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...

Monitoring for gluconic acid for botrytis affected grapes

Monitoring for gluconic acid for botrytis affected grapes

Gluconic acid is used globally as a rapid screening tool for assessing fruit quality on incoming fruit, even so far as influencing the price and/or rejection criteria in vineyard contracts. Gluconic acid Gluconic acid – D-Gluconic acid (gluconate) is a metabolite of Botrytis and can be a useful marker for...

Arsenic speciation

Arsenic speciation

Arsenic speciation: More options than you may have expected The determination of total Arsenic does not give an accurate representation of the potential toxicity to humans and animals. This is due to the variation in bioavailability of different species resulting in varied toxicity.    Inorganic Arsenic As(III) and As(V) Inorganic...

RETSCH: CryoMilling for protein analysis

CryoMilling for protein analysis

Proteins such as DNA and RNA are problematic to extract due to temperature sensitivity. That’s where the CryoMill comes in! The CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus the sample...

Conductivity Measurement. Get it right!

Conductivity measurement. Get it right!

When 5 rings are better than 3: Wider measuring ranges and higher precision in conductivity. Conductivity is a staple of laboratory analysis. Water, petroleum, mining and chemical processes all require it. However, measurement in different samples require different probes. And not all conductivity probes are created equal. Each conductivity probe...
