Recognition of endpoints (EP)
Like many of you, I gained my first practical titration experience during my chemistry studies in school. At this time, I learned how to perform a manual visual endpoint titration – and I can still remember exactly how I felt about it. Using a manual buret filled with...
Easy moisture determination in fertilizers by near-infrared spectroscopy
Blooms or bombs? As the global population steadily increases, it is important that sufficient crops are produced each year to provide enough food, clothing, and other products. Crops such as corn, wheat, soy, and cotton receive nutrients from the soil they are grown...
Real World Raman: Simplifying Incoming Raw Material Inspection
Raw material identification and verification (RMID) is a complicated process for a very important reason: it confirms the quality of the raw materials used in the manufacture of products that you put on and in your body. The complexity of RMID spans the spectrum from...
Analysis of prebiotics with IC-PAD: Improving AOAC 2001.02
Our diet is critical for our health. In the past several years, interest has increased in food additives and dietary supplements such as prebiotics like β-galactooligosaccharides (GOSs). The determination of total GOS contents in food and supplements is essential to...
Multiparameter analysis in fertilizers by thermometric titration
Agriculture without fertilizers is no longer possible – without them, today’s estimated global population of 7.9 billion people could not be supported. Fertilizers provide plants with much needed nutrients for optimal growth. The ideal fertilizer depends not only on...
Unmatched flexibility in online ion analysis: The 2060 IC Process Analyzer
When discussing chemical analysis, the first thing that comes to mind is a chemist working in the laboratory analyzing a sample.However, in the industrial process world chemical analysis is a much more complicated affair. In the metalworking industry for example,...
Supercharge your battery research – Part 1
Replacing traditional fuel-powered vehicles with battery-powered options is essential to reduce carbon dioxide (CO2) emissions. This greenhouse gas results from the combustion of fossil fuels, therefore limiting its input into the atmosphere will also influence global...
Recipes with Raman
Many of us have spent more time in the kitchen in the past year than usual, (re)discovering our culinary skills with varying degrees of success. Our pantries have been kept full, and our stoves on for a year (and counting) since our normal, social ways of life have...
Chemistry of Chocolate
Swiss… Belgian… Pure… Milk… Here we are in mid-February again, bombarded by chocolate from all sides in preparation for Valentine’s Day on the 14th. Whether in a solid bar, as a chewy truffle, or as a luxurious drink, chocolate has completely infiltrated our lives....
ASTM D6304: Easier determination of moisture in petroleum products
Water in petroleum products, such as lubricating oils, jet fuel, or other similar products can have deleterious effects. Moisture is often associated with corrosion and engine wear. Knowing the water content of petroleum products can prevent damage to costly...
