Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.
Common air monitoring applications include:
Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
Asbestos sampling and analysis
Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.
Our purpose built environmental laboratory provides accurate and efficient analysis, specialising in the determination of gaseous pollutant concentrations. Other processes can also be performed to meet the specific needs of our customers.
A wide variety of products that are used in our indoor environments may emit harmful substances, raising health and safety concerns in homes, offices, public places and vehicles. There is increasing demand to reduce VOC emissions from indoor sources, backed by European legislation. REACH regulation is a European initiative for the Registration, Evaluation, Authorisation and Restriction of Chemical Substances. It was implemented to protect human health and the environment from harmful emissions of chemicals into...
Within the field of gas analysis much time is spent looking at the accuracy and uncertainty in the detection technique. However, without appropriate sample handling, what you are measuring could potentially bear little or no relation to your original sample.
Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.
Many occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.
CO (carbon monoxide) and CO2 (carbon dioxide) are generally measured to ensure process control. CO2 is the desired product and CO is undesired in combustion since it will explode in high enough concentrations. CO2 and CO concentrations can also be used to determine other process-specific efficiencies. Continuous emissions monitoring equipment that can be calibrated as a CO and CO2 analyzer is thereby essential for process control.
Engine and vehicle emissions testing involves complex routines and audit regimes to meet with exacting modern legislation. The methods for measuring gases are also prescribed by the relevant authority and so you might imagine that the equipment for emissions testing is all the same. Signal take a different approach to our competitors. By designing bespoke systems from a selection of standard modules, we supply all the equipment and features you require, but nothing that you don`t. This makes our systems the...
OPSIS EEx Zone 1 and 2 certified monitoring equipment meets the demands for monitoring in harsh areas with a high amount of corrosive gaseous compounds. OPSIS offers two monitoring solutions, TDL (Tuneable Laser Diode) technology with ER060L-EEx emitter and receiver set, for harsh installations, and OPSIS O2000 oxygen monitor. The most suitable technique is used for the application at hand.
Gas Detection is our core business, whether portable, colormetric, fixed systems or Hazmat. We do more than get you the equipment you need--we also help you select it, calibrate it, service it and maintain it. Our technicians, our sales reps and top management can speak with authority on the capabilities of our equipment and match it to your specific application. And we are the champions of the one-of-a-kind solution, because we have the know-how and the right tools.
The Cleanroom is a combined laboratory chemical, mechanical and / or electronic whose main characteristic is the presence of very pure air, that is a very low content of fine dust in suspension. In the process of semiconductor production, the airborne particles (micro-powder) go to irreparably damage the micro-photoetched that form the chip, creating an electronic circuit defective, and then discarded. This process has forced the improvement of industrial production environments, removing particles from the air,...
SF6 (sulphur hexafluoride ) or air is used as an insulation gas in circuit breakers . Excess moisture in these gases causes arcing, which can trip the circuit breaker and cut off power to the distribution network. More seriously, such arcing can lead to physical damage of equipment and, on occasion, death of plant operatives (please ask for our case study on circuit breakers).

Abstract : A preliminary evaluation of techniques of sampling and gas chromatographic analysis for low levels of sulfur hexafluoride was conducted to determine the most feasible method for available equipment....
NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.
Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.
Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application....
Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have...
