Optics Test
Optics Test
The Optics Test is a check of the Instrument Optics with a dry Plasma (No Sample Introduction).
That is, the Instrument looks for specific Argon peaks and intensities from the plasma and
compares both Axial and Radial values (depending on instrument model) to validate both the
pre-optics and Polychromator optics. The possible failure modes are as follows:
• Axial/Radial intensities too low
• Contaminated window or windows
• Pre-optics misaligned
• Shutter closed values too high
• Sticking shutter or failed shutter control circuit
Instrument Performance Test
Instrument Performance test is a suite of tests to validate the Instrument as a system across
the entire wavelength range. It must be run with the Advanced Valve System test in bypass
mode. The possible failure modes and causes are as follows (assumes previous tests have
been run and passed):
• Failing Sensitivity Test
• Incorrect Sample Introduction setup
• Contaminated Blank
• Incorrect Concentration of Wavecal Solution
• Contaminated Spraychamber
• Optics Purge time too short
• Failing Resolution Test
• Optics misaligned
• Failing Precision Test
• Incorrect Concentration of Wavecal Solution
• Contaminated Spraychamber
• Incorrectly adjusted pump tubes
• Blocked Drain
• Partially blocked Injector
Advanced Valve System Test
The Advanced Valve System test runs a Worksheet to test the function of the Switching valve
and pump. The test must run with a sampler connected. This test assumes Instrument Tests
have previously passed The possible failure modes and causes are as follows:
• Failing Precision (%RSD’s)
• Incorrect Sampler setup
• Leaking Fittings
