A new analytical elastic recoil detection channel as a part of the IAP NASU microanalytical facility is described. The main purpose of the channel is quantitative non-destructive investigation of hydrogen in materials by elastic recoil detection technique. Due to application of the precision electrostatic spectrometer in combination with position-sensitive detector high energy and, hence, depth resolution is obtained. Relative energy resolution of the instrument ΔE/E is 3×10-4. Limit of hydrogen detection is about 10 ppm.
