Environmental monitoring does save money

High cost of environmental incidents Government monitoring of trade wastes and industrial outflows is at its highest level in history. In combination with this, the fines being handed out for exceeding trade waste limits or environmental contamination due to process failures is also at its highest. With the cost of...

Fast cyanide analysis for metal processing and extraction

Fast cyanide analysis for metal processing and extraction

Ensuring the minimum concentrations of cyanide While considered highly dangerous, cyanide is also extremely useful in metal extraction and plating baths due to the solubility of the complexes it creates with the likes of gold and copper. As regulations around the use of cyanide increase, so too does the cost...

Photometric titration of nickel

Photometric titration of nickel

Nickel-containing materials play a major role in our everyday lives – food preparation equipment, mobile phones, medical equipment, transport, buildings, power generation – to name a few. They are selected because they offer greater corrosion resistance, better toughness, superior strength at high and low temperatures, and a range of unique...

Secure your reputation and save the planet with Ion Chromatography

Wastewater monitoring in industrial processes Wastewater is now a heavily monitored product of the industrial process for many obvious reasons. Not only can contaminated water cause environmental issues, it can cost dearly. Penalties can be harsh and the reputation of the offending business can suffer greatly. Halide, nutrient and metals...

The new generation of particle characterisation – Image analysis with the CAMSIZER X2

The new generation of particle characterisation – Image analysis with the CAMSIZER X2

Particle characterisation by Dynamic Image Analysis (DIA) has become increasingly popular in recent years. This technique delivers very accurate particle size distributions in a very short time, is virtually maintenance-free and, unlike other methods like sieve analysis or laser diffraction, provides particle shape information. The CAMSIZER X2 is the latest...

Determination of Iron(II), Iron(III), total and free acid in an etching bath

Acid etching baths are used for oxide removal and cleaning of the surface of different types of steel. To keep the bath in an optimum condition the Fe2+/Fe3+ and free acid/total acid ratios must be maintained within certain limits. Auxiliary substances like hydrogen peroxide are added to influence the Fe2+/Fe3+...

Straightforward determination of fluorine in copper concentrates

Straightforward determination of fluorine in copper concentrates

CIC is a hyphenated technique combining sample digestion by pyrolysis and subsequent analysis by ion chromatography in an integrated, fully automated system. Copper concentrate is often contaminated with corrosive fluorine, which is why the fluorine concentration must be checked at regular intervals. Current laboratory techniques involve a long cumbersome fusion...
