How to fix random air spikes in Hach Measuring Instruments?
Random air spikes in Hach Measuring Instruments may occur because air is introduced into the system. Degassing the carrier solution and other reagents with helium may be necessary. Adding a back-pressure loop to the manifold might also help keep the air in solution.
What to do if there are constant air spikes in Hach Measuring Instruments?
If you observe constant air spikes in your Hach Measuring Instruments, it could be due to air entering the line because the reagent is exhausted. To resolve this, ensure that the reagent transmission lines are placed at the bottom of the containers.
Why are air bubbles coming out of the heater block in Hach QC8500 2 Measuring Instruments?
If you see air bubbles coming out of the heater block in your Hach Measuring Instruments, degas all reagents with helium, unless the QuikChem method indicates otherwise. Additionally, consider using a back-pressure loop to help keep the air in solution.
How to fix the heater element if it does not heat on Hach QC8500 2 Measuring Instruments?
If the heater element in your Hach Measuring Instruments does not heat, ensure that the heater temperature has been set for the specific channel under Run Properties>Analytes.
What to do if there are negative peaks in Hach QC8500 2 Measuring Instruments?
Negative peaks in Hach Measuring Instruments can occur if the carrier of a direct chemistry is spiked or contaminated with the analyte being determined. To correct this, obtain a fresh carrier solution.
How to remove white precipitate in Hach QC8500 2 when running TKN?
If a white precipitate forms inside the manifold tubing of your Hach Measuring Instruments when running TKN, run a strong solution of sodium hydroxide through all the manifold reagent lines to remove the precipitate.
Why is there an error initializing autosampler on Hach QC8500 2 Measuring Instruments?
If your Hach Measuring Instruments show an error initializing the autosampler, the sampler might be turned off, the sampler cable could be unplugged or defective, the sampler wasn't installed properly, or the sampler configuration has been changed and doesn't match what's specified on the computer. Verify the configuration of the hardware and software.
Why is the flow moving backwards in Hach Measuring Instruments?
If the flow is moving backwards in your Hach Measuring Instruments, it indicates a blockage in the manifold.
