Cecil Instruments add a fully redesigned electrochemical detector to their range
Cecil Instruments have added a new eclectrochemical detector to their range for the detection and analysis of even very small amounts of analytes.
Cecil Instruments are leading UK designers and manufacturers of HPLC and Ion Chromatography systems and Visible/UV Spectrophotometers. Now in addition to Cecil Instrument’s existing range of robust, reliable and accurate instrumentation they have added a fully redesigned, innovative electrochemical detector.
Electrochemical detection (ECD) is a very selective and sensitive detection technique used in conjunction with HPLC, uHPLC and Ion Chromotography to accurately analyse even very low concentrations of anylates. Sensitivities of
10 -15 mol can be achieved making it suitable for detecting biomolecules such as the neurotransmiters serotonin, dopamine and noradrenaline.
It is also idea for trace element investigations at crime scenes, where even the smallest amount of a residual drug, environmental contaminant, carbohydrates poison, paint, metabolites or pesticide might be critical.
The principle of amperometric ECD is elegant and involves the introduction of a sample separated on a column into the ECD cell where reaction takes place at an electrode. Eluted electrochemically active substances react at the electrode and a current is generated which is amplified. Data is collected on a computer where by comparison with calibration standards, the signal can identify the elutate and its concentration.
The Cecil Instruments’ ECD may be used in three modes, DC, scanning DC and pulsed amperometric and glassy carbon, gold, silver and platinum working electrodes may be used, in con junction with a choice of reference electrodes.
This ECD may be added to Cecil Instruments’ modular Adept and Q-Adept HPLC and IonQuest Ion Chromatography systems as well as many third party liquid chromatography systems. Operation is through the detector’s stand-alone control keys. It can also be used in series with other detectors, such as the Cecil WaveQuest ultra fast scanning UV/Visible detector. Plus, the use of Cecil Insgtrument’s ECD in conjunction with the easy- to-use PowerStream chromatography software, provides for 21 CFR part 11 compliance.
