Seminar Tanja and Lauterbach lecturs Flashcards
Defination of QC
it is system of maintaining standards in manufactured products by testing a sample of the output against the specification
What is analystical Quality Control
we have the QC in life science and instrumental analysis
QC in life science is for
Screening for impurities, determining API concentration
checking of compliance against standards
instrumental analysis
Chromatography
Spectroscopy
Crystallography
on what is AAS based on?
it is based on the fact that atoms in the ground state can sbsorbt certain wavelengths of the elctromagentic spectrum between 190 and 850 nm
What is observed in AAS and why
in AAS lower atomization temperatures are applied in comparison to AES
Most of the atoms are in the ground state and only transitions that emanate from the ground state , so-called resonance transition are observed
Areas of application in AAS
enviromental monitoring, food ontrol, material sciences, clinical chemistry, QC
What is validation?
provides a high degree of assurance that a specific process/method will consistently produce a product metting its predtermined specifications and quality attributes
Types of Validation
Process, cleaning,computerized system validation
Process Validation
is a data collection and assessment from production through to commerical manufacturing
Cleaning validation
methods must verift that coontamination and cross contamination from previous productions would be prevented
Computerized system validation
evaluation regarding their application, production and QC
what’s the purpose of Computerized system validation
it is to verify that the computerized system specification are appropriate for the user’s needs and intended use.
Method Validation
process of demonstrating that an analytical procedure is suitable for its intended purpose
three key words in process validation
documented evidence of the process, perform effectively reproducibly and so meeting the predtermined specifications
What is the importance of analytical procedure?
it is test a defined characteristic of the drug substance or DP against established acceptance criteria for that characteristic
what are validation characteristics
accuracy precision linerity specifity range robustness LOD LOQ
accuracy defination
closeness of agreement between the value which is accepted (concentration true value or accepted reference) and the value found
Precision defination
closeness of agreement between a series of measurements obtained from multiple sampling of the same homogeneous sample
repeatabilty
same operating conditions
reproducibility
between laboratories
Guidelines for Qualifications
EudraleX Volume 4, Annex 15, ICH, FDA, Active agent manufacturing regulation
Purpose of Q and V
Q: documented evidents that equipment is delivering expected results
V: documented evidence that the methods or processes deliver expected results by using defined equipment and parameters
Intended use of Q and V
Q: Facility, equipment, system
V: processes, method
Responsibility for Q and V
Q: Head or production and head of QC
V: Head of QC (theoretical), futher department (practical)
What is necessary before qualificationa and validation?
assessed for its risk by means of risk analysis tools, FMEA
what is verification
Verification is when a pH.Eur. method is used
(compendium method), the applicants have to show that the method used is verify
What does a qulification of an impurities mean?
You have to garantee that your impuries don’t excess the threshold
what’s the goal of validation
Is not to showed that your method, rather it must work inroutine practise, change of person, sites and parameter. it is un-going process, work under route and not ideal conditions
when sould methods be validated
Established methods, Revision of established methdos, method changes, comparison of methods, new method development
new reulatory guidelines
ICH guidlines for validation means one has fulfilled everything
it is not a checklist, deviation from the guidline is allowed but has to be justified
What is a Re-validation?
Applicant ahs to make sure that the actuality producer is working
Who us responsible for the kind of the validation procedure used?
the responsibility is of the applicant
Types of analytcial procedures to be validated
identfication of your product
qauntitative test
quantitative tests for impurities
what kind of test for impurities is possible?
Either a quantifiction or a limit test
