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...
Digestion of Liver Samples
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...
Analysis of Cadmium in Liver
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...
AAS Gold Analysis with DIBK
Hydrothermal Zeolite Synthesis and Production of COFS and MOFS
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...
Simultaneous Rare Earth Element Analysis by EDXRF
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...
Pt, Pd, Rh in Recycled Automotive Catalysts
The measurement of Pt, Rh & Pd in recycled automotive catalytic converters can be achieved by using the Fundamental Parameters program to reference a matching library of elemental profiles. The full elemental analysis (up to 25 elements) is displayed and...
Spectrometers: Emission vs. Absorption Instruments
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...
Remote Measurements
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...
What is Zeta Potential?
Zeta potential indicates the stability of a colloidal dispersion. A colloid is a particle, 10-8 to 10-6m in size which when mixed in a dispersing medium is termed a colloidal dispersion. Aerosols (solid or liquid colloids) in a gas (dispersing medium), emulsions...
