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)...
Using the Single Particle Optical Sizing (SPOS) technique, the accusizer is able to provide particle size distributions as particles versus size or any other distributions eg. such as volume % vs size etc. Importantly the total particle concentration can be shown or...
The Micromac unit is designed for industrial and environmental applications. It can be custom designed to meet the most challenging low levels encountered in environmental deployments,including TOC in sea water, to robust units that can work in tanneries. The analyzer...
Total N is measured in the same device with UV digestion + UV reduction for Total Nitrogen. Colorimetric, acidic digestion and UV Digestion is used for Total Phosphorus.
After a prolonged dry period, heavy rainfall in a catchment area can yield unacceptably high levels of organics and toxic analytes in a river system flash flood. Water-treatment plants that process this raw water with high agricultural analytes, then have flocculants...
The digestion of sulphide ores for analysis by AAS ,ICP or ICP-MS creates two potential problems. 1. Sulphide ores can contain silicates which are difficult to digest by aqua regia and require use of HF which requires special handling and safety...
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...
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...
A typical spectrometer will process wavelength spectra to provide some measure of the analytical makeup of a sample. Within that spectrometer will be some separating device such as a monochromator or polychromator to measure the strength of the wavelength of...
To measure the quantity of a metal in a sample, the metal must first be dissolved completely into a solution (called an analyte) before it can be analysed using AA (atomic absorption) or ICP Inductively Coupled Plasma. For semi quantitative analysis, hot plate...
