Buffer concentrate

Description

• General description: 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.
• Application: 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).
• Features and Benefits: Traceable to primary standard reference materials from NIST and PTBAnalytical standard GradeUncertainty data and traceability are documented in a comprehensive and batch-specific Certificate of Analysis.
• Analysis Note: pH-value (20 °C): 12.00 +/- 0.05Measured after dilution to 500 ml with a combination glass elektrode after multiple point calibration (according to DIN 19268) with reference materials for the preparation to standard buffer solutions according to DIN 19266.
