10 HPLC Electrochemical Detection System Helps to Provide Accurate Adrenaline Analysis
Forensic examination of adrenaline involves the detection of trace concentrations, in order to acquire an accurate image of the circumstances leading to and/or possible prevention, of a criminal act. The method of detection must be sensitive, accurate, reproducible, selective, reliable and if possible, easy to use. In addition, as adrenaline is very closely related to noradrenaline and dopamine, detection techniques need to specifi cally distinguish each type of these catecholamines.
The modular Cecil Instruments ultra low noise, DC, scanning DC and pulsed amperometric electrochemical detection Adept HPLC system, with its wide choice of working and reference electrodes is benefi cial in the detection of catecholamines to low picogram/mL levels.
The electrochemical detector may also be added to third party liquid chromatography systems and to IonQuest ion chromatography systems. The Adept HPLC system includes intuitive PowerStream chromatography software, which provides for the FDA’s 21 CFR part 11 compliance. For more information visit

New Process for the Production of Uniform Particle Size Chromatography Resin Beads Announced
Purolite has announced its patented continuous process – Jetting - for the production of uniform particle size chromatography resins using two propriety manufacturing processes.
For liquid chromatography (size exclusion chromatography, ion exchange chromatography, hydrophobic interaction chromatography, reversed phase chromatography, solid phase extraction, and affi nity chromatography) it is preferable to have uniform particle size beads to provide improved kinetics, resolution, performance consistency and superior packing properties.
Classic batch emulsion polymerisation is a robust, proven technology which results in a relatively broad (Gaussian) particle size distribution. Jetting, however, is a continuous, direct manufacturing process for chromatographic resin beads with a narrow particle size distribution, resulting in higher yields and superior economics. Jetting allows for chromatographic resins to be produced relatively quickly in small or large quantities (>1000Kg) as required. The availability of consistent supplies of large volumes of chromatographic resin beads also opens up the possibility of new potential larger scale applications.
The fi rst Purolite jetting process - membrane or ‘can’ jetting - entails using a membrane with very small, discrete orifi ces, through which the polymer is passed. This device is capable of producing uniform particle size chromatographic resins from ~15 to 250 micron.
The second process, plate jetting, utilises a plate with many precisely engineered holes, through which the resin polymer is passed. Uniform particle size chromatographic resins of ~150 µm to >1000µm can be produced using this method.

Restek has expanded its selection of cannabinoid- related reference standards by adding cannabidiolic acid (CBDA). This 1,000 ppm standard is DEA- exempted, so there’s no need to purchase costly neat materials or to make your own standards, and it is prepared in acetonitrile, which helps maintain stability by preventing methylation of the carboxylic acid group on the molecule. Paired with Restek’s THC standards, it is perfect for the analysis of both neutrals and acids in cannabis products by LC and is a must for accurate quantifi cation in medical cannabis potency testing and strain ID. Restek’s CBDA standard is also a certifi ed reference material (CRM) so you know that it meets strict ISO quality requirements.
