Answers to Endangered Animals Lies in their Scat

15 Nov 2013

By Pui Sai Lau, Web Writer.

Pui Sai Lau is a guest web writer for Analytical Methods. She is currently a PhD student at McMaster University, Hamilton, ON, Canada.

LC-MS for Animal Identification

Studying rare or endangered species of wild animals is no easy task. Analysis of animal tracks and fecal matter left behind can provide some clues for species identification, as well as insight into animal behavior and habitation. However, these identification signs are elusive, and often confounded by variations in environmental conditions, as well as animal health and diet. While methods of molecular analysis such as DNA sequence analysis of animal scat samples can provide more informative answers, DNA contamination from other mammals can make accurate identification difficult. To circumvent some of these limitations, Udaya Nasini, Ali Shaikh and colleagues from the University of Arkansas in Little Rock, USA, have demonstrated the use of liquid chromatography-mass spectrometry (LC-MS) to determine the composition of bile acids in scat samples. Analysis using LC-MS provides a metabolic pattern that is characteristic of a distinct species, and in turn enables effective identification.

Detecting iron the smart way

12 Nov 2013

By Katherine Dunn, Publishing Assistant.

Spanish scientists have developed a way to quantitatively measure the amount of iron in a solution using a colour changing material and photos taken on a smartphone.

Iron is present in almost every aspect of our lives but an excess, known as iron overload, can cause significant long term effects ranging from liver damage to arthritis as a result of iron deposition in organs or joints. As such, the amount of iron in a variety of environments needs to be carefully monitored.

Unlike traditional quantitative techniques, which require removing samples to the lab for assessment by trained specialists, the new approach devised by José Miguel García and colleagues at the University of Burgos can return a result within 15 minutes. Central to the technique is 8-hydroxyquinoline, a particularly stable iron chelator, which is immobilised on a polymer disk and will change colour depending on the amount of iron chelated to it.

Learning How to Use PARAFAC for Fluorescence Spectroscopy

18 Oct 2013

By Pui Sai Lau, Web Writer.

PARAllel FACtor analysis (PARAFAC) has been a tremendously instrumental tool for interpreting a wide-range of information including spectral, NMR, GS-MS, (HP)LC-DAD, EEG, geospatial, radar, sensory, metabolomic and image data. In effect, application of PARAFAC has resulted in advancements for diverse research areas including medical, pharmaceutical, food, environmental, social and information science. Notably, PARAFAC applications pertaining to analysis of fluorescence excitation emission matrices have been particularly popular. However, users are often confronted with many practical and analytical challenges when using PARAFAC for real-life applications.

To help simplify this procedure, Kathleen R. Murphy from Australia, along with Colin A. Stedmon and other colleagues from Denmark, provide an informative tutorial of the practical application of PARAFAC for fluorescence data analysis. This review provides deeper insight into preparing, modelling and interpreting fluorescence datasets particularly for environmental samples, and demonstrates a new software tool to facilitate PARAFAC analysis.

From Database to Data Interpretation Using PARAFAC
