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...
Tips for Selecting the appropriate Nutrient Analyser
Flow injection analysis first appeared in the 1970’s and has evolved into a larger group of automatic chemical analysers. The current technologies in this group are: Flow Injection Analysis (FIA) Segmented Flow Analysis (FIA) Discrete Analysers Different...
Camera viewing of SFE
Normally the Supercritical Fluid Extraction process is conducted in thick walled vessels that do not allow observation while processing. Applied Separations now have designed a viewing port that can be installed in any of their vessels. A special camera can be...
Discharge Sampling – Load Sampling
For tanker discharge, the WaterSam AutoSam provides a complete automated discharge and sampling system. The system comprises: Driver Card reader & identification. Fluidics connections, mag flow meter,conductivity/pH sensors. Autosampler to take...
Portable In-situ Water Analysis
For field applications, the WIZ probe is able to measure up to 4 analytes in a water column. Detection limits are down to low ppb for all typical reported compounds and deployment can be for up to 1 month unattended. Reliable methods are used for NH4 (fluorimetric)...
