The Use of Statistical Process Control (SPC) Using Control Charts to Maintain Compliance in the Laboratory
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 things in the compliant laboratory. These generate a proactive system to assess problems early on and quickly to be handle by adjustments rather than the strict si..
Listening and Speaking Skills for the Laboratory
Most laboratory work does not rely on verbal communication skills, and so also this means few listening skills. Both are important when interacting with customers, when acting as a leader or supervisor, when trying to build and manage a project team, and in the day-to-day smooth operation of the laboratory.Listening skills, Understanding customers’ ways of thinking, recognizing differences in styles of thin..
BEST SELLER - 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 that is widely used to determine purity, the..
Issues in Calibrations and Accuracy in Method Validation
Accuracy, the ability for 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 ca..
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.Learning ObjectivesMany..
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 variables are common and can lead to different results. Making each operation..
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..
Implementing a Quality Management System
The Quality Management System (QMS) is a set of policies and protocols for the acceptable operation of an organization that contains laboratories that must comply with US FDA GLP. Examples of roles and responsibilities, useful metrics, and tools to monitor performance, and useful documentation will be given.Learning ObjectivesGLP RegulationsQuality Management System (QMS)DefinitionPrinciplesPurposeFunctionE..
