애플리케이션

• A highly selective electrochemical sensor for chloramphenicol based on three-dimensional reduced graphene oxide architectures.: This study presents the development of an electrochemical sensor for detecting chloramphenicol in aqueous solutions, leveraging the properties of reduced graphene oxide. Hydrogen chloride solution plays a critical role in the preparation of the graphene oxide, which is instrumental for the sensor′s high sensitivity and selectivity (Zhang et al., 2016).


• Effects of cross-linking molecular weights in a hyaluronic acid-poly(ethylene oxide) hydrogel network on its properties.: This research explores the impact of cross-linking with varying molecular weights on the properties of a hyaluronic acid-polyethylene oxide hydrogel. The use of hydrogen chloride solution in modifying the hydrogel structure is essential for optimizing its physical characteristics for potential analytical chemistry applications (Noh et al., 2006).


• [Determination of docosahexenoic acid in human serum by capillary gas chromatography].: This paper discusses a method for the determination of docosahexenoic acid in human serum using capillary gas chromatography, where hydrogen chloride solution is used during the esterification process of fatty acids, demonstrating its utility in enhancing the precision of analytical techniques (Li et al., 1997, article in Chinese).

분석 메모

Form liquid
Amount-of-substance concentration 0.0994 - 1.006 mol/L
Measurement uncertainty ± 0.0004 mol/L
Traceability NIST SRM

The concentration is determined by volumetric titration and refers to 20°C.
The amount-of-substance concentration of this volumetric solution is determined with standardized sodium hydroxide solution (article number 1.09141). The sodium hydroxide solution is standardized by hydrogen chloride solution (article number 1.09060) which has been standardized against volumetric standard Tris(hydroxymethyl)aminomethane (article number 1.02408).

This volumetric solution is traceable to a primary standard reference material (SRM) from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 723 Tris(hydroxymethyl)aminomethane) by means of volumetric standard Tris(hydroxymethyl)aminomethane (article number 1.02408), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.

Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals.
