The KBr “eye” technique how to analyse by IR one microgram of sample in a KBr pellet pressed in an ordinary 13 mm dieA procedure is described for the trained analyst to obtain good IR-spectra with one microgram of solid compounds fit for KBr-analysis. The technique has been used ...
When smoothing data, it’s likely there’s no ground truth you’re aiming towards; just some noise in your measurements that hamper attempts to analyse it. Using the Whittaker smoother, we can vary λ to alter the level of noise removed from our data. Figure 1)Optical output of a galaxy...
Referendums allow people to participate in political decision-making. However, they also come with the challenge of presenting complex issues to the electorate in a concise and comprehensible way. In order to simplify the decision-making process, referendum questions are often tailored toyes/norespons...
analytical methods. Optical microscopy and electron microscopy provide the main contribution to identifying most of the processing practices on the clay, whereas bulk methods provide indirect evidence that may alone be insufficient to prove the occurrence of a specific transformation, as well as to dete...
Focused on uncoated ceramics, this tutorial paper is divided into two main sections. The first section deals with the operational phases required prior to

For spectra presenting multiple adducts, we summed the area of all adducts to obtain the total intensity corresponding to one compound. Analytical blanks confirmed that no memory effects or sample contamination skewed results. The concentration of the metabolites was assessed using a calibration with ...
