Unlock the Power of Precision with GDMS Technology

 Our company specializes in high-resolution Glow Discharge Mass Spectrometry (GDMS), a sophisticated and reliable method for direct elemental analysis across a wide range of materials. GDMS is highly effective for accurately identifying elemental content, from major components down to trace levels, within various samples. By applying a potential difference between an anode and the cathode (sample material), GDMS initiates a glow discharge that functions at a molecular level. A unique advantage of this technology is the separate atomization and ionization processes, which reduce matrix effects and ensure consistent results using standard Relative Sensitivity Factors (RSF). 

 In the GDMS process, atoms within the sample undergo atomization and ionization in the plasma. Once ionized, these ions (M+) move beyond the cell and accelerate down a flight path. They pass through both an electrostatic analyzer (ESA) and a magnetic analyzer, which enhance the separation of ions before they reach the detector. Depending on signal strength, detection occurs via either an electron multiplier or a Faraday cup, offering highly accurate measurements.
