The Radium Delayed Coincidence Counter (RaDeCC) is an alpha scintillation counter used to measure radium isotopes in environmental samples. It distinguishes decay events of short-lived radium daughter products based on their contrasting half-lives. The system was pioneered by Giffin et al. in 1963 and later adapted for radium measurements by Moore and Arnold in 1996.
RaDeCC is particularly useful for determining the presence of radium isotopes such as 223Ra and 224Ra n seawater, groundwater, and other natural water samples. The method involves passing water samples through a column containing manganese dioxide-impregnated acrylic fiber to collect radium isotopes. The collected samples are then analyzed using the RaDeCC system to measure radium activities. This system has been widely applied in oceanographic studies to trace submarine groundwater discharges into the ocean and study coastal mixing processes. It provides a reliable and efficient way to measure radium isotopes without requiring modifications to the counting equipment or waiting for radioactive equilibrium.
Dual Alpha Spectrometer- The Mirion Alpha Analyst is the complete solution for both routine and non-routine alpha spectroscopy applications. This flexible Alpha Spectroscopy System is designed to operate for counting samples in a production “batch mode” environment or one sample at a time in a research type environment. The PIPS Detector is fabricated by the planar process using photolithographic techniques for defining device geometries. Proprietary techniques are used to provide precise control of the oxide passivation, and ion implantation is used to form the accurately controlled junctions necessary for low reverse leakage currents and thin entrance windows. The photolithographic technique lends itself to virtually any geometry which fits onto a diameter of 140 mm (Source Mirion Website)
The CO2-Pro™ FT instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection. Standard ranges from 0-600 ppm up to 0 - 2,000 ppm, along with custom ranges, provide the full spectrum of pCO2 needed for accurate measurement of water CO2 levels.
The Picarro G2301 gas concentration analyzer provides simultaneous, precise measurement of carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb) and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.
