Measuring Potassium in Human Saliva with the HORIBA K‑11 Compact Ion Meter

Accurate potassium (K⁺) measurement in human saliva is increasingly valuable in clinical research, sports science, occupational health, and point‑of‑care screening. Saliva offers a non‑invasive, easily repeatable sampling matrix that reflects physiological changes in electrolyte balance. The HORIBA K‑11 Compact Ion Meter provides a fast, reliable, and user‑friendly solution for quantifying potassium in saliva without the complexity of traditional laboratory instrumentation.

Why Measure Potassium in Saliva?

Potassium plays a central role in:

• Neuromuscular function
• Fluid and electrolyte balance
• Cellular metabolism

In saliva, potassium concentrations are typically higher than in blood plasma and can respond dynamically to hydration status, stress, circadian rhythm, and physiological load. Because saliva collection is painless and repeatable, it is especially well suited for:

• Longitudinal monitoring
• Field or workplace testing
• Sports and performance research
• Preliminary screening or feasibility studies

(Note: Salivary potassium testing is intended for research and screening purposes and is not a substitute for clinical blood diagnostics.)

The HORIBA K‑11 Compact Ion Meter

The HORIBA K‑11 is a handheld potassium‑specific ion meter designed for rapid measurement of K⁺ activity using an ion‑selective electrode (ISE).

Key Features

• Potassium‑specific ISE for selective and sensitive detection
• Compact, handheld design for portability and field use
• Small sample volume requirement (typically a few drops)
• Fast response time, delivering results in seconds
• Simple calibration with standard potassium solutions
• Digital display for clear, immediate readouts

Advantages of the K‑11 for Saliva Testing:

1. Non‑Invasive Sample Compatibility
2. Rapid, On‑Site Results
3. High Selectivity for Potassium Ions
4. Ease of Use and Minimal Training
5. Portability for Field and Remote Applications

The HORIBA K‑11 Compact Ion Meter combines accuracy, speed, and portability, making it an excellent tool for measuring potassium in human saliva. Its non‑invasive compatibility, rapid results, and ease of use allow researchers and practitioners to expand electrolyte monitoring beyond the traditional laboratory.

For anyone seeking a practical, field‑ready solution for salivary potassium analysis, the HORIBA K‑11 delivers reliable performance in a compact and accessible format.
