Report on Portable NIR Spectrometer use to Measure the Nitrogen Content in Grain
Analytik is pleased to report on the use of AgriSpec portable near-infrared (NIR) spectrometer from ASD Inc at Rothamsted Research Ltd. The spectrometer is used for nitrogen measurements in grain.
The AgriSpec line of NIR instruments is portable and precise. They use an improved optical design providing a faster speed of analysis while yielding the best possible analytical results on a wide range of materials, including solids, powders and liquids. Improvements to the AgriSpec line provide the user with higher quality measurements that identify and quantify materials in real time with minimal sample preparation. These non-destructive measurements result in minimal or zero sample waste. Users enjoy the ability to measure multiple properties simultaneously.
Rothamsted Research is the longest running agricultural research station in the world, providing cutting-edge science and innovation for nearly 170 years. Andrew
Riche has worked at Rothamsted since 1994 on the agronomy and physiology of arable crops. His current work is focused on wheat pre-breeding research, studying a diverse range of germplasm looking particularly at improving nitrogen and phosphorus use efficiency.
One of his routine tasks is to measure the amount of nitrogen in grain. Routine measurement was performed with a combustion analyser but with increasing workloads and extended time for sample preparation being required, a new solution was required. This is driven by the changing research goals. Andrew explained: "Our research is into wheat nutrition, particularly nitrogen use efficiency. We have recently expanded the field trials work to around 7,000 plots/year generating around 14,000 plant samples (grain + straw) which require nitrogen analysis. With so many samples, we were looking for a cheaper and quicker method of analysis."
"We chose the AgriSpec for a number of reasons. I like its robustness - much of our work is done in a lab. It is not a typical lab. We have thousands of relatively large samples, with associated dust and other contaminants. The range of attachments for the AgriSpec is good. By using the sample turntable, we can easily and rapidly estimate grain nitrogen content without having to mill the samples saving a lot of time."

New Standards set in Body Composition Monitoring
Monitoring the effectiveness of a weight loss or physical activity programme has never been easier or more accurate, with the MC780MA Multi Frequency Segmental Body Composition Analyser from Tanita.
The MC780MA uses the very latest multi-frequency technology to record a comprehensive range of measurements in just 20 seconds, from segmental fat and muscle mass to basal metabolic rate, visceral fat levels and total body water from your core abdominal area, each arm and leg.
A full body composition analysis will give you and your clients a base to start from and each subsequent reading can be used for long term assessments and progress reports. This will give you the chance to assess how effective the weight loss or physical activity programme is for each and every client, set progressive targets and modify the program according to their results.
This detailed information enables clients to see even the smallest changes happening to their body, motivating them to continue with their programme and work towards their end goal. It also allows you to educate clients on the importance of looking beyond BMI or weight only that cannot show changes in body composition as muscle increases and fat decreases.
The MC780MA is accredited with NAWI Class III and MDD IIa, has a weighing capacity of up to 270kg and auto calibrates before each and every analysis, ensuring optimum reproducibility of measurements. Numerous published clinical studies have proven Tanita BIA technology to be highly accurate and repeatable in a wide selection of cohorts including adults and children.
All results are shown on an easy-to-read, extra large LCD display console that can be reversed for confidential readings, or when very obese clients are using the scale.
The in-built SD card facility can store over 10,000 readings on a 2GB SD card, and allows data to be automatically collected and downloaded at your convenience. You can also wirelessly transfer data to a PC or Windows tablet. A consultation sheet can be printed automatically for further discussion.
The Client Identify feature allows for client body composition progress to be effortlessly recorded and analysed. LAB PRODUCTS MORE INFO. 525
