Multi-gas analyzers are a very important part of ambient monitoring, where low-level concentrations of certain species can have a dramatic impact on air quality. They are deployed across a wide spectrum of applications from environmental monitoring to workplace health and safety. However, these analyzers are subject to interference from numerous factors that can cause inaccuracies. Here we will outline the importance of multi-gas calibration as well as discussing the benefits and key features of multi-gas calibration devices.

Significance of Multi-Gas Detection

Many gases will go undetected without the use of specific electrochemical or optical gas detection equipment. This can be lethal in both indoor and outdoor spaces, with poor ambient air quality contributing to a growing number of fatalities year on year. Hence the effective use of multi-gas analyzers can legitimately save lives, by providing data-driven insights to environmental scientists and process controllers.

Importance of Multi-Gas Calibration

Multi-gas calibration is a crucial part of routine equipment maintenance and is a critical part of ensuring worker safety in hazardous environments. Both fixed and portable analyzers may succumb to chemical degradation and/or unavoidable calibration drift due to gradual electronic deterioration. Multi-gas calibration can help to correct drifting and ensure that analyzers are working at optimal levels.

Multi-gas calibration is necessary as analyzers are frequently subject to extreme environmental conditions that can have an adverse effect on performance. This includes humidity, temperature, airborne particles and vapors, high concentrations of target gases and sensor poisons and inhibitors.

It is also important to carry out multi-gas calibration following a detector being dropped on a hard surface, exposure to water, or being handled frequently enough to have an impact on the on the electronic components.

Key Features of Multi-Gas Calibration Instruments

It is vital that multi-gas calibration devices are completely accurate and the Environics® Series 6100 Computerized Multi-Gas Calibration System is exactly that. It is an innovative computer-controlled instrument which offers dynamic multi-gas calibration of ambient air analyzers. The Series 6100 completes zero, precision, multi-point, and span calibrations automatically employing NO, NO2, SO2, CO, 03, hydrocarbons and many more gases of note. The instrument is also able to perform multi-gas calibration remotely, employing contact closures or the RS-232 serial data interface.

The device employs interactive software which is simple to use with plain language. This means it is easier and less time-consuming to train technicians in multi-gas calibration and results in a very small margin of error. The requirement of manual computation is eliminated due to automatic calculation of dilution and span gas flows based on the commanded concentration; this also means that transition from point to point is much quicker.

The mass flow controller calibration data is internally stored, this allows for increased accuracy and simplified multi-gas calibration in the field. Environics has multiple products available for multi-gas calibration, ensuring that the right instrument can be selected for a project.
