Glycerin and glycerin (S)
Procedure for glycerin
1. Prepare the test according to the process specification.
2. Select STORED PROGRAMS > SELECT BY NUMBER.
3. Enter the number 2212 for the program "Glycerin". Confirm with
OK.
Enter the number 2213 for the program "Glycerin (S)" with creep
monitoring. Confirm with OK.
4. Press START to start the program.
5. Set the blank value cuvette to carousel position 1.
6. Set the sample cuvettes to carousel positions 2-7.
7. Press READ CAROUSEL.
The 7:00 timer starts. When the time elapses, two short acoustic
signals are sounded.
Extinction 1 is measured in all cuvettes. R1 is shown on the display.
8. Pipette the reagent into the blank value and sample cuvettes
according to the process specification.
9. Press READ CAROUSEL.
The 10:00 timer starts. When the time elapses, two short acoustic
signals are sounded.
Extinction 2 is measured in all cuvettes.
Note: In the case of program 2213 glycerin (S) with creep
monitoring, extinction 2 is measured six times in order to verify the
stability of the value and to preclude a subsequent creep reaction.
The result is indicated in g/L glycerin and g/100 g glycerin on the
display.
