RM VOC MIX-2 - ASTASOL® - CH CE281M Calibration standard solution for chromatography in CERTAN® capillary bottle

Significance of the topic

Accurate quantitation of volatile organic compounds depends on well characterised calibration solutions Such reference materials ensure measurement traceability and support quality systems in environmental clinical and industrial analysis

Objectives and overview of the document

This identification sheet presents details for a multicomponent calibration standard ASTASOL CH CE281M also known as VOC MIX 2 The primary aim is to define composition certified values and handling requirements for this solution used in chromatographic determinations

Methodology and instrumentation used

Gravimetric preparation using electronic balances and class A volumetric flasks ensures high accuracy Purity corrections account for material impurities

• Analytical balances for weighing neat reagents
• Class A volumetric glassware for precise dilution
• Amber glass CERTAN bottles for storage
• Methanol Picograde as solvent matrix

Main results and discussion

The assigned concentration for each of eight halogenated compounds is 1000 plus minus ten micrograms per millilitre at twenty degrees Celsius Expanded uncertainty covers weighing dilution and purity factors Quality control can be performed by comparison with an independent internal standard solution Proper storage in the dark at five to ten degrees Celsius preserves solution stability

Benefits and practical applications of the method

This certified calibration solution simplifies preparation workflows reduces potential errors and supports compliance with ISO quality requirements It is suitable for environmental monitoring food safety and industrial quality control where halogenated volatile compounds are analysed

Future trends and potential applications

Development may include extension to additional target analytes matrix variations and integration of digital data certificates Remote or on site calibration modules and microvolume formats could further enhance analytical agility

Conclusion

The provided reference material delivers traceable calibration for key halogenated compounds enabling reliable chromatographic analysis Its documented preparation and uncertainty evaluation align with international standards ensuring consistent performance
