What to do if there is an abnormal baseline in Shimadzu Security Sensors?

Grant CarrilloJul 30, 2025
An abnormal baseline in your Shimadzu Security Sensors might be caused by several factors. Start by checking the electrical connector to ensure it's securely connected. Impurities in the carrier and detector gases can also cause this issue; try replacing the filters, tubes, joints, or switching to a higher purity gas. Gas leakage can also lead to an abnormal baseline, so check for leaks and correct any faulty piping. Stray light can interfere with the baseline; use a dark film to locate the source and block the light. Ensure the shield ring is at the correct height and purge the exhaust ventilation to remove any water drops. If the APC has failed, contact Shimadzu technical support.

How to fix baseline drift in Shimadzu Security Sensors?

Felicia BradyAug 4, 2025
Baseline drift or meandering in Shimadzu Security Sensors can stem from several causes. Impurities in the carrier and make-up gases are a common culprit; try replacing the filter, tubes, joints, or using a higher purity gas. Gas leakage can also cause this, so check and correct any leaking piping joints. Contamination of the injection port or glass insert can also lead to baseline issues; clean or replace the glass insert and condition the column. Additionally, stray light can cause baseline drift, so identify and block any light leaks. If the temperature or flow rate of each section is unstable, contact Shimadzu technical support.

If you are not getting any peaks on your Shimadzu Security Sensors, the hydrogen flame may have gone out; try to ignite it again. Another possibility is quenching, so you should check the analysis conditions.

If the flame is not igniting or keeps going off in your Shimadzu Security Sensors, it could be due to several reasons. First, ensure that the column is properly connected. Check that hydrogen gas and air are being supplied at the correct flow rates. If the igniter filament is blown, it needs to be replaced (contact Shimadzu technical support). Also, verify that the detector temperature is not too low and that the shield ring is at an adequate height. If the APC has failed, contact Shimadzu technical support.

Why won't the zero adjustment work on my Shimadzu Security Sensors?

If the zero adjustment is not working on your Shimadzu Security Sensors, it might be due to stray light. Try to locate where the light is leaking using a dark film and block the stray light.
