Argon pharmacokinetics: a solubility measurement technique

Area of Science:

• Pharmacology
• Analytical Chemistry
• Biomedical Engineering

Background:

• The noble gas argon exhibits biological activity, suggesting potential medical applications.
• Understanding argon's pharmacokinetics, including its blood concentration over time, is essential for its development as a therapeutic agent.
• Current knowledge lacks experimental pharmacokinetic data for argon, hindering its pharmaceutical progress.

Purpose of the Study:

• To develop and validate a mass spectrometry-based technique for measuring argon solubility in liquids, specifically blood.
• To establish a method for obtaining experimental pharmacokinetic data for argon.
• To support the pharmaceutical development of argon for medical interventions.

Main Methods:

• Development of a prototype quadrupole mass spectrometer gas analyzer.
• Measurement of argon solubility in various liquids, including ambient air, water, and rabbit blood.
• Sensitivity testing of the developed analytical technique.

Main Results:

• The developed mass spectrometry system demonstrated sensitivity to argon across all tested liquids (air, water, rabbit blood).
• The prototype proved capable of detecting argon in biological samples like blood.
• Successful development of a novel technique for measuring argon solubility.

Conclusions:

• The novel mass spectrometry technique is suitable for measuring argon solubility in blood.
• This method provides a pathway to obtain essential experimental pharmacokinetic data for argon.
• The developed system holds promise for inferring argon pharmacokinetics through blood sample analysis, advancing its medical application.
