Total N, P and Oxyhalides with one column

Total N, P and Oxyhalides with one column

Total N, P and Oxyhalides: One system, all of the parameters Ion chromatography is the chosen technique for oxy-halide analysis and, with persulfate digestion, quantification of total nitrogen and phosphorus is now simpler with ion chromatography too. While both of these applications are ideal for environmental laboratories, they have required...

Liquid handling, accurate results depend on it

Liquid handling, accurate results depend on it

Accuracy is only a heartbeat away High precision instrumentation is used to improve repeatability and achieve lower detection limits. Ion chromatography certainly falls into this category with some applications achieving detection limits down to 1 ppt. Liquid and sample handling While instruments may be capable of these low detection limits,...

Maintaining your Metrohm IC

Maintaining your Metrohm IC

Care for your instrument, it will love you for it! Like your car, complex laboratory instruments require maintenance. Unlike cars, laboratory instruments cannot run at “near optimal” performance. While your car will keep running if you don’t top up the windscreen washer fluid, an IC will not give the correct...

Are you contaminating your sample from your grinding tools?

Are you contaminating your sample from your grinding tools?

Reliable and accurate analysis results can only be guaranteed by reproducible sample preparation. This consists of transforming a laboratory sample into a representative part sample with homogeneous analytical fineness. Retsch offers a comprehensive range of the most modern mills and crushers for coarse, fine and ultra-fine size reduction of almost...

The art of milling, the importance of correct sampling and dividing

The Art of Milling: the importance of correct sampling and dividing

A faultless and comparable analysis is closely linked to an accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results. Rotating dividers and rotary tube dividers are an important means to ensure the representativeness of a sample and thus the reproducibility of the analysis....

Alkalinity in drinking water

Alkalinity in drinking water

Public water supplies are vital resources and rather costly infrastructures.  High alkalinity concentrations in drinking water cause scale deposition in the water distribution system. As a consequence this scaling entails rather extensive and costly maintenance issues for the municipalities. Keeping the alkalinity in the desired range and thus minimising maintenance...
