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...

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...
Raman vs SERS… What’s the Difference?
If you’ve ever had a conversation with a Raman spectroscopist about the feasibility of a low-concentration sensing application, chances are you’ve heard them say “well, Raman may not be sensitive enough…but maybe SERS will work!” But what’s the actual difference...
Fast determination of acid and base number by thermometric titration
Acid number (AN) and base number (BN) are critical parameters in the quality control of petroleum products as they are often stipulated by product specifications. Traditionally both parameters can be determined by potentiometric or photometric titration according to...
