Frequently 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 amount of titrant included is chemically equivalent to the quantity of analyte in the sample. The endpoint is the physical point where a change is really observed (such as a color modification or a voltage spike). Professional titration services utilize automated sensors to ensure the endpoint is as near to the equivalence point as possible.
2. Why is Karl Fischer titration so typical?
Karl Fischer titration is unique since it is extremely specific to water. Unlike other techniques that might measure all unstable substances, Karl Fischer only responds with water, making it the industry standard for moisture analysis in a range of materials from liquids to solids.
3. For how long does a normal titration analysis take?
The period depends upon the sample complexity. A standard automated titration may take just a few minutes, while complex samples needing specialized dissolution or preparation may take several hours. The majority of expert services offer turnaround times varying from 24 hours to one week.
4. Can titration be utilized for samples that are not liquids?
Yes. Strong samples can be evaluated by liquifying them in an ideal solvent. If the solid is insoluble, a "back titration" or an extraction approach (especially in Karl Fischer analysis) can be used to determine the concentration of the target substance.
5. What are the limitations of detection for titration?
Modern automated titration services can spot concentrations down to the parts-per-million (ppm) level. For wetness analysis using Coulometric Karl Fischer, detection can even reach the microgram level.
