Colorimetry
Lab technique used to measure concentration of a solution by the intensity of it's color
-
Beer's Law
The concentration of a solution is directly proportional to the amount of light absorbed by that solution and is inversly proportional to the amount of light transmitted thru the solution
-
4 different cuvettes needed for the spectrophotometer
- 1. Blank
- 2. Standard
- 3. Control
- 4. Patient
-
Blank cuvette
Contains reagent only. Used to Calibrate the machine to 100% transmitence.
-
Standard Cuvette
Standard solution only that has known concentration
-
Control Cuvette
Reagent + control solution, has an acceptable range of values
-
Patient Cuvette
Reagent + Serum
