The Transfer Of Validated Methods
This webinar will discuss the best practices of the transfer of validated methods including statistics of analytical methods, how to define universal methods, how to make the method operation uniform, training issues, and the use of transferring methods. Even... -
Statistical Process Control (SPC) and Control Charts for Laboratory Compliance
Compliance under GLP can be difficult. The setting up of a system to monitor the performance of methods and instruments can lessen this. Statistical Process Control (SPC) uses control charts and statistical guidelines to monitor a wide variety of... -
Instrumental Issues in GC and GC-MS for On-Going Validation
Instrumental gas chromatography as an analysis is widely used to determine purity, the impurities, and the degradation products of pharmaceuticals. The focus of most validation work is on the methodology, the standard operating procedure (SOP). But validation of the... -
Do’s and Don’ts in Effectively Dealing with Difficult Customers
Difficult customers can be much more than just an occasional irritation. They can damage the reputation of a laboratory, take up a lot more time than the average customer, and can disrupt operations. Difficult customers are varied in how... -
Statistical Process Control through the use of control charts and Nelson’s Rules
Statistics can be used to monitor critical variable in the running of a procedure and in the performance of the instrumentation that performs it. By applying Nelson’s rules this data can be evaluated as performing as expected or performing... -
Effective Handling of Issues in Calibrations and Accuracy under GLP
Accuracy, the ability of a methodology to give results within acceptable limits when compared to known values, is a fundamental and key requirement. Calibration is the most common approach to obtain accuracy. Accuracy requires a comparison to a validated... -
Key Elements of HPLC and UPLC Method Validation to Ensure Compliance with FDA and ISO Requirements
Instrumental liquid chromatography, either as HPLC or UPLC, are common techniques in laboratories that are widely used to determine purity, the impurities, and the degradation products of pharmaceuticals. The focus of most validation work is on the methodology, the... -
Analytical Method Validation under Good Laboratory Practices (GLPs)
Good Laboratory Practices training (GLP) is essential to any laboratory that supports products for sale or use in the United States. GLP much like GMP ensures a comprehensive system that guarantees validity of results and overall quality. Pharmaceuticals, chemicals,...
