Analytical Chem. -measurement. in science

1. Quantitative Analysis identification

2. Qualitative- Numerical info.

Izaak Maurits kolthoff- (1894-1993)Father of Modern Analytical Chen.

Role of tra. Chem.

Research Areas

Intedisciplinary nature

Analytical Method - techniques used to identify -used in forensic , bio, cand envisci.

Classical Method - "wet chem" used a simple kab oglassware (Gravimetric Instrumental saentific intom instrument (spectroscopic Methods) Kralysis)

electromag radiation (spectroscopy)

epeetrical proper (electrochem. analysis)

Four general areas

1. Gravimetric methods determene mass of analyte

2. Volumetric- use volume of a solution

3. Electroanalytical measure ketrical properties

4. Spectroscopic based on interaction of electromagnetic rad.

Chemical Analysis- seasurement element

Feedback system- continous pleasurement and control

Feedback Loop- cycle of measurement, comparison and Control
