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...

How Subcritical Water Extraction compares to other extraction mediums
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...
Selection Criteria for a Discrete Analyser
The automated chemical analyzer industry has seen the traditional Continuous Flow Analyzer (CFA), having an alternative technology available with the Discrete Analyzer. Discrete analysers were developed in the mid-2000’s for the large clinical...
Subcritical Water – A Green Chemistry Extraction Process
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...
