Question 1

It measures particles which are too large for spectro

a. turbidimetry
b,. nephelometry
c. electrophoresis
d. chromatography

Answer 1

nephelometry

• light scattered
• It measures particles which are too large for spectro such as antibody-antigen complexes formed in EIA

Question 2

involved measurement of CURRECT/ VOLTAGE by the activity of specific ions

a. electrophoresis
b. electrochemistry
c. chromatography
d. mass spectrometry

Answer 2

electroCHEMISTRY
- current / voltage

include potentiometry, amperometry, coulometry, voltametry

Question 3

measurement of potential (voltage) between two electrodes in a solution to measure analyte concentration

a. potentiometry
b. amperometry
c. couolometry
d. voltametry

Answer 3

potentiometry

- potential (volatage) between two electrodes

Question 4

measurement of the current flow produced by an oxidation - reduction reaction

a. potentiometry
b. amperometry
c. couolometry
d. voltametry

Answer 4

amperometry

- current flow produced by an oxidation reduction reaction

Question 5

separation of charged compounds based in their electrical charge

a. electrophoresis
b. electrochemistry
c. chromatography
d. mass spectrometr

Answer 5

electrophoresis
- electrical charge

electrochemistry
- current / volatage

Question 6

uses pressure for faster separations

a. tlc
b. hplc
c. GC

Answer 6

chromatographic procedures

1. Thin layer chromatography
   
   • semiqualitative drug screening test
2. high performance liquid chromatogrpahy
   - for faster separations
3. Gas chromatography
   - volatile or can be made volatile
