4 G7200-90210 (Rev. A) MassHunter Workstation Quick Start Guide
Preparing for Analysis
The following topics will help you prepare the instrument for analysis with
Agilent 7700 Series ICP- MS MassHunter Workstation.
Things to check before analysis
Utilities
• Argon gas pressure: 500 to 700 kPa
• Cell gas (Helium): 90 to 130 kPa
• Cell gas (Hydrogen): 20 to 60 kPa
• Exhaust duct (on)
• Cooling water (Chiller or heat exchanger on)
• Drain and rinse tank (not full)
Peristaltic pump tubing
• Sample, drain, and internal standard lines
Prepare tuning solutions
You will need the following standards and solutions for ICP- MS operation:
• Tuning solution (1ppb Li, Co, Y, Ce, Tl)
• Internal standard solution
• Dilute the P/A factor tune solutions 75x, then mix the two solutions 1:1 to
prepare a P/A factor tune solution for use in the lab. PA factor tuning is
used to achieve linear functionality across the detector’s pulse and analog
modes. Pulse mode is used to quantitate relatively low concentrations (ppb
range). Analog mode is used to quantitate relatively high concentrations
(ppm range).
