LAMAS 4 IC - Laboratory approved metadata acquisition schemas for ion chromatography

Area of Science:

• Analytical Chemistry
• Data Science
• Scientific Instrumentation

Background:

• Metadata is crucial for describing scientific experiments and adhering to FAIR data principles (Findability, Accessibility, Interoperability, Reusability).
• Standardized metadata schemas are essential for structured data collection and management in scientific research.
• Ion-exchange chromatography (IEC) is a widely used analytical technique requiring robust metadata for data interpretation.

Purpose of the Study:

• To develop and introduce the first metadata schemas specifically for anion and cation ion-exchange chromatography measurements.
• To align these schemas with existing standards, such as ASTM E1151:1993, for ion chromatography.
• To provide publicly accessible JSON schemas for immediate use and adaptation in various IEC applications.

Main Methods:

• Development of metadata schemas using the JSON schema standard.
• Alignment of schemas with the ASTM E1151:1993 norm for ion chromatography.
• Implementation and validation of schemas in laboratory settings, specifically within applied plasma science.

Main Results:

• The first metadata schemas for ion-exchange chromatography analytical methods were successfully developed and implemented.
• Schemas are aligned with ASTM E1151:1993 and utilize the JSON schema standard.
• Schemas were approved and demonstrated effectiveness in laboratory environments, including water analysis for plasma applications.

Conclusions:

• The developed metadata schemas represent a significant advancement in standardizing the documentation of IEC measurements.
• These schemas support improved research data management and the application of data science methods in analytical chemistry.
• The schemas facilitate enhanced data findability, accessibility, interoperability, and reusability, crucial for modern scientific endeavors.
