ANALYTICAL CHEMISTRY (CM 2134)
SUMMARY LECTURE NOTES 1-2 FOR
ANALYTICAL CHEMISTRY CONCEPTS
NATIONAL (2025-2026) GUIDE UNIVERSITY
FOE SINGAPORE
, Lecture1,2 summary -intro to analytical chem
So analytical chem involves qualitative and quantitative analysis
- Qualitative to determine the chemical identity of species in a sample
- Quantitative to determine the relative amounts of these species (called analytes)
- An analyte is the chemical species to be identified/quantified
- The matrix is the remainder of the sample
- A sample is the substance of interest,
representative of the remaining sample that isn’t
collected (at least we assume tis representative)
A possible experimental method is titration, which is
pretty useful. But it isn’t useful for all things sadly.
Like solids like manganese, tis hard because we need
to get it in the correct form for titration first
The point of step 3 is just to make sure that the
manufacturer made the instrument properly lmao
There’s other stuff to consider
- Economic cost
- Amount of sample viable for analysis (if too
little then RIP)
- How complex is sample
- Required accuracy, precision, sensitivity, detection
level for the results etc.
The thing below is a flowchart for gravimetric analysis.
I’m lazy to type it out so here’s the picture
