Bethanechol and HPTA (2-Hydroxy-Propyl-Trimethyl Ammonium) besides Sodium and Calcium (Metrosep C 6 - 250/4.0)

4 Mar 2014

Bethanechol is a pharmaceutical compound which is used to treat urinary retention. This application note describes the determination of this by cation chromatography with direct conductivity detection. Results demonstrate that bethanechol is well separated from its degradation product 2-hydroxypropyltrimethyl ammonium (HTPA) and the standard cations.

940 Professional IC Vario

Metrohm AG

With the 940 Professional IC Vario system, Metrohm sets a new standard in ion chromatography. 940 Professional IC Vario stands for maximum flexibility combined with most easy operation and perfect reliability. Entirely modular by design, the new 940 Professional IC Vario meets your particular requirements while keeping you perfectly flexible. Based on one and the same system, you can configure any IC system you want or need.All solutions – including standards – are produced fully automatically, if desired. Starting with sample injection, the system works completely autonomously. Moreover, it is self- monitoring: All system and method parameters are permanently checked; if any system component should require maintenance, the system tells you so – with a message in plain text.The 940 Professional IC Vario system provides superior reliability of both the system itself and the analytical results produced on it: Because the system is self-monitoring, operator errors are virtually ruled out. You can absolutely rely on your measuring results. Moreover, all results can be traced back to every single step of the analysis and even sample preparation. Thus, even the strictest audits are no reason to worry any more.940 Professional IC Vario Features: Modular high-performance ion chromatography system. Unlimited possibilities for system configuration. Compact dimensions, small footprint. For routine analyses and research applications in the ng/L- to %-range. Highest sensitivity for lowest detection limits. Intelligent system components for reliable results. Wide range of detection options: conductivity, UV/VIS, amperometry, ... Free choice of suppressor and column. All gradient options. Inline eluent preparation integrated in the system. Multi-language MagIC Net software for intuitive and simple operation. Complies with GLP and the FDA regulations. Compatible with the unique and partly patented Metrohm Inline Sample Preparation techniques (MISP). Complete automation for high sample throughput. Low maintenance costs and long lifetime. Rugged Swiss quality.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.Drug DeliveryDrug Delivery refers to dosage form, route of administration, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effect. Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. Active PharmaceuticalsThe Active Pharmaceutical Ingredient (API) of a drug is the component that causes the direct effect of the product. The remaining inactive components are known as excipients.PharmaceuticalsPharmaceuticals are medicinal drugs used in healthcare to diagnose, prevent, cure and treat illnesses. Pharmaceuticals that are excreted after use appear in wastewater and can have detrimental effects on the environment.
