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 they deal with problems and the laboratory. Inter-personal skills in speaking, listening, negotiating, and other areas are needs that fall outside of the skill set of the l..
This course provides guidance on how to perform QC analytical test method validations and transfers. One of the most critical factors in developing and marketing pharmaceutical drug substances and drug products is ensuring that the analytical methods used for analysis can generate valid data upon which business and regulatory decisions can be made. FDA, ICH, and USP have each recognized the importance of th..
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 handled by adjustments rather than the strict s..
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..
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..
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..
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..
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 is common and can lead to different results. Making each operation ..
