- What should I look for when I inspect my analyzer?
- Check that the water level in the DI reservoir is full up to the blue line.
- Check that the resin is black, with no air bubbles in it.
- Check for leaks throughout the analyzer.
- Check that there is still reagent left in your acid and oxidizer reagent cartridges.
- Listen for any loud grinding or squealing noises. These could indicate a problem with a motor.
- Be sure that the pump tubing has the "Y" fitting to the right side of the analyzer.
- What should I remember when I install my analyzer?
- Follow the instructions in Chapter 3: Installation in the Operation and Maintenance Manual.
- What is a good range of numbers for my calibration slopes and offsets?

- How do I backflush my analyzer?
- Follow the instructions in the "Backflushing the Analyzer" section in Chapter 8: Troubleshooting, in the Operation and Maintenance Manual.
- How do I backflush my IOS needle sipper tube vial port?
- Follow the instructions in UPW 07-16.
- How do I know when I need to backflush my analyzer, IOS, Super iOS or sipper tube?
- Backflushing should be performed if you suspect flow problems with your instrument. If it is not drawing sample or if you have unreasonable numbers, backflushing should be performed.
- How do I know that my UV lamp is on or off?
- If your analyzer is powered on, then, with a few exceptions (i.e., during TOC Autozero or when running an IC standard), your UV lamp should also be powered on. To check to confirm that the UV lamp is coming on, you can feel the UV reactor (rectangular stainless steel box that houses the UV lamp). It should be warm to the touch. If the analyzer was just powered on, it may take a few minutes to warm up.
- What do I do about negative TOC values?
- If you experience negative TOC values, then we recommend following the Backflushing procedure in the Troubleshooting chapter of the Operation and Maintenance manual to confirm that there are no flow issues. If you backflush the analyzer and do not find any issues, and it has been more than 12 hours since you last changed the resin cartridge, then perform the TOC Autozero as described in the Calibration chapter of the Operation and Maintenance manual.
- What should I send to Technical Support so they can help me?
- In order for Technical Support to best assist you with your problem, please provide them with:
- Instrument Model Type
- Instrument Serial Number
- Instrument Firmware Version
- Detailed description of problem including any Warnings or Errors that have come up, and a copy of data representing both good results and the results that are being questioned
- What do I do when I get an error?
- Refer to the Error and Warning section in Chapter 8, Troubeshooting, of the Operation and Maintenance Manual for a detailed error description.
