RESPONSIBILITY
Doing : Technical Assistant
Checking : Executive /Manager
ACCOUNTABILITY
Head of the Department
PROCEDURE
- Check the performance of the instrument in terms of
- Linearity of spotting (Annexure-I)
- Reproducibility of spotting (Annexure-II)
- Prepare the mobile phase as per the method given in Annexure-I.
- Prepare the solution as mentioned in Annexure-I
- Use 10 X 10 cm HPTLC plate (Kieselgel 60F254 or Identical)

- Apply 2 μl, 4μl, 6μl, 8μl and 10 μl of solution on HPTLC plate with spotter.
- Allow the plate to run in mobile phase.
- Dry the plate with drier.
- Scan the plate with scanner.
- Check the linearity and corelation coefficient.
- Fill in the Data as mentioned in Annexure-I
Reproducibility of Spotting
- Apply 10μl solution on HPTLC plate for five times in sequence
- Allow the plate to run in mobile phase.
- Dry the plate with drier.
- Scan the plate with scanner.
- Calculate the RSD for five track ( RSD Limit : N.M.T 3.0%)
- Fill in the data mentioned in Annexure-II
