Blood gas and electrolyte analyzers play a critical role in modern healthcare, widely used in emergency departments, intensive care units, operating rooms, and other clinical settings. These devices detect blood gas components (e.g., oxygen partial pressure, carbon dioxide partial pressure) and electrolyte levels (e.g., sodium, potassium, calcium ions), providing essential support for assessing patients’ respiratory, metabolic status, and acid-base balance with rapid and accurate physiological parameters.

This article focuses on comparing the advantages and limitations of the Seamaty SG1 blood gas & electrolyte analyzer with internationally recognized brands such as Abbott, Siemens, Edan, Radiometer, and Instrumentation Laboratory, offering comprehensive and objective insights for healthcare institutions in device selection.

Summary

The Seamaty SG1 stands out among international brands for its unique advantages:

  • Ease of Use: Simplified operation with direct sampling.
  • Cost Efficiency: No reagent waste and affordable pricing.
  • Portability: Ultra-lightweight (0.6kg) with long standby.
  • Reliability: Room-temperature storage and stable performance.

For institutions prioritizing mobility, ease of use, and cost-effectiveness, the SG1 is a compelling choice. However, for facilities requiring extensive parameter menus or high-throughput testing, established brands like Radiometer or Abbott may be preferable despite higher costs.
