positioning System.” It is a satellite-based navigation system that allows users to determine their precise geographic location and track their movement with a high degree of accuracy anywhere on or near the Earth’s surface. GPS technology is widely used for various applications, including navigation, mapping, surveying, and location-based services.
