NEX CG II series (NEX CG II and NEX CG II+) is the high-end model of RIGAKU which draws attentions with its unique secunder target excitation. Therefore, extremely low signal/noise ratios can be achieved even in case of light elements. Among the unit’s strenghs are measurements with high and complex matrix: accurate determination of petrochemical samples, wastes, alloys can be done easily. A lot of accessories can be attached to the unit such as vacuum pump or sample spinner. Both traditional empirical calibrations and standardless measurements (scattering FP) are available.
