Gradient elution parameters in capillary liquid chromatography for high-speed...Diane Infante
This study compared linear and non-linear models for predicting peptide and protein retention behavior under varying mobile phase compositions in capillary liquid chromatography. The linear model accurately predicted retention times under initial test conditions but the non-linear Neue–Kuss model was found to allow for high-speed separation predictions with errors less than 2%. While the linear model suggested peak broadening at high speeds, the non-linear model revealed peak sharpening effects, particularly for steep gradients. This model was determined to be more accurate for optimizing high-speed separations.

In this document , a brief outline of osteoporosis is given , including the risk factors of osteoporosis fractures , the indications for testing bone mineral density and the management of osteoporosis
9. Why? Six Reasons
1. Potency assays are key in making medicines
2. Bioassays are very variable
3. Statistics will help you understand your data
4. Understanding your data will reveal if control
exists
5. Your level of control allows you to judge RISK
6. Regulators globally require it 9
10. The Regulator & Assay Control
Regulators have been asking for this for years! QbD
1. Pharmaceutical cGMPs for the 21st
Century
2. PAT
3. ICH Q2: Validation of Analytical
Procedures
4. ICH Q8: Pharmaceutical Development
5. ICH Q9: Quality Risk Management
6. ICH Q10: Quality Pharmaceutical
Systems
10
15. Bioassays will always be variable
You can improve it
- by understanding it
- Focusing effort in right places
- This brings control
- You can manage expectations
- This is understood by regulators
15
16. Why assay variation matters?
product variation +
A few unsatisfactory
assay variation + batches may even
inaccuracy pass specification
due to a combination
of assay method and
process variability
Many satisfactory OOS batches likely to fail (potentially costing £Ms)
because of combination of assay method & process inaccuracy & variation

17. Our Control Strategy
What does the scientist need to achieve?

24. What’s Appropriate Knowledge?
• Learning takes time
• Will you use it often enough?
• It’s not an academic pursuit
• Activities must add value
do what’s necessary

Visual simulation of expected performance relative to specification
37
39. Validate & Verify
The evaluation of robustness should be considered
during the development phase and should show the
reliability of an analysis with respect to deliberate
variations in method parameters ICH Q2B, 1994
Method stretch…what if?

41. Working within the control
boundaries will keep the
assay under control
Even if you go outside
the control boundaries,
the assay will have
enough flexibility to
deal with it without an
OOS

44. Precision
It may be considered at three levels:
1. Repeatability
2. Intermediate precision
3. Reproducibility
ICH Q2A, 1994
45. Repeatability
1 analyst in 1 laboratory on 1 day injecting 6 times
Summary Statistics
Number of Standard Coefficient Lower 95% CI Upper 95%
Values Mean Deviation of Variation for Mean CI for Mean
t30 PS 6 223.27 6.43 2.88% 216.52 230.02
45
46. Intermediate Precision
• 1 analyst in 1 laboratory on
• 1 day
• injecting 6 samples
• each tested 6 times
As well as sample variation, this study still provides
information on repeatability
46
47. Intermediate Precision
So we compare the mean values for each sample
(over replicate results per sample)
Variance Components

48. and the others…..?
Precision within a laboratory but with
different analysts, on different days, with
different equipment…reflects the real
conditions within one laboratory
ICH Q2A 1995

49. Intermediate Precision
Data collect using several analysts using several instruments
over several days:

51. Intermediate Precision
better examined looking at multiple
sources of variation within an assay
want to understand
major sources of
variation such as
sample, prep,
analyst etc.
51
53. Intermediate Precision
Can also perform Unbalanced designs
One operator performs multiple injections on single
preparation;
Two operators perform single injections on multiple
preparations
53
54. Reproducibility
multiple laboratories; typically run as an inter-
laboratory cross-over study, with each participating
lab sending samples to every other lab and
analysing all samples (including own)
…. sent to and analysed by other lab
A B C
Samples from A
laboratory:
B
C
54
55. Reproducibility
Can use analysis of variance (ANOVA) to look for
differences or biases between labs
Alternatively look for “analytical equivalence”
56. Risk Management
The level of effort, formality and documentation..
..should be commensurate with the level of risk
ICH Q9
Evaluation of the risk to quality should be based on
scientific knowledge & ultimately link to the
protection of the patient
Is the bioassay fit for purpose and under control?

62. Summary
1.Build a good basic understanding of
stats but don’t need to become guru
2.Involve a statistician, at least at the
beginning
3.Build understanding of your bioassay
(QbD) – it’s a must
4.Get to grips with Bioassay Variability
