What to do if I see low or unsteady current in my Beckman Coulter Laboratory Equipment?
- D
  Derrick MataAug 12, 2025
  If you're experiencing low or unsteady current with your Beckman Coulter Laboratory Equipment, it might be due to a plugged capillary. Try rinsing the capillary with DDI water at 100 psi for 10 minutes, and then perform the capillary conditioning method. Another potential cause is air bubbles in the gel. In that case, degas SDS-MW Gel Buffer under 5 to 15 Hg vacuum for 5 minutes.

How to fix unsteady current after rinsing the capillary in Beckman Coulter Laboratory Equipment?
- S
  Shawn CookAug 15, 2025
  If rinsing the capillary doesn't solve the unsteady current issue in your Beckman Coulter Laboratory Equipment, the capillary may need to be replaced.

Why are there no peaks on my Beckman Coulter PA 800 plus Measuring Instruments?
- D
  Daniel JonesAug 20, 2025
  If you are not seeing any peaks, consider the following possibilities: Ensure your LIF detector is calibrated by referring to the LIF calibration section. Verify that your laser is turned on. Check the probe stabilizer connection to the lock-down bar. Confirm the voltage is properly set in the method, ensuring the correct polarity (orange LED should be on). Check for bubbles in the sample vial. Inspect the capillary window for damage, and if broken, replace the capillary and clean the probe aligner with a water-moistened cotton swab.

What to do if I have low intensity peaks on Beckman Coulter Measuring Instruments?
- L
  Laura WoodAug 25, 2025
  Low intensity peaks can occur if the labeling reaction was not carried out properly. To ensure a successful labeling reaction: * Make sure that the protein is in a non-tris buffer, as Tris will compete with your carbohydrate. * Ensure that the carbohydrate pellets were fully dried, as any water residue will interfere with the labeling reaction yield. Also, enzyme activity may vary, so adjust the amount if the reaction yield is lower than expected.

What to do if there is a shift in migration time between runs on Beckman Coulter PA 800 plus?
- K
  Kathleen HurstAug 27, 2025
  Migration time shifts can be associated with the length of injection. Ensure that injections are between 3 and 20 seconds at 0.5 psi, adjusting the injection time based on concentration.

How to fix low current in Beckman Coulter PA 800 plus Measuring Instruments?
- M
  Michelle GarciaAug 31, 2025
  To address low current issues: * Use approximately 50 cm N-CHO capillary total length (50 ?m I.D.) for a predicted current that should be steady at around -15 ?A. * If the capillary may be blocked, use Direct Control to perform a 70 psi rinse with water to unblock it.

What causes spikes in electropherogram in Beckman Coulter PA 800 plus and how to resolve it?
- J
  jesuswashingtonSep 4, 2025
  Spikes in the electropherogram can be caused by air dissolved in the gel buffer. To resolve this, sonicate the gel for 5 minutes.

Why are there extra peaks in my Beckman Coulter PA 800 plus?
- C
  Charles MedinaSep 7, 2025
  Extra peaks can be caused by contaminants left over from the manufacturing process of vials. It is very important to use extra clean 0.5 mL micro-centrifuge vials, especially during the labeling step.
