Typically medicinal cannabis production involves an initial extraction from the flower bud material using Supercritical Fluid Extraction (SFE), solvent extraction or similar technique to produce a concentrate of terpenes and cannabinoids. The basic SFC...
Medicinal Cannabinoid production is an emerging market that overlaps well with supercritical fluid techniques. For initial extraction of the cannabinoids and terpenes, supercritical fluid extraction can be used to separate the raw cannabinoid oils...
Various organs in animals have the ability to accumulate heavy metals. An example is mercury (Hg) in shark liver. A commercial application is monitoring Cadmium in sheep liver which can be used for paté usage. The universal limit set for Cadmium is lower than...
Monitoring of heavy metals in various foods is being continually updated with specified maximum allowable levels. Determination of Cadmium in liver is an example. Using a high sensitivity procedure, Cadmium was detectable in liver samples down to 7ppb; more than...
A German university, Technische in Darmstadt, has found a novel procedure to create covalent organic and metalorganic framework compounds. Using the Berghof DAB high pressure digestion vessels they were able to synthesise these structures at...
Rigaku have found an ideal application for their new 60Kv XRF DE model. With the higher voltage it allows the analysis of all the rare earth elements with moderate resolution on the K series lines. This improves sensitivity and detection levels. Liquid process plant...
History of the AAS In 1940 Alan Walsh was a young physicist working at the British Non Ferrous Metals Laboratories during World War II. His work included determination of metal composition from the debris of enemy bombers. He developed a number of methods for rapid...
For analytical spectroscopy, there are two main categories of instruments – based on either atomic absorption or atomic emission. An example of an instrument using atomic emission is an Inductively Coupled Plasma (ICP) Spectrometer, whilst an example of one...
The Alec range of equipment can be either powered by on board lithium battery or cabled power. The battery option means that difficult measuring locations such as tidal flow past reef atolls can be measured by merely anchoring the instrument against the coral. Most...
