The Challenges of Environmental Monitoring
12 Jan 2019Air, water and soil samples are extremely complex requiring high sensitivity and advanced data processing for trace level detection.. Additional challenges come with the need for remote monitoring stations requiring autonomous operation in harsh environments 24 hours a day, 7 days per week. The challenge increases even further when remote monitoring stations are in difficult to reach, isolated locations where servicing the instrument regularly is not an option. For these reasons, components and instrumentation must be reliable performing in a range of ambient conditions for long-term measurements spanning days, weeks or even months.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics. Find the best UV-Vis spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.UV-Visible-NIRUV-Visible-NIR spectroscopy is used to analyze a wide range of samples based on their absorption of ultraviolet, visible, and near-infrared light. It is commonly applied in chemical analysis, material science, and quality control. Browse our peer-reviewed product directory to find the best UV-Visible-NIR spectroscopy systems, compare products, check reviews, and get pricing directly from manufacturers.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Airborne PollutantsAirborne pollutants are particulates, biological molecules or other harmful materials that exist in the atmosphere. These pollutants are known to cause harm to health and the environment. Examples include persistent organic pollutants (POPs), carbon monoxide, sulfur oxides, and nitrogen oxides.
