Spectroscopy

Is it time to drop your NIR instrument in the pool?

In this application note, one protein, interferon α-5, was conjugated with two different PEG molecules in different reactions.  The protein and PEG molecules were characterized individually using multi-detector SEC, followed by the PEGylated conjugates.  Their composition, molecular weights and intrinsic viscosities were measured. This work was performed by Celares GMBH, Germany with samples provided by DIGNA BIOTECH, Spain

The M908 took the top spot in our 2013 Innovation Awards – “Revolutionary technology; will be an inspiration for new generations,” said the judges. Here, four co-founders of 908 Devices describe the perfect storm that led to the creation of the world’s first handheld mass spectrometer.

Accurate measurement drives progress in science in immeasurable ways. Here, we celebrate a year’s worth of advances in The Analytical Scientist Innovation Awards 2014. What impact will these 15 TASIA winners have on your field?

I’ve been lucky enough to spend time in the grey area between analytical spectroscopy and atomic physics. It’s fascinating and enlightening – but is it chemistry?

Ever since the innovation injection that was the “Manhattan Project”, ion chromatography has defied probability by exhibiting almost continuous evolution

Spirit Sampling for counterfeit detection and brand authentication

Frequently asked questions related to the application of DLS to the characterization of protein therapeutic formulations

GPC/SEC can be used to characterize commodity or bulk manufactured polymers. Here we describe how the use of formic acid instead of hexafluoroisopropanol (HFIP) as the dissolution solvent and/or mobile phase can lead to improvements in both cost per analysis and health and safety.
