186 Agilent Restricted Agilent 5110/5100 ICP-OES Service Manual
6 Customer Diagnostics and Problem Solving
Gas Flows Test
• Water Chiller off or pressure incorrectly set
• Water Chiller Temperature incorrectly set
• Water Chiller vents obstructed
• Water blockage in the supply hoses or chiller
• Water blockage in instrument or instrument malfunction
Gas Flows Test
This test checks gas flows for Plasma Gases to ensure the correct flow can be set and achieved
for the complete flow range including zero flow. If this test fails possible causes include:
• Argon Inlet Pressure incorrectly set
• Blocked Nebulizer or Torch
• Faulty Gas Control Unit
RF Generator Test
This test checks the RF generator to ensure the necessary Voltages, Frequency and Current can
be produced that are required to develop and sustain a plasma. If this test fails possible causes
include:
• Faulty RF Power Supply
• Faulty SSRF Oscillator
Camera Test
This test checks the camera system to ensure it functions across the entire CCD. The test uses
an inbuilt light source (LED) that illuminates all pixels on the CCD. The test measures pixel
performance with no light (dark levels) and full brightness and reports Standard Deviations and
Linearity for the entire array. The test is also able to establish if condensation has formed on the
camera lens in which case a cleansing process (Super Boost Purge with Camera Cooling turned
off) will be invoked to clear the condensation. Review Camera Condensation section for
relevant images.
If the Camera test fails possible causes include:
• Fails Dark Current or Electronic Zero offsets
• Camera Calibration required
• Faulty Camera or Camera Board
• Fails Pixel/DLA SD’s or Linearity Test
• Condensation/Contaminants on Camera Lens
• Faulty Camera or Camera Board
