Subcritical Water Extraction is considered an environmentally responsible "green chemistry" due to some key operation considerations: 1. Minimal chemical consumption during the extraction process (water is the main solvent used). 2. Power usage for...

Supercritical Fluid Chromatography (SFC) is a relatively new technique that offers several advantages including faster run times, better resolution and more concentrated separations.The limitations of SFC are: it has only been proven on small molecular...
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...
The unique attributes of the water molecules extend into the higher temperature region from 100 - 300 deg C. As temperature increases the Dielectric Constant lowers to approach that of more polar molecules such as ethanol and acetone. Image via Core Separations With...
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...
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...
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...
