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.
  • Look for white crusty buildup on the oxidizer syringe. Significant buildup can impact the delivery of oxidizer, and the syringe will need to be replaced.
  • Look for crusty buildup on any of the stainless steel fittings. If you do see buildup, loosen the fitting, rinse it off with DI water, and then tighten the fitting again
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?

TC PPT SLOPE NA 1.4229 to 2.2631
TC A NA -0.2328 to 0.2010
TC B NA 0.8836 to 1.2187
TC C NA -4.7612e-06 to 4.4389e-06
TC D NA -4.6927e-11 to 4.7907e-11

Single-Point Calibration

Constant Units Typical Range
IC SLOPE NA 0.95 to 1.05
TC SLOPE NA 0.95 to 1.05
What is a good range of numbers for my offsets?
Constant Units Typical Range
TOC OFFSET ppb -7.1 to 7.1 UPW
-18.7 TO 10.0 Air Saturated
IC CELL OFFSET μS/cm 0.000 to 0.040
TC CELL OFFSET μS/cm 0.000 to 0.040
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, needle sipper tube vial port?

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
