Using CHN microanalysis to determine soil health

Exeter Analytical reports on how its Model 440 CHN Microanalyser is being used to precisely determine the percentage Carbon and Nitrogenin soil samples



Determining carbon, hydrogen and nitrogen percentage in liquid samples

Analysis can be done without sacrificing accuracy or precision and without the need for expensive liquid autosamplers



Routine CHN microanalysis of difficult sample types

Warwick Analytical Service (WAS) has developed a range of CHN microanalysis methodologies allowing them to routinely produce precise and accurate percentage Carbon, Hydrogen and Nitrogen data from a range of difficult samples.




Easy-to-understand introduction to CHN microanalysis

CHN microanalysis is a key analytical technique for determining whether or not a sample is pure



Scientists determine crystal structure of Chinese milk contaminan

A team of scientists at the University of Hull has uncovered the crystal structure of melamine cyanurate, the substance thought to be responsible for the 2008 Chinese milk scandal, which caused around 300,000 babies to fall ill.



What you eat determines your ‘nitrogen footprint’

Researchers have calculated that beef generates about twice as much nitrogen as pork, and almost three times as much as chicken or fish.



Improving data quality in nitrogen determination

Developed by Exeter Analytical Inc. for use with the Model 440 Elemental Analyzer - Linear Regression Plus is a unique software algorithm that provides unmatched accuracy in the determination of the nitrogen content of combustible samples.



Eliminate liquid nitrogen costs

The FTS Multi-Cool is a mechanically refrigerated bench top bath that eliminates the need for costly consumables such as liquid nitrogen and dry ice.



ABN2ZA and AB-3G Nitrogen Generators

Both the ABN2ZA and the AB-3G Nitrogen Generators are specifically designed to operate LCMS Instruments manufactured by Applied Biosystems/ MDS Sciex.



Airborne nitrogen shifts aquatic nutrient

The impact of airborne nitrogen released from the burning of fossil fuels and wide-spread use of fertilizers in agriculture is much greater that previously recognized and even extends to remote alpine lakes.



Nitrogen loss threatens desert plant life

As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers.



Unexpected sources of nitrogen fixation

Researchers at the California Institute of Technology have identified an unexpected metabolic ability within a symbiotic community of microorganisms that may help solve a lingering mystery about the world's nitrogen-cycling budget.



Nitrogen Mysteries in Urban Grasslands

A group of researchers established a series of long-term study plots to evaluate multiple ecological variables in different components of the urban landscape.
