Determining a Rational HPLC/UHPLC Selectivity Starting Point

Selectivity in a liquid chromatography (LC) separation is the ability to separate a molecule from other similarly structured compounds, such as conformational, positional, and optical isomers. Columns do this in a variety of ways that depend on the structural differences between the key target molecules. This is most commonly done by tailoring the column’s stationary phase so that the different target molec..

Method Validation of HPLC/ UPLC Methods

Instrumental liquid chromatography, either as HPLC or UPLC, are common techniques in laboratories that do regulatory-compliance work. For Good Laboratory Practice (GLP) or for ISO 17025 compliance, such methods must meet certain requirements. This presentation will cover the key elements to have a compliant method.Instrumental liquid chromatography is an analysis is widely used to determine purity, the impu..

Quality by Design (QbD) for Analytical Methods

This 60-minute presentation will highlight the use of statistical tools to monitor operations for a proactive operation.There are always certain steps in a method where control is critical either because this step contributes a lot to the overall uncertainty or its uncertainty is more likely to change from common causes. These critical points can be assessed and a monitoring program instituted. This data is..

Issues In Calibrations And Accuracy In Method Validation

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 material. The level of confidence depends on traceability, a chain connecting the samples of interest all the way to the specific metric standards. This can..

Monitoring a Quality Laboratory to Prevent Non-Compliance

Everyone in a laboratory under compliance knows about 3-sigma out-of-control issues. Can the operation be monitored to avoid these? How? This webinar will cover the basic statistics of compliance and non-compliance and how to use a statistical approach to monitor the operation to ensure that it is under control and to see when a problem is arising, but before it is outside of 3-sigma.Data quality and compli..

The Transfer Of Validated Methods

Even a detailed and well-written standard operating procedure for a method cannot ensure that 2 laboratories running on aliquots of the same will get statistically equivalent results. Using different instrumentation, standards, reagents, solvents, and other chemicals, data systems, sample storage, and handling procedures, and other variable are common and can lead to different results. Making each operation..
