Thermo Scientific’s Niton Field X-ray Lab (FXL) equipped with the new Thermo Scientific z-CAL, enables users to more accurately detect oil-bearing strata, improve mud-logging and support geo-steering. This capability can be attributed to its improved ability to analyze trace elements and light elements, including low levels of magnesium and aluminum, in prepared samples and with or without helium, depending on the desired performance. http://www.thermoscientific.com/
