How to fix baseline drift or meander on Shimadzu ECD-2010 Exceed Security Sensors?
- J
  Jennifer CochranAug 7, 2025
  To fix baseline drift or meander on Shimadzu Security Sensors, consider these potential causes. If air is trapped in the flow line, purge the air completely. If the carrier gas or make-up gas is not flowing correctly and air is mixed in, correct the flow conditions. Contamination of the injection port (glass insert) or column could also be responsible; clean or replace the glass insert and condition the column. Unstable temperature in any section can cause baseline issues, so monitor the temperature of each section. Similarly, an unstable flow rate can cause problems; monitor the pressure and flow rate.

What to do if zero adjustment does not work on Shimadzu ECD-2010 Exceed?

  If zero adjustment does not work on your Shimadzu Security Sensors, the issue might be due to air trapped in the flow line; purge the air completely. Alternatively, the carrier gas or make-up gas may not be flowing correctly, with air mixed in; correct the flow conditions of these gases. The cell could also be contaminated; check the cell and consider sending the ECD unit for cleaning. Finally, if the current value is too large, set a smaller current value.

Why is the linearity of the calibration curve significantly poor on Shimadzu ECD-2010 Exceed Security Sensors?

  Poor linearity of the calibration curve on Shimadzu Security Sensors can stem from several causes. Impurities in the carrier or make-up gas may be the culprit, so try purging the air inside the flow line completely, replacing the filter, the plumbing parts, or switching to a higher purity gas. Column contamination can also lead to this issue, requiring column conditioning. Another potential cause is a contaminated cell, which should be checked and potentially cleaned. Adjusting the current value, lowering it, may help, but be aware that this can reduce detection sensitivity. Finally, a makeup gas flow rate that is too low can also affect linearity; increasing the makeup gas flow rate might resolve the problem, but this can also lower the detection sensitivity.
