Used ESA Coulochem #293671245 for sale

ESA Coulochem is a lab equipment and accessory used for a variety of electrochemistry techniques. It is a high-performing, compact and versatile Coulometric detector for HPLC and capillary electrophoresis. This equipment is based on coulometric detection (potentiometric) with high resolution, stability and accuracy. Coulochem makes use of a measurement method which is measured in coulombs. The Electrochemical cell consists of two graphite electrodes that are used to collect electrons from either oxidised or reduced species as they pass through the cell. This technology was especially developed for amperometric detection, which is a qualitative and quantitative analysis method that can be used to detect and measure the concentration of an analyte of interest (redox molecules). This is done by taking advantage of the fact that the electrons released from the oxidized molecule can be quantified and used to calculate the concentration of the molecule. ESA Coulochem is also capable of performing cathodic or anodic peak analysis, depending on the application. Coulochem is designed to be used with high-pressure liquid chromatography (HPLC). This technique uses a pump to inject a sample into a stream of mobile phase (normally a solution of a solvent such as water or methanol) through a chromatography column. The electrode setup then allows current flow between the anode and cathode points, and the current flow is used to measure the sample as it travels through the column. This is an ideal solution for the analysis of small molecules, such as the radicals and ions that are produced in the oxidation of drugs and pharmaceuticals in HPLC systems. ESA Coulochem features low detection limits for electroactive substances, which are typically only in the nanomolar concentrations. The detector also includes built in temperature control and detection cell that helps to prevent the issue of false positive results due to temperature instability. It also has the capability to measure apparent potentials from -1000 mV to 1000 mV, making it suitable for a variety of complex electrochemical measurements. It is complete control of the stirring speed and an autoshield option also available, which can be used for low-noise measurements. Coulochem has a user-friendly interface, allowing operations to be performed with little training. Additionally, all settings, controls, and run parameters can be adjusted quickly and simply via the intuitive user interface. ESA Coulochem is compatible with many liquid chromatograph systems and is widely used for applications involving pharmaceuticals, natural products, environmental analysis, and drug metabolites.
