5.1: Analytical Standards - Chemistry LibreTexts

A primary standard is a reagent for which we can dispense an accurately known amount of analyte. For example, a 0.1250-g sample of K 2 Cr 2 O 7 contains 4.249 × 10 –4 moles of K 2 Cr 2 O 7. If we place this sample in a 250-mL volumetric flask and dilute to volume, the concentration of the resulting solution is 1.700 × 10 –3 M.

Data standards: What are they and why do they matter? The

What Is A Data Standard?from Modelling to Representation and InteroperabilityHere Are A Few Examples of The Same Content Represented in Some Popular formats.What Aspect Do We Analyse?Think of a Master’s thesis that you have to write at the university. It consists of a title, abstract, the thesis itself and a bibliography. Oh, and it’s written as part of your curriculum and verified by other people. So you should specify the university, the faculty, the supervisor and the reviewer. As well as some audit logs: date of creation, last modification date, date of acceptance by reviewer (and his/her opinion), date of acceptance by supervisor. Probably also a bit of translation for the global community: a title and an abstract in English if the thesis is in some other language. Now let’s say that you want to create a tool to browse theses on any given subject. You need to gather a substantial number of theses and feed them into a computer. For that to happen you need to transform each thesis into a single data record. Planning how this data record will look like is called modelling. We model real life examples into data records. Modelling can drop some unimportant (arbi...
