S4 TStar - The Star of TXRF
For decades, X-ray fluorescence (XRF) spectroscopy has been widely used in multiple industries for elemental analysis of solid and petrochemical samples, with detection limits below the PPb level. TXRF expands the application range of XRF, enabling the analysis of trace elements in liquid samples, suspensions, and membranes. Therefore, TXRF has become an ideal alternative method for atomic absorption spectroscopy (AAS), inductively coupled plasma emission spectroscopy (ICP-OES), or mass spectrometry (ICP-MS). Now, S4 TStar has set new standards in performance, self-control, and quality for desktop TXRF spectrometers.
Excellent sample universality
S4 TStar is a highly versatile tool that can analyze various types of samples on different reflective carriers.
ICP can only analyze completely dissolved liquid samples.
