Distinguishing between polyamide microplastics and natural polyamide
17 Feb 2022In this application note, an Agilent 8700 Laser Direct Infrared (LDIR) chemical imaging system was used to successfully discriminate between natural and synthetic polyamides. The instrument utilized a large field of view camera to obtain an entire view of the sample and a microscope-grade objective to capture high magnification visual images.

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR 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.PolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.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.Infrared Imaging
