  • 1.5 Argon Online Dilution System (AGOD)
    Suitable for complex sample injection analysis in high salt matrices, with high salt resistant injection analysis and online dilution working mode. AGOD utilizes a conventional injection system combined with stable plasma conditions, resulting in deeper sampling depth and lower carrier gas flow rate. A second argon gas flow is added between the atomization chamber and the torque tube to dilute the sample aerosol before entering the torque tube, reducing the total amount of sample entering the plasma. No reagents or dilution solutions need to be added for direct analysis

2. Stable ICP ion source
