Often Asked Questions (FAQ)
1. What is the difference in between an endpoint and an equivalence point?
The equivalence point is the theoretical point in a titration where the quantity of titrant included is chemically comparable to the amount of analyte in the sample. The endpoint is the physical point where a modification is really observed (such as a color change or a voltage spike). Professional titration services utilize automated sensors to make sure the endpoint is as close to the equivalence point as possible.
2. Why is Karl Fischer titration so typical?
Karl Fischer titration is distinct because it is highly particular to water. Unlike other approaches that might determine all volatile substances, Karl Fischer only reacts with water, making it the market requirement for wetness analysis in a range of products from liquids to solids.
3. How long does a typical titration analysis take?
The period depends on the sample complexity. A standard automatic titration may take just a few minutes, while complex samples requiring specialized dissolution or preparation may take numerous hours. The majority of expert services use turnaround times ranging from 24 hours to one week.
4. Can titration be used for samples that are not liquids?
Yes. Solid samples can be analyzed by dissolving them in an ideal solvent. If the strong is insoluble, a "back titration" or an extraction technique (especially in Karl Fischer analysis) can be used to identify the concentration of the target substance.
5. What are the limits of detection for titration?
Modern automated titration services can detect concentrations down to the parts-per-million (ppm) level. For wetness analysis using Coulometric Karl Fischer, detection can even reach the microgram level.
