Importance of Degassing Fluids

Feb 7, 2023 by IDEX Health & Science

Degassers avoid inaccurate sampling, maintain throughput and reduce errors by removing dissolved gases – even across complex fluid systems – before they outgas into bubbles. Utilizing degassing in your fluidic path is essential for consistent and accurate results.

Benefits of Degassing

  • Greatly improves precision by degassing fluids far below the saturation point so instrument operations remain bubble-free
  • Avoids repeat sampling to detect inaccurate readings, which reduces throughput along your fluidic path

Temperature, pressure, reagent concentration, and shock or agitation are all common variables that reduce the saturation point of systems fluids, resulting in outgassing that forms bubbles. If bubble formation is not initially identified, sample assessment may be flawed.

Produce consistent and accurate sample results by incorporating a degasser in your instrument. Degassers greatly improve precision by degassing fluids far below the saturation point so instrument operations remain bubble-free. As the graph below demonstrates, degassers greatly increase accuracy for dispense volumes over time, in standard operation.

IDEX Health & Science degassers manage efficiency across a wide range of flow rates and conditions with closed-loop vacuum control, to greatly enhance run-to-run reliability and throughput, while maintaining dispense accuracy to avoid sample loss.
