UHPS ultra-high pressure system is developed by RUISHENBAO® and remains the world's first automatic ultrahigh pressure pellet press to sample preparation for spectral or X-ray fluorescence analysis, which is maximum press force can reach 320T so that it press produces high-quality pressed pellets with a mirrorlike surface necessary for optimal XRF results. The UHPS achieves the desired homogeneity and stability of each individual pellet with a maximum of reproducibility. There is no dilution effect and effectively overcomes powder effect of the XRF thanks to ultra-high pressure direct powder pelletizing press mode. It greatly improves the analysis of technical indicators for XRF method for example: the detection limit, precision, accuracy and long-term stability. It effectively expands the XRF on the applicable scope for all kinds of samples. The system can be used as an important direct pressing sample technology and method for sample preparation of the XRF, XRD, laser fluorescence spectroscopy, and laser induced breakdown spectroscopy.
