Partial Loop Injection

Partial Loop Injection (Ion Chromatography)

Increase the flexibility of your IC. Analytical instruments are designed to run with sample concentrations in optimal windows and preferred matrices. Unfortunately, not all samples are created equal. If you have samples from a range of sources, you are likely to have concentrations and matrices over a wide range too....

NIR performs better with homogenous size reduction

NIR performs better with homogenous size reduction

Near Infrared Spectroscopy is the most important analysis method for the determination of protein content, moisture, fat and ash in feeds and forage. The advantage over classical methods such as Kjeldahl is the simultaneous determination of several parameters. Moreover, NIR spectroscopy is a quick method which neither requires consumables nor...

Why size reduction? The influence on standard deviation

Why size reduction? The influence on standard deviation

A reliable and accurate analysis can only be guaranteed by reproducible sample preparation. The "Art of Milling" describes the process of turning a laboratory sample into a representative part sample with homogeneous analytical fineness. For this task RETSCH offers a comprehensive range of the most modern laboratory mills and crushers...

Automated sample preparation for halide analysis

Automated sample preparation for halide analysis

Analysis of mining and mineral samples does not need to be labor intensive. Mining and mineral samples, by their nature, contain high levels of transition metals, dust and particles as well as a wide range of analyte concentrations: all of the things that make life difficult when using a highly...

Fats, proteins, oils and Ion Chromatography

Fats, proteins, oils and Ion Chromatography

Protein and IC, now with simple sample preparation. Fats, proteins and oils provide challenges for analysis with ion chromatography. Fats and oils generally mean a non-aqueous sample, and all sample must be aqueous. Proteins provide a challenge by blocking columns and being difficult to filter. Historically, these samples either have...
