Descripción

Descripción general

The Titrisol^® reference buffer concentrate [phosphate/sodium hydroxide; pH=12.00±0.05 (20 °C)] is analyzed in the ISO/IEC 17025 accredited calibration laboratory with a combined glass electrode and 5-point calibration according to DIN 19268 against a certified primary standard reference material following DIN 19266.

The Titrisol^® concentrated buffer material combines ease of use and maximum precision for the routine calibration and monitoring of pH instruments. To prepare the ready-to-use pH buffer solution, simply dilute the Titrisol^® buffer concentrate.

Aplicación

• Identification of variety-specific metabolites of basil by high performance thin layer chromatography-assisted metabolic profiling techniques: This study identified specific metabolites in different basil varieties using high-performance thin-layer chromatography, employing silica gel 60 H as the stationary phase. The technique allowed detailed metabolic profiling, aiding in the differentiation of basil varieties (Wulandari et al., 2023).

Características y beneficios

• Traceable to primary standard reference materials from NIST and PTB
• Analytical standard Grade
• Uncertainty data and traceability are documented in a comprehensive and batch-specific Certificate of Analysis.
